Raman Research Institute

• Researchers from Raman Research Institute (RRI) have devised a new test for fairness of quantum coin or ‘qubit’ (the basic unit of information in a quantum computer) using entanglement theory.

About:

• Entanglement is a special type of correlation that exists in the quantum world with no classical counterpart. The researchers from RRI made use of this quantum resource to arrive at a test for fairness of a quantum coin (a qubit).
• This work is a significant contribution to the domain of quantum state discrimination, which is an essential aspect of quantum information science.
• It brings out the crucial role of entanglement in improving our ability to discriminate quantum states. Such advantage is valuable in quantum sensors.
