A few years back, Google made waves when it claimed that some of its hardware had achieved quantum supremacy, performing operations that would be effectively impossible to simulate on a classical ...

A new microchip-sized device could dramatically accelerate the future of quantum computing. It controls laser frequencies with extreme precision while using far less power than today’s bulky systems.

Physicist Jay Gambetta, at IBM’s lab in Yorktown Heights, New York, explains how microwaves orchestrate a solution on a quantum chip: “Think of each qubit as a line in music. You’re creating notes.” ...
