KEY POINTS

  • Physicists achieve a noise level 10 times lower than the previous record
  • Demonstration proves to take a major step closer to a full-scale silicon quantum processor 
  • Next step could be a 10-qubit prototype quantum integrated processor by 2023

The lowest noise level on record for a semiconductor quantum bit has been demonstrated by a team of quantum physicists, bringing the development of a commercially available silicon quantum computer one step forward to possibility. 

In a study published in Advanced Materials, the physicists said they were able to achieve a noise level 10 times lower than previously recorded for any semiconductor qubit. Specifically, they demonstrated a low-level charge noise of  S0 = 0.0088 ± 0.0004 μeV2 Hz−1. 

As a next step, the team is now looking forward to demonstrating the capability required to produce a reliable 10-qubit prototype quantum integrated processor by 2023. 

“Our team is now working towards
