For the first time ever, researchers have measured the fidelity—that is, the accuracy—of two-qubit logic operations in silicon, with highly promising results that will enable scaling up to a full-scale quantum processor.
The research, carried out by Professor Andrew Dzurak's team in UNSW Engineering, was published today in the world-renowned journal Nature.
The experiments were performed by Wister Huang, a final-year Ph.D. student in Electrical Engineering, and Dr. Henry Yang, a senior research fellow at UNSW.
"All quantum computations can be made up of one-qubit operations and two-qubit operations—they're the central building blocks of quantum computing," says Professor Dzurak.
"Once you've got those, you can perform any computation you want—but the accuracy of both operations needs to be very high."
