Silicon spin qubits usually lose accuracy when many qubits are driven in parallel, a barrier to scalable quantum processors. Writing in Nature Physics, RIKEN researchers traced the main error source to AC Stark shifts from shared microwave control signals. Their pairwise phase calibration protocol restored gate fidelities above 99.99% for up to three simultaneous qubits, and about 99.9% across all five, near fault-tolerant requirements.
Qilimanjaro Quantum Tech has completed a €19.6 million first close of its Series A round, led by Indra Group through IndraMind. SETT renewed its support with €9.6 million.
Researchers from Rutgers, IBM and collaborators demonstrated real-time quantum feedback control on a 156-qubit Heron processor, using up to 100 connected qubits. By alternately scrambling information and resetting qubits nearly 5,000 times each, they steered the system from chaos to an ordered state, revealing a sharp phase transition.
