Project: Applications of Quantum Information (Q-98)

Institute: S. N. Bose National Centre for Basic Sciences, Kolkata

Principal Investigator: Prof. Archan S. Majumdar

Co-Principal Investigator: Prof. Dipankar Home

Recently, several critical questions have surfaced in Quantum Information Science, such as:

  • The Nature of Quantum Correlations beyond Entanglement,
  • The Relationship of the Uncertainty Principle with Quantum Contextuality and Nonlocality, and
  • The Preservation of Entanglement through Weak Measurements.
And in addressing these questions, the crucial overlap between Quantum Foundations and Quantum Information is highlighted, underlining the persisting relevance of fundamental aspects of Quantum Physics even in technologically promising areas.


In this project we propose to perform concerted and focused investigations into the following well-defined though interconnected directions:

  1. Self-Testing in the One-Sided Device Independent Scenario,
  2. Preservation of Quantum Correlations in Noise Channels using Weak Measurements,
  3. Exploring Resources for Quantum Information Processing beyond Entanglement.


Some expected outcomes of this project are:

  1. Formulation of Self-Testing Bounds for Qubits and Self-Testing Quantifiers for Higher Dimensional Systems,
  2. Development of Resource Theories of Non-Markovian Noisy Channels and their Detection,
  3. Information Processing Protocols using Coherence, Superlocal Correlations, and Weak Measurements as Resource and Quantification of the advantage of using Simultaneous Quantum Correlations in Complementary Basis.
