Two paths to scalable quantum computing: Optical links between fridges and higher-temperature qubits

Superconducting qubits—bits of quantum information—have been widely considered a promising technology for moving quantum computing forward. But there's still much work to be done before they can be ...

A long-sought quantum computing milestone arrives as fermionic atom gates top 99% accuracy

Two independent research teams have each demonstrated collisional quantum gates using fermionic atoms: a long-sought ...
