”A quantum computer developed by Google achieved "quantum supremacy" after taking 200 seconds to solve a complex problem that the company says would take a supercomputer 10,000 years to solve.

…scientists at Google described the achievement as an "important milestone" in quantum computing, one that demonstrates that the company's designs are "going in the right direction." Still, the success of Google's quantum computer, dubbed Sycamore, doesn't mean that we're all going to be switching to quantum computers anytime soon…

Sycamore achieved "quantum supremacy," which occurs when a quantum computer can do something that a traditional computer cannot. To pass this benchmark, Google engineers pit Sycamore against the world's leading supercomputer, Summit…

"We performed a fixed set of operations that entangles 53 qubits into a complex superposition state"…

But the specific nature of this task has led some to question the utility of quantum computers like Sycamore.
"One criticism we've heard a lot is that we cooked up this contrived benchmark problem—[Sycamore] doesn't do anything useful yet…[t]hat's why we like to compare it to a Sputnik moment. Sputnik didn't do much either. All it did was circle Earth. Yet it was the start of the Space Age.
