Quantum Communication & Cryptography

Quantum communication leverages the unique properties of quantum mechanics, such as superposition and entanglement, to enable fundamentally secure information transfer. Unlike classical communication, it offers provable security against eavesdropping, making it crucial for the future of global communication networks.

Research directions

1. Quantum key distribution

2. Quantum random number generators

3. Quantum repeaters and memories

4. Quantum networks

Future Directions and Potential Applications

Quantum communication holds immense potential for various applications:

  • Unconditionally secure communication: Protecting sensitive data for governments, financial institutions, and critical infrastructure against all forms of cyberattacks, including those from future quantum computers.

  • Distributed quantum computing: Connecting multiple quantum processors to create a more powerful distributed quantum computer, overcoming the limitations of single-site quantum machines.

  • Quantum internet: Enabling secure access to quantum computing resources over a quantum network, allowing users to perform quantum computations remotely without compromising data privacy.

  • Secure randomness generation: Generating unconditionallly secure random numbers between spatially separated parties.

CQST is at the forefront of these developments, contributing to both the theoretical understanding and experimental realization of next-generation quantum communication systems.
