The low-noise, high-gain properties needed for high-performance quantum computing can be realized in a microwave photonic circuit device called a Josephson traveling-wave parametric amplifier (JTWPA), ...
Back in 2019, Google made waves by claiming it had achieved what has been called “quantum supremacy”—the ability of a quantum computer to perform operations that would take a wildly impractical amount ...
Today D-Wave Systems announced the immediate availability of a lower-noise D-Wave 2000Q processor in the Leap quantum cloud service. Reflecting years of customer feedback, the lower-noise processor ...
