Quobly has successfully demonstrated two-qubit gates and readout on a silicon spin qubit chip fabricated using standard 300mm FD-SOI infrastructure at STMicroelectronics. This milestone validates the feasibility of integrating quantum operations directly into existing semiconductor manufacturing lines, offering a scalable path toward high-qubit-count processors that avoids the cost and complexity constraints of superconducting or trapped-ion approaches.
Quobly’s QSOI chip shows two-qubit gates in standard factory

Quobly achieved two-qubit gates and readout on a single QSOI quantum chip, fabricated in STMicroelectronics’ 300mm facility.
Quobly has demonstrated key quantum operations, single-qubit gates, two-qubit gates, and qubit readout, on a single quantum chip fabricated within STMicroelectronics’ 300 mm manufacturing facilities in Crolles, France, the company says. This achievement marks a step toward scalable quantum computing by proving these operations are possible within a standard semiconductor production environment. The company’s QSOI technology combines silicon spin qubits with FD-SOI transistors, designed from the outset for industrial manufacturing and large-scale integration. “Having these three basic operations…
