AFRL measures first superconducting quantum bits (qubit), first-ever demo for a DOD service lab

ROME, N.Y. – Researchers at the Air Force Research Laboratory Information Directorate here have measured the energy relaxation and coherence times of superconducting quantum bits (qubits), two important characteristics that determine how long qubits can retain quantum information.

This achievement is an important milestone toward AFRL’s objective of developing and adapting quantum technologies for quantum networking and quantum information processing.

Critically, researchers here observed the coherence times to be in excess of 0.2 milli-seconds, on par with state-of-the art superconducting quantum processors operating in industry and the academic community, and indicative of exquisite cryogenic microwave engineering capabilities at AFRL which will be applied to develop quantum-networking capabilities.
