- 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.
