    • Majorana zero modes, which are their own antiparticles, possess unique properties that could make quantum computers more robust and computationally superior.

    Majorana Fermions: A conceptual backgrounder

    • Fermions and Antiparticles: All subatomic particles that constitute matter are known as fermions, with each fermion having an associated antiparticle that annihilates upon interaction.
    • Majorana Fermions: In 1937, Italian physicist Ettore Majorana discovered that certain particles, known as Majorana fermions, can satisfy specific conditions and be their own antiparticles.
    • Neutrinos as Potential Majorana Fermions: Neutrinos are one type of subatomic particle that scientists speculate may exhibit Majorana fermion behavior, although experimental confirmation is still pending.

    Understanding Majorana Zero Modes

    • Quantum Numbers and Spin: All particles have four quantum numbers, with one called the quantum spin having half-integer values for fermions. This property allows any fermion, even a large entity like an atom, to be classified as a fermion.
    • Bound States and Fermions: Bound states composed of two particles can also be classified as fermions if their total quantum spin possesses a half-integer value.
    • Majorana Zero Modes: When these bound states are their own antiparticles and do not readily de-cohere, they are known as Majorana zero modes, which have been sought after by physicists for many years.

    Easy explained: Majorana Zero Modes

    In the world of physics, particles can have interesting properties and behave in strange ways. One type of particle that scientists have been studying is called a Majorana particle.

    Majorana particles have a special property called “non-Abelian statistics.” Without getting too technical, this property means that when two Majorana particles come close together, something interesting happens. Instead of behaving like normal particles, they can combine in a special way to form a new kind of particle called a Majorana zero mode.

    A Majorana zero mode is a very peculiar particle because it is its own antiparticle. Normally, particles have antiparticles with opposite properties, like an electron and a positron. But Majorana zero modes are special because they don’t have separate antiparticles. They are their own antiparticles!

    Potential Benefits for Computing

    • Enhanced Stability: Majorana zero modes offer increased stability for qubits, the fundamental units of information in quantum computing. Even if one entity within the bound state is disturbed, the qubit as a whole can remain protected and retain encoded information.
    • Topological Quantum Computing: Majorana zero modes can enable topological quantum computing, which takes advantage of non-Abelian statistics. These statistics introduce an additional degree of freedom, allowing algorithms to produce different outcomes based on the order in which steps are performed.

    Challenges and Future Prospects

    • Creating Majorana Zero Modes: Scientists have been exploring various setups, such as topological superconductors, to generate Majorana zero modes. However, confirming their existence remains a challenge, as their effects on surrounding materials must be inferred indirectly.
    • Recent Advances by Microsoft Researchers: Microsoft researchers recently engineered a topological superconductor using an aluminium superconductor and an indium arsenide semiconductor. Their device passed a stringent protocol, suggesting a high probability of hosting Majorana zero modes.

    Future prospects

    • While this achievement is significant, the existence of Majorana fermions and their potential for topological quantum computing still need independent confirmation.
    • Continued improvements in simulation, growth, fabrication, and measurement capabilities are necessary to achieve the desired topological gap for coherent operations.

    • Disease Understanding and Treatment: By collecting samples and health information from individuals with specific diseases or genetic conditions, biobanks facilitate research on disease etiology, progression, and treatment options.
    • Precision Medicine and Personalized Healthcare: By analyzing genetic and molecular data stored in biobanks, researchers can identify individual variations and develop tailored treatment approaches based on a person’s unique genetic makeup.
    • Public Health and Epidemiology: By analyzing large-scale data sets from biobanks, researchers can identify risk factors, understand disease prevalence, monitor disease trends, and develop strategies for disease prevention and public health interventions.
    • Drug Development and Clinical Trials: Biobanks play a crucial role in drug development and clinical trials. They provide researchers and pharmaceutical companies with access to well-characterized biological samples and associated health data, which are essential for evaluating drug efficacy, safety, and side effects.

    Inequitable Data Collection and Benefit Deployment

    • Global South Underrepresentation: The the majority of biobanks are housed in North America and Europe, covering about 95 percent of the biobanks globally. In contrast, the Global South, including India, only hosts approximately 5 percent of the world’s biobanks. This underrepresentation limits the Global South’s participation in health research and the deployment of health initiatives.
    • Research Bias: Due to the concentration of biobanks in the Global North, there is a bias in research and funding, focusing on genetic conditions and diseases that are prevalent in those regions. This bias hamper research on health challenges specific to the Global South, limiting the relevance and applicability of the findings to the populations in these regions.
    • Dissonance in Results: There is a dissonance in using samples from the Global South to cater to health requirements primarily in the Global North. This dissonance implies that research outcomes derived from data collected in the Global South may not adequately address the healthcare needs and challenges faced by the populations in that region.
    • Lack of Equitable Benefit Sharing: The lack of explicit return on results policies leads to inadequate sharing of benefits derived from the data collected in the Global South. The benefits and outcomes of research conducted using biobank data from the Global South are not shared equitably among the countries and populations from which the data originated.
    • Inequities During the Pandemic: The article cites an example of inequity during the COVID-19 pandemic, where the capacity of Afrigen, a biotech firm responsible for vaccine production in Cape Town, was limited due to the desire of private sector participants like Moderna and Pfizer to preserve their knowledge. This resulted in Africa’s reliance on global vaccine manufacturing, with only 1 percent of vaccines consumed on the continent being manufactured within Africa.

    India’s contributions and leadership in the bioeconomy

    • Healthcare and Vaccine Development: India has actively contributed to healthcare and vaccine development. The country has been involved in SARS-CoV-2 vaccine development, deployment, and diplomacy. Its expertise and participation have played a crucial role in addressing global health challenges.
    • Global South Representation: India’s involvement in advocating for global South representation in biobanking governance and global platforms demonstrates its commitment to addressing inequities. India’s leadership contributes to fostering collaboration, trust, and fair participation among countries in the Global South.
    • Multilateral Engagement: India’s association with the Quadrilateral Alliance and its G20 presidency provide platforms for global diplomacy and collaboration. These engagements enable India to advocate for global governance structures and mechanisms that promote equitable access, benefit sharing, and funding in the bioeconomy.
    • National Guidelines and Best Practices: India has established guidelines and best practices for biobanking, ethical data storage, sharing, and benefit distribution. The Department of Biotechnology and the Ministry of Science and Technology have played key roles in formulating these guidelines, ensuring responsible practices in the bioeconomy.
    • Exporting Health Information and Data: India has a history of exporting health information and data, which positions it as a contributor to global health initiatives. Leveraging its experience, India can emphasize the prioritization of diseases relevant to the Global South, prevent biopiracy, and establish rules for benefit sharing to benefit countries in these regions.
    • Global Diplomacy and Platforms: India’s involvement in global platforms, such as the G20 presidency, has enabled it to expand its national regulations and contribute to the establishment of a global governance structure for biobanking and data sharing. This allows India to advocate for relief from trust issues, mechanisms for benefit sharing, and incentives for funding in the Global South.

    Way forward: Addressing Inequities through Global Governance

    • Global South Representation: There is a need for greater representation of the Global South in global governance structures. This ensures that the specific requirements and perspectives of the Global South are considered in decision-making processes and policies.
    • Global Guidelines for Biobanking: There is need of the formulation of global guidelines for biobanking to establish standards and best practices. These guidelines would address ethical data collection, storage, sharing, and benefit distribution, taking into account the specific needs and concerns of the Global South.
    • Equitable Benefit Sharing: It is important to explicit return on results policies to ensure equitable benefit sharing. These policies would ensure that the benefits derived from data collected in the Global South are shared back with the countries and populations from which the data originated.
    • Collaboration and Knowledge Exchange: Global governance in the bioeconomy should foster collaboration, knowledge exchange, and technology transfer between countries and regions. This collaboration helps address disparities, build trust, and promote capacity-building efforts in the Global South.
    • Addressing Obstacles and Barriers: Global governance should address obstacles and barriers to data hosting, collection, and sharing in the Global South. This may include financial constraints, technological limitations, and infrastructure gaps that hinder effective participation and contribution.
    • Private Sector Engagement:  It is essential to define the role of the private sector in research and emergencies. Global governance should encourage responsible and ethical private sector engagement, fostering investment, innovation, and knowledge sharing in the Global South.

    Conclusion

    • The promotion of equitable governance in biobanking is crucial for advancing scientific research, ensuring equitable healthcare, and addressing the unique healthcare challenges faced by the global South. The time is ripe for India to champion this cause and drive transformative change in the field of biobanking on a global scale.
