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 ...
A new quantum processor has pushed the lifetime of fragile quantum information to a regime that once looked out of reach for superconducting chips, keeping data stable around 15 times longer than ...
