qBraid Announces qBraid OS for Operating Quantum Computing Services

Software weaves quantum processors together with CPUs and NVIDIA GPUs using NVIDIA CUDA-Q platform

BERLIN, Oct. 21, 2026 /PRNewswire/ -- NVIDIA GTC Berlin -- qBraid today introduced qBraid OS, software that quantum hardware providers and system operators can use to run their systems and make them available to users, whether as a commercial service or for internal use. qBraid OS manages access, scheduling and billing for a quantum processor, and runs it together with NVIDIA accelerated computing, on premises or in the cloud.

Companies building or operating quantum computers typically develop this software themselves, alongside the hardware. qBraid OS is based on the infrastructure qBraid has built and operated for its own agentic platform, which serves thousands of quantum developers and provides access to systems from 18 quantum hardware providers.

qBraid OS is designed to leverage NVIDIA accelerated computing alongside quantum processors through the NVIDIA CUDA-Q platform, to allow quantum error-correction decoding and classical processing during each quantum job. Because qBraid is a supported CUDA-Q provider, systems running qBraid OS can be made available to developers through CUDA-Q.

Key capabilities include:

• Connection through an existing processor interface or directly to a system's control electronics
• Combined scheduling of quantum processors and NVIDIA accelerated computing, including systems connected through NVIDIA NVQLink
• User management, reservations, usage metering and billing
• Setup and operation designed to be carried out with AI agents, within permissions set by the system's operator
• Access for developers through the qBraid SDK, qBraid's AI agents and NVIDIA CUDA-Q, using the same code they write for other qBraid hardware
• Defined integration points for compilers, optimizers, error-mitigation tools and resource-estimation services, so each needs to integrate only once

qBraid OS can be deployed wherever a quantum computer is installed, from a hardware company's own lab to a supercomputing center, where the processor runs alongside GPU and high-performance computing systems on premises.

"Companies building quantum computers should be able to spend their time on the hardware," said Kanav Setia, CEO of qBraid. "qBraid OS gives them the software we have built and run for our own platform, connected to NVIDIA accelerated computing, so their systems are ready for users sooner."

"Quantum processors and GPU supercomputers will become as easy to use together as CPUs and GPUs are today," said Sam Stanwyck, Director of Quantum Product at NVIDIA. "qBraid OS builds on NVIDIA CUDA-Q and NVQLink to help hardware providers offer their systems as services, giving developers and AI agents a consistent way to access quantum hardware and run unified workflows."
