Reading out the information from qubits without destroying them

Reading out the information from qubits without destroying them

A team of physicists at University of Colorado and NIST demonstrated that it could read out the signals from a type of qubit called a superconducting qubit using laser light, and without destroying the qubit at the same time.

The group’s results could be a major step toward building a Quantum Internet. Such a network would link up dozens or even hundreds of quantum chips, allowing engineers to solve problems that are beyond the reach of even the fastest supercomputers around today. They could also, theoretically, use a similar set of tools to send unbreakable codes over long distances.

The work has been published in the journal Nature.
