Description of the Research Areas in Quantum Information and Communication
Quantum information and communication is a field that combines quantum physics with information science to process, transmit, and store information using quantum systems. Unlike classical bits, which can be either 0 or 1, the basic unit of quantum information—the qubit—can exist in a superposition of both states simultaneously. A key resource in this field is entanglement, a non-classical correlation between qubits that enables tasks impossible with classical resources.These properties enable revolutionary applications such as quantum key distribution, quantum teleportation, quantum network, quantum internet, to name a few.
At our centre, we undertake research on various aspects of quantum information and communication, and related topics —
- Bell non-locality and its applications in quantum information processing tasks
- Quantum information with continuous-variable systems
- Entanglement and its characterisation in multipartite quantum states
- Quantum correlations and their applications in quantum information processing
- Quantum information in optomechanical platforms
- Noise, decoherence and quantum error corrections
- Thermodynamics of quantum information
- Entanglement distribution and communication over a quantum network
- Secure communication and quantum cryptography
