Detection of quantum information stored in nuclear quantum bits using light

A way to use electron and light for communicating with a large number of quantum bits and to understand its behavior thereby detecting a quantum bit from many has been discovered. Thanks to the researchers at the University of Cambridge for the discovery.

To a haystack of a large number of nuclei highly quantum information was injected with the help of a needle. With the help of the lasers, they controlled the electron. With this electron then the haystack behavior was controlled and thereby finding the needle more easily. Researchers detected the needle with better precision, thus detecting the quantum bit from many.

Light channels transmitting quantum information are going to be the right candidates for a quantum internet. Today, other than the semiconductor quantum dot there is no quantum light source. The one challenge faced by both quantum internet and quantum dot is that storing quantum information is not possible.

Professor Mete Atatüre from Cambridge's Cavendish Laboratory said that " a fine solution to this problem is storing the quantum information in 1,00000 nuclei present in each quantum dot. But when communication is done they show a tendency of flipping, thereby creating a noisy system"

Future plans

  • Store and retrieve the quantum bit from the nuclear register.

Advantages

  • Useful for quantum Internet.
  • Useful for solid state-based quantum computing.
  • Send information to the quantum bit and listen to the spins with less disturbance.
