RIKEN Study Explores Quantum Interference Using Silicon with “More accessible temperatures”
Quantum interferometry demonstrated in silicon at more practical temperatures
Selected notes ~
+ Using a silicon-based transistor similar to those found in everyday electronics, RIKEN researchers have produced a functional quantum ‘qubit’—the quantum equivalent of bits used in conventional computers—that operates above the extremely low temperatures.typically needed to observe quantum interference effects
“I wanted to use a silicon device as a universal basis for exploring ubiquitous, material-independent quantum effects,” explains Ono. “Furthermore, our device is not just a laboratory device made using silicon material, but a practical device that actually forms part of a large-scale integrated circuit.”
+ By fabricating a simple three-terminal device that is similar to a general transistor using standard microfabrication techniques, RIKEN researchers could observe quantum interference effects of a single qubit while continuously varying the energy level of the qubit.
