10 May 2022 — Diraq, the spin off from SQC, has demonstrated universal gates for two qubits in a silicon double quantum dot and has a pathway to an ...
To answer our question Yep ,it was something I also said might be possible in normal silicon substrate using si28 also because of the reduced heat by a factor of 10.
'To overcome this problem, a qubit was created using an electron trapped by electrodes inside a thin film of purified silicon, comprising only the silicon-28 isotope. As this isotope is completely devoid of magnetism, it does not disturb the quantum bit, yet it still has all the electrical properties of "ordinary" silicon, meaning that it could be used as part of an electronic device. As a result, the operations observed were able to achieve a remarkable 99.99 percent accuracy."
