The Startup Alice and Bob have been working on the cat qubit. Alice & Bob is a Paris-based quantum computing startup founded in 2020 by Théau Peronnin and Raphaël Lescanne, with a mission to build the ...

Using a powerful machine made up of 56 trapped-ion quantum bits, or qubits, researchers have achieved something once thought impossible. They have proven, for the first time, that a quantum computer ...

In a major step toward practical quantum computers, Princeton engineers have built a superconducting qubit that lasts three times longer than today’s best versions. “The real challenge, the thing that ...
