Quobly Demonstrates Key Quantum Operations on 300 mm Silicon Chip

Insider Brief

• Quobly has demonstrated qubit readout, single-qubit gates and two-qubit gates on a single QSOI® chip fabricated through STMicroelectronics’ commercial 300 mm FD-SOI manufacturing process.
• The results provide an initial validation of Quobly’s technology transfer into an industrial semiconductor manufacturing environment and its approach to repeatable quantum processor fabrication.
• Quobly is using the results to advance its Alloy quantum computer roadmap, with Alloy Pioneer planned for cloud access by the end of 2026 and a longer-term target of one million qubits by 2032.

PRESS RELEASE — Quobly, a French quantum computing company developing  industrially scalable quantum computers based on silicon spin qubits, today announces new results  showing qubit readout, single-qubit gates and two-qubit gates on a single quantum chip fabricated on  its proprietary QSOI® technology. 

 The results were obtained on QSOI® devices fabricated in STMicroelectronics’ commercial 300 mm  manufacturing facilities in Crolles (Grenoble – France), using FD-SOI CMOS technology.  • This demonstrates that key quantum operations can be performed on devices manufactured  through an industrial semiconductor production process, providing an initial validation of the  technology path toward repeatable and scalable quantum processor manufacturing.
