Quobly Brings Alloy Forge to qBraid for Silicon Quantum Development

Insider Brief

• Quobly and qBraid have made Quobly’s Alloy Forge silicon quantum development environment available through the qBraid cloud platform.
• Alloy Forge combines hardware-aware emulation, pulse-level simulation and realistic noise models to help developers test quantum applications before accessing Quobly hardware.
• The integration gives users access to Alloy Forge alongside more than 24 quantum computing technologies as Quobly prepares the commercial launch of Alloy Pioneer by the end of 2026.

PRESS RELEASE — Quobly, a French company developing silicon-based quantum computers, and qBraid, a quantum computing cloud service providing access to more than 24 quantum computers, today announced that Alloy Forge is now available on the qBraid platform, further expanding access to Quobly’s silicon quantum development environment as the company prepares the commercial launch of Alloy Pioneer, its first quantum computer, by the end of 2026.

Built to support the development and validation of quantum applications under realistic hardware constraints, Alloy Forge combines hardware-aware emulation, pulse-level simulation and cloud accessibility, enabling developers to prepare applications for future Quobly quantum systems before hardware becomes available.

Alloy Forge: a Realistic Silicon Quantum Development Environment

Alloy Forge is designed to help developers move beyond idealized quantum simulations by reproducing the practical behavior and constraints of silicon spin qubits 

Alloy Forge relies on SpinPulse, Quobly’s open-source pulse-level simulation framework, enabling fine-grained modeling of silicon spin qubit operations and native gate behavior.

The combined software stack enables users to:

• develop and validate quantum applications under realistic hardware constraints;
• test quantum circuits before access to physical quantum processors;
• prepare workflows compatible with future generations of Quobly silicon quantum systems. 

The emulation environment incorporates realistic noise models derived from Quobly’s research, including hardware imperfections and non-Markovian noise effects.

Expanding Access Through the qBraid Ecosystem

Available through qBraid’s cloud platform alongside more than 24 quantum computing technologies, Alloy Forge enables developers, researchers and industrial users to experiment with Quobly‘s silicon quantum environment using familiar cloud-based workflows.

The integration complements Quobly‘s growing cloud ecosystem and broadens international access to its software stack, enabling users to begin developing and validating applications today while preparing for execution on future Alloy Pioneer quantum systems.

As Quobly continues expanding access to its technologies, Alloy Forge will progressively become available across additional cloud and HPC environments supporting the company’s software and hardware roadmap.

Supporting Quobly’s commercial roadmap

Unlike standalone research simulators, Alloy Forge is designed as a persistent software layer that evolves alongside Quobly‘s hardware roadmap, supporting successive generations of silicon-based quantum computing systems.

Together, Alloy Forge and Alloy Pioneer form the first software and hardware offerings within Quobly‘s Alloy product family. Alloy Forge provides developers with a continuous development environment, while Alloy Pioneer, Quobly’s first quantum computing system, marks the first step in the company’s roadmap toward scalable, fault-tolerant quantum computing systems engineered for seamless integration into existing datacenter and high-performance computing (HPC) infrastructures.

Quobly plans to commercialize Alloy Pioneer by the end of 2026, with a roadmap extending toward large-scale fault-tolerant architectures targeting one million qubits by 2032.

“At Quobly, we are not only building quantum computers, but we are also building the software ecosystem that will enable their adoption”, said Maud Vinet, CEO and co-founder of Quobly. “Alloy Forge is the development environment for our Alloy product family. By giving developers early access to realistic silicon quantum behaviour through the qBraid platform, we enable them to start building applications today that will seamlessly transition to Alloy Pioneer and future generations of Quobly quantum computers.” 

“qBraid is committed to making advanced quantum technologies more accessible to developers and researchers,” said Ryan Hill, CTO at qBraid. “By bringing Alloy Forge to our platform, we are expanding access to realistic silicon quantum emulation technologies and enabling users to explore new approaches to quantum application development.”

This collaboration reflects a shared ambition to accelerate the emergence of an industrial quantum computing ecosystem where developers can progressively transition from simulation environments to production-grade quantum hardware through unified cloud platforms.
