Alice & Bob Accelerates Quantum Computing with NVIDIA NVQLink 

Insider Brief

• Alice & Bob announced a collaboration with NVIDIA on NVQLink, an open architecture launched at GTC Washington, D.C., that integrates quantum processing units (QPUs) with GPUs for real-time orchestration in fault-tolerant quantum computing.
• NVQLink enables GPU compilation, live decoding, and dynamic calibration across diverse qubit types, allowing deterministic, low-latency communication between control electronics and NVIDIA GPUs.
• The partnership expands on earlier joint work between the companies, including Alice & Bob’s Dynamiqs simulator built on NVIDIA’s CUDA-Q platform, to accelerate progress toward practical, industrial-scale quantum computing.

PRESS RELEASE — Alice & Bob, a global leader in the race for fault-tolerant quantum computing, today announced its collaboration on NVIDIA NVQLink, launched at GTC Washington, D.C. NVQLink is NVIDIA’s new open architecture that integrates quantum processing units (QPUs) with classical GPUs, delivering real-time orchestration for fault-tolerant quantum computing (FTQC) applications. 

NVQLink is designed to accelerate the development of logical qubits by enabling GPU compilation, live decoding, and dynamic calibration within a unified quantum-classical workflow. The platform supports diverse qubit modalities and provides deterministic, low-latency communication between control electronics and NVIDIA GPUs. NVQLink also marks the ready availability of accelerated computing to perform tasks that have previously remained limited to dedicated hardware such as ASICs or FPGAs. 

“We are thrilled to see NVIDIA’s NVQLink addressing the layers of the FTQC stack we’ve long considered critical: logical orchestration, decoding, and live calibration,” said Jérémie Guillaud, VP of Firmware at Alice & Bob. “This launch is a clear signal that fault-tolerant quantum computers, such as Alice & Bob’s QPUs, are about to reach industrial maturity.” 

This collaboration builds on the existing relationship between the two companies’ quantum software teams, from which products such as Dynamiqs – Alice & Bob’s high-performance QPU simulation tool powered by NVIDIA accelerated computing and integrated with the NVIDIA CUDA-Q platform – were developed. NVQLink enables better FTQC solutions, bringing the timelines for useful quantum computing forward. 

“Demand for hybrid quantum-classical systems is growing as researchers and developers seek tighter integration, lower latency, and a unified programming model to turn experimental qubits into practical, scalable compute for real-world workloads,” said Tim Costa, General Manager for Quantum at NVIDIA. “Alice & Bob are working with NVQLink and the CUDA-Q platform to provide the accelerated pathway needed to couple QPUs with GPUs and advance quantum computing capabilities.”
