Quobly, Entropica partner on fault-tolerant quantum push

Quobly and Entropica Labs have signed a strategic memorandum of understanding (MoU) in Singapore to collaborate on fault-tolerant quantum computing, combining the development of silicon-based quantum processors with a fault-tolerant software stack.

The agreement brings together France-based Quobly, which focuses on silicon quantum computing, and Entropica Labs, a quantum software company headquartered in Singapore. The collaboration begins at the earliest stages of system design, aligning hardware decisions with the requirements of error-correction and orchestration software.

The MoU was signed in Singapore by Maud Vinet, Chief Executive Officer of Quobly, and Tommaso Demarie, Chief Executive Officer of Entropica Labs, in the presence of representatives from the Singaporean and French innovation ecosystems.

For Quobly, the agreement is part of its expansion in Singapore. The company incorporated there in 2025 and has positioned the city-state as its regional hub for partnerships and deployment in Asia, while keeping core research, technology development, and industrial activities led from France and Europe.

Fault Tolerance Focus

The partnership centres on fault-tolerant quantum computing, which aims to keep computations reliable even when qubits and operations are noisy. The MoU establishes a framework to develop fault-tolerant quantum software tailored to Quobly's silicon quantum processor architecture.

A central area of work is expected to focus on compiler and optimisation technologies for fault-tolerant quantum error correction. This software translates algorithms into lower-level instructions for specific hardware and manages how error-correction routines are scheduled and executed within system constraints.

The work will be adapted to Quobly's silicon-based approach and linked to the "operational readiness" of future quantum systems in the Asia-Pacific region. The MoU also provides a basis for ongoing technical collaboration as both companies advance their roadmaps.

Hardware And Software

Under the agreement, Entropica Labs' software stack is positioned as a foundational layer for scalable silicon quantum systems. The approach emphasises close coordination between hardware development and error-correction software development.

This kind of coordination has become a recurring theme in quantum computing as organisations seek to move from laboratory prototypes to larger-scale systems. Simply adding more qubits does not resolve the reliability and control challenges that arise as systems scale. Fault-tolerant methods encode logical qubits into groups of physical qubits and apply error detection and correction during computation.

In practice, this increases demands on compilers, scheduling, and resource management and imposes constraints on how processor architectures are designed and operated. The collaboration reflects the need to align those choices early, rather than retrofit software after hardware decisions are fixed.

Regional Hub

Singapore has placed significant emphasis on advanced research and deep technology, including quantum programmes at universities and public research institutions, and companies have used it as a base for regional business development and partnerships. Quobly's plan to develop Singapore as a hub for partnerships and deployment in Asia fits that pattern.

The MoU is presented as part of cross-border cooperation between European and Asian quantum hubs. It also reflects a wider push across the sector to move beyond experimental devices towards scalable systems capable of longer computations with error correction.

Vinet linked the agreement to Quobly's work on scaling silicon quantum systems and its regional strategy.

"Partnering with Entropica Labs, a Singapore-based quantum software company, strengthens our ability to build scalable quantum systems by combining silicon hardware with fault-tolerant software," said Maud Vinet, CEO of Quobly. "Singapore plays a key role in our international strategy, and this agreement marks an important step in establishing our long-term presence in the region."

Demarie pointed to scaling and system-level reliability as key priorities.

"As silicon quantum processors scale, the central challenge shifts from qubit physics to system-level fault tolerance. Unlocking their full potential requires tightly integrated error-correction and orchestration software. Quobly's approach to silicon quantum computing represents one of the most promising paths toward scalable quantum systems. We look forward to working closely with Quobly to co-design the fault-tolerant infrastructure layer that turns scalable qubits into quantum computers, and bring silicon quantum systems to operational maturity," said Tommaso Demarie, CEO of Entropica Labs.

The MoU sets a framework for joint development of fault-tolerant software tailored to silicon processors, running alongside each company's existing development plans.
