Quobly announces key milestone for fault-tolerant quantum computing

The semiconductor industry has played a pivotal role in enabling classical computers to scale at cost; it has the same transformative potential for quantum computers, making them commercially scalable and cost competitive. Silicon spin qubits are excellent for achieving fault-tolerant, large-scale quantum computing, registering clock speeds in the µsec range, fidelity above 99% for one and two-qubit gate operations and incomparably small unit cell sizes (in the hundredths of 100nm²).

To capitalize on decades of semiconductor infrastructure investments, Quobly has adopted a fabless model. It focuses on FD-SOI, a commercially available CMOS technology manufactured by global leaders like STMicroelectronics, GlobalFoundries, and Samsung, as a platform for quantum computing.

Quobly's work, reported on December 9^th, 2024 at IEDM, addresses the critical challenges for scaling quantum systems. With CEA-Leti, CEA-IRIG and CNRS, Quobly has demonstrated the key building blocks for a quantum computer leveraging commercial FD-SOI:

Key achievements include:

This work positions FD-SOI as essential for scalable quantum processors and establishes Quobly as a leader in cost-efficient, fault-tolerant quantum computing. By co-integrating quantum and classical components on the same platform, Quobly is shaping scalable QSoC architectures.
