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.
