QpiAI, an Indian startup, has launched a superconducting quantum processor foundry in Bengaluru, capable of fabricating chips with up to...
Yonsei Plans IBM Nighthawk Quantum Upgrade in November
Yonsei University’s Quantum Initiative plans to replace its current IBM quantum processing unit with the company’s Nighthawk chip in November,...
Physicists Turned Quantum Computing’s Worst Enemy Into a Way to Make Entanglement
Ask anyone building a quantum machine what they fear most and the answer is dissipation: the slow leak of energy...
D-Wave’s New Gate Keeps Its Qubits’ Errors Easy to Spot
Most qubits fail unnoticed. Something nudges the quantum state, the information corrupts, and the machine has no idea until error...
A Qubit That Lasts Longer, Because of What It’s Made Of
A superconducting qubit is a beautiful, fragile thing. It holds quantum information for a flicker, a fraction of a millisecond...
