Silicon Encoded Spin Qubits Achieve Universality

Показать описание

HRL Laboratories, LLC, has published the first demonstration of universal control of encoded spin qubits. This newly emerging approach to quantum computation uses a novel silicon-based qubit device architecture, fabricated in HRL’s Malibu cleanroom, to trap single electrons in quantum dots. Spins of three such single electrons host energy-degenerate qubit states, which are controlled by nearest-neighbor contact interactions that partially swap spin states with those of their neighbors.

This sounds amazing and revolutionary. However, I cannot hear any narration to explain the mechanisms. Am I missing that due to user error, or is there no voiceover to describe what's occurring?
