Prelims level: Qubits, Quantum Mechanics etc.
Mains level: NA
In the news
Quantum computing holds immense potential, yet many systems operate only at extremely low temperatures, making them costly and commercially unfeasible.
Researchers are exploring alternative technologies to drive down costs and enhance the commercial viability of quantum computers.
Quantum Computing
Quantum computing is a paradigm of computation that utilizes principles from quantum mechanics to process information.
In quantum mechanics, particles exhibit wavelike properties, and their behavior is governed by the Schrodinger equation, which describes how these waves behave.
Key Concepts:
Wave-Particle Duality: Quantum objects, like electrons and photons, exhibit both particle-like and wave-like properties simultaneously, known as wave-particle duality.
Superposition: Objects in quantum science can exist in superposition states, where their quantum state is a combination of multiple states until measured. This concept allows qubits to represent multiple states simultaneously.
Quantum States and Qubits: Qubits are the fundamental units of quantum information, representing a two-state quantum system that can be in a superposition of 0 and 1 until measured.
Quantum Gates: Quantum computers use quantum gates to manipulate qubits through reversible unitary transformations, enabling complex computations based on algorithms.
Entanglement: Quantum entanglement is a unique property where multiple qubits can be correlated in such a way that the state of one qubit is dependent on the state of another, allowing for powerful computational capabilities.
Understanding Qubits and their Fragility
Classical vs. Quantum: Similar to classical computers, which rely on bits with two states (0 and 1), quantum computers operate using qubits—physical systems with two quantum states.
Unique Feature: Unlike classical bits, qubits can exist not only in one of the two states but also in a superposed state, where they simultaneously hold both states. However, this superposition is fragile and prone to disruption from external interactions.
Challenges in Qubit Implementation
Requirement for Identical Qubits: A collection of qubits is necessary for a quantum device, each needing to be identical—a challenge due to manufacturing imperfections.
Controllability and Robustness: Qubits must be controllable, allowing manipulation and interaction, while also being robust enough to maintain quantum features at room temperature over extended durations.
Exploring Qubit Systems
Diverse Options: Various physical systems serve as qubits, including superconducting junctions, trapped ions, and quantum dots. However, these systems typically require low temperatures or vacuum conditions for operation.
High Cost Barrier: The necessity for such conditions renders quantum computers based on these technologies expensive, prompting research into simpler, cost-effective alternatives.
Breakthrough in Room-Temperature Qubits
Metal-Organic Framework (MOF): In a recent collaborative study reported in Science Advances, researchers in Japan achieved qubits at room temperature within a metal-organic framework.
Composition: The MOF consists of repeated molecular arrangements, with zirconium as the metal component and an organic molecule containing the chromophore pentacene bridging the metal atoms.
Singlet Fission Mechanism: Singlet fission, facilitated by interaction between chromophores within the porous MOF networks, generates two triplet excited chromophores from a singlet excited state.
Enhanced Stability: The rotation of chromophores within the MOF networks modulates interactions, ensuring long-lived coherence of triplet states even at room temperature.
Just as the sporting world anticipates the Olympics every four years, the cryptocurrency community eagerly awaits its own quadrennial event: the Bitcoin halving.
Scheduled for April, this event marks a crucial milestone in the world of Bitcoin mining and trading.
Bitcoin
Bitcoin is a digital currency created in 2009 by an unknown person or group using the pseudonym Satoshi Nakamoto.
It operates on a decentralized distributed ledger called blockchain, which records all transactions.
The blockchain acts as a public ledger where each new set of verified transactions (a “block”) is added to the existing chain, creating an unalterable history of all Bitcoin transactions.
The process of verifying these blocks, referred to as mining, requires solving complex mathematical problems, which not only secures the network but also rewards miners with newly minted Bitcoins.
What is Bitcoin Halving?
Reward Reduction: Bitcoin halving entails a 50% reduction in the reward paid to Bitcoin miners for successfully processing cryptocurrency transactions. This reduction aims to maintain the scarcity of Bitcoin and regulate its supply.
Mining Process: Bitcoin miners utilize advanced computer equipment to solve complex mathematical puzzles through a process called ‘Proof of Work,’ crucial for expanding Bitcoin’s blockchain.
Blockchain Integrity: The halving mechanism ensures the integrity and security of the Bitcoin blockchain by adjusting the rate at which new coins are created, maintaining a controlled inflation rate.
Analogical Explanation
Grocery Store Contest: Analogous to a group of cashiers competing to tally up items in a grocery store, Bitcoin miners race to solve cryptographic puzzles to claim rewards.
Equipment Advantage: Cashiers with superior equipment have a higher chance of winning the contest, akin to Bitcoin miners with cutting-edge technology.
Economic Incentives: The analogy highlights the economic incentives driving both miners and cashiers to optimize their resources for maximum efficiency and profitability.
Implications for Crypto Investors
Scarcity and Value: Bitcoin halving reduces the rate at which new coins are released, enhancing Bitcoin’s scarcity and potentially driving up its value, similar to gold.
Historical Context: Bitcoin halving occurs approximately every four years, with past events influencing market dynamics and investor sentiment.
Market Speculation: Investors often speculate on the impact of halving events, with some anticipating price surges while others remain cautious due to the unpredictability of market reactions.
Impact on Mining and Market Dynamics
Corporate vs. Individual Miners: Corporate miners may prioritize maximizing rewards before the halving, while individual traders and investors may strategize based on market trends.
Geopolitical Factors: Shifts in mining operations across different countries, driven by factors like regulatory changes and electricity costs, influence Bitcoin’s ecosystem.
Technological Advancements: The evolution of mining hardware and techniques plays a significant role in determining mining efficiency and profitability, especially in the lead-up to halving events.

Scientific research in Indian universities is declining, because a career in science is not as attractive as business professions, engineering, or administration, and the universities are becoming consumer-oriented. Critically comment. (2014)
Why in the News?
The persistence of outdated frameworks in the conduct of scientific meetings in India is affecting its scientific practice.
Context:
There is a need to revamp the traditional mode of scientific conferences in India to align with contemporary values of egalitarianism, diversity, inclusivity, accessibility, and sustainability.
By modernizing these conferences, India can enhance its position in the global science and technology research ecosystem.
The article emphasizes ‘‘No Garland Neuroscience’ that science in India should reflect and promote these values in its practice and dissemination to support broader societal conversations.
How are the present scientific meetings held in India?
The Core groups of organizers are responsible for planning, inviting experts, disseminating info, and fundraising. It includes invited speakers and paid attendees sharing the latest research discoveries.
Scientific meetings, or conferences, are where researchers with similar or aligned areas of interest gather and serve as important avenues for the discussion and dissemination of science.
These meetings often include presentations or talks on contemporary research findings, along with expert interactions on topics of science and professional development.
Challenges associated with the Traditional ‘bouquet giving’ model:
Persistent outdated practices:
Persistent outdated practices perpetuate long-standing academic challenges and career-stage inequities.
For example, continued reliance on bureaucratic, hierarchical frameworks, prolonged opening speeches by science administrators, delayed commencement due to dignitary arrivals, and hierarchical seating arrangements.
Ignoring gender and diversity issues:
Inclusivity: Lack of gender and diversity awareness evidence lines up for the limited acknowledgment of wider diversity issues.
For example, all-male speakers or panelists and sessions such as ‘Women in Science’ completely fail to account for larger diversity issues in science, such as historically marginalized groups and LGBTQIA+ scientists.
Scientific ecosystem: In light of demands for secular scientific practice, gender, and social inclusivity, it is essential to reassess the practices like – religiously symbolic conference materials (like lamp lightening) or devotional songs during inaugurations, and gifting rituals in the Indian context.
What is the ‘No Garland Neuroscience’ (NGN) model?
The annual meeting series of NGN, uses a simple, sustainable, and low-in-cost approach, while keeping the focus on the scientific content and discussions.
Initiated in 2009, the Young Investigators’ Meeting (YIM) series from India Bioscience has focused on scientific networking and mentorship among life scientists in India.
They have continued with ‘no-garland’ features’, for example, speaker lists in alphabetical order, round table seating, equal gender representation, open interactions among scientists who are in every stage of their careers.
Hence there is absence of religious symbolism, formal inaugural ceremonies, and salutations for speakers, and souvenir and bouquet distributions.
How ‘No Garland Neuroscience’ (NGN) model can be significant for Indian scientists?
Can counter the Traditional Framework: The contemporary implementation of NGN can counterbalance the long-standing issue of outdated frameworks in the conduct of the majority of scientific meetings in India.
The conduct of scientific meetings can make planning and budgetary room for improved practices such as hybrid and multi-hub conference formats.
Can Revamp the Ecosystem: Outdated practices fuel inequities and overlook diversity challenges. Hybrid conference formats, code of ethics, diversity inclusion, care caregiver support can propose towards new scientific ecosystem in India.
To enhance India’s position in the global science ecosystem a more equitable and progressive scientific community can be built using the capability of NGN model.
Conclusion: Revamping scientific conferences in India to align with modern values of inclusivity, diversity, and sustainability is crucial for fostering a more equitable and progressive scientific community. Embracing these changes can not only address current challenges but also position India as a leading player in the international science and technology research landscape.

Military Confrontation: Rani Chennamma led the Kittur army in a fierce battle against the British forces, resulting in the death of British official John Thackery.
Doctrine of Lapse
Introduced by Lord Dalhousie in 1848, the Doctrine of Lapse aimed at expanding British territories in India.
The policy was based on the principle that a princely state without a suitable heir should become part of the British Empire.
Applied to princely states where the ruler died without a natural or legally adopted male heir, enabling the British to annex those states.
The policy was seen as illegitimate by many Indian rulers and played a role in the Indian Rebellion of 1857.
Several states annexed due to this Doctrine, include Satara (1848), Jaitpur (1849), Sambalpur (1849), Udaipur (1850), Jhansi (1853), and Nagpur (1854).
Prior to the Doctrine of Lapse, princely states had a traditional practice of selecting an heir from a group of candidates known as bhajans.
The policy was abandoned in 1859, two years after the end of the Company Rule in India.
Legacy of Rani Chennamma
Political Leadership: Rani Chennamma’s role as an astute administrator and seasoned stateswoman is highlighted in historical records.
Popular Perception: Despite her contributions, Rani Chennamma’s significance in national consciousness emerged later, as Karnataka became a state much later than other regions.
Historical Interpretation: Folklore and local traditions fondly remember Rani Chennamma’s bravery and resilience, portraying her as a protector and guardian in Kannada lavanis or folk songs.
Post-Rebellion Period
Imprisonment and Death: Following the British capture of Kittur Fort in 1824, Rani Chennamma and her family were imprisoned. She passed away in captivity in 1829.
Historical Records: Historians emphasize Rani Chennamma’s commitment to serving her people, even during her imprisonment, as evidenced by her efforts to support her family and people.

Prelims level: Singhbhum Craton, Archaen Eon
Mains level: NA
Why in the News?
Some recent study about the Singhbhum Craton in India, reveals that explosive volcanic eruptions were frequent around 3.5 billion years ago in regions that are also present in South Africa, and Australia.
What are Cratons?
Cratons are stable, ancient portions of the continental lithosphere, consisting of Earth’s two topmost layers—the crust and the uppermost mantle.
Cratons are typically found in the interiors of tectonic plates and are characterized by their ancient crystalline basement rock, often dating back to the Archean Eon.
Mantle plumeevents have played a significant role in the evolution of cratons.
About Singhbhum Craton:
The Singhbhum Craton is a geological region in India.
Location: It is located in eastern India, covering parts of the states of Jharkhand, Odisha, and West Bengal. The craton is separated from the Bastar Craton by the Mahanadi Graben and is in the vicinity of two Proterozoic mobile belts: the Satpura Mobile Belt and the Eastern GhatMobile Belt.
Geological features:
The rocks in the Singhbhum Craton are predominantly of Archean age, ranging from Paleoarchean to Paleoproterozoic.
It is a part of the larger Indian Shield, which is a stable continental crust that formed during the Archean Eon.
The Singhbhum Craton is known for its abundant occurrences of Banded Iron Formations (BIFs), which are closely associated with basic volcanic and ultrabasic intrusive. The craton is also known for its iron ore deposits, which are found in the Iron Ore Group (IOG) and are closely associated with lavas and tuffs.
The Singhbhum Craton has undergone regional metamorphism of the amphibolite facies and is believed to have evolved as a consequence of multiple phases of compressive deformation.
The craton is made up of multiple pulses of discrete mantle plume events, resulting in a complex geological history.
Archaean Eon
The Archaean Eon, one of the two formal divisions of Precambrian time, began about 4 billion years ago and extended to the start of the Proterozoic Eon.
During this period, life on Earth was limited to simple single-celled organisms lacking nuclei, known as Prokaryota.
The atmosphere lacked oxygen, and the Earth’s crust had cooled enough to allow the formation of continents.
Volcanic activity was considerably higher than today, with numerous lava eruptions.
The oldest rock formations exposed on Earth are from the Archaean Eon.
The Archaean rock system includes Archaean Gneisses and Schists, which are the oldest metamorphosed rocks found in abundance in regions like the Dharwardistrict of Karnataka.
What are the recent key findings?
Submarine Mafic Volcanism: The prevalence of submarine mafic volcanic eruptions between 3.5 and 3.3 billion years ago is documented, enriching our understanding of ancient volcanic and sedimentary processes.
Geodynamic Insights: Comparative analysis enhances our comprehension of early Earth tectonic activities and surface/atmospheric processes during the Archaean.
Research Methodology Used:
Field Studies and Radiometric Dating: Detailed field-based studies coupled with uranium-lead radiometric-age dating were employed to establish geological timelines and understand magma crystallization.
Comparative Analysis: The geological similarities between the Singhbhum Craton and counterparts in South Africa and Australia were studied, focusing on volcanic eruption patterns.
Implications and Significance of the study:
