To begin with, its users would now have access to its next-generation chip, called Apsen-M, with 40 qubits and improved performance. While that’s well below the qubit count achieved by IBM, […]

(credit: Rigetti Computing) Today, a quantum-computing startup has announced that it will take a significant departure in its designs for future quantum processors. Rather than building a monolithic processor as everyone else has, Rigetti Computing will build smaller collections of qubits […]
