Quobly Demonstrates Key Quantum Operations on 300 mm Silicon Chip
Quobly reported a demonstration of qubit readout, single-qubit gates, and two-qubit gates on a single chip fabricated with its QSOI technology. The devices were built on a 300 mm silicon wafer, which the company positions as an industrial-scale platform for silicon spin qubits.

If the demonstrated operations have usable fidelities, Quobly could move from single-device demonstrations to small multi-qubit arrays fabricated in a 300 mm CMOS-compatible flow within two years.
The result shows the required basic operations on the company's industrial 300 mm QSOI platform. The main remaining preconditions are published gate and readout fidelities, defect density, and integration with cryogenic control at scale.
