Prototype quantum processor boasts record 99.9% qubit fidelity

Scientists in Finland say they have made inroads toward “fault-tolerant” quantum computing after achieving record-low error rates in a prototype quantum processor — potentially paving the way to more practical and stable quantum computers.

In a statement, researchers at IQM Quantum Computers said their technology had broken ground in two key areas: the accuracy of operations between qubits — the most basic units of quantum information — and the stability of qubits over time.
