Open Architecture Quantum Computing Specification and Testbed

TreQ in the UK has secured a £1.65m grant to embark on an ambitious project aimed at advancing quantum computing technology. The focus of this endeavor is the development of an open architecture testbed known as the OAQ Testbed. This innovative platform will bring together two distinct quantum processors, each equipped with different control systems and software stacks, resulting in the creation of eight unique configurations.

At the core of the OAQ Testbed are the Novera 9qbit device from Rigetti in the US and the 5qbit Soprano from Quantware in the Netherlands. These processors will be complemented by control systems from Quantum Machines and QBlox, calibration tools from Q-CTRL and Qruise, and the ability to run a variety of software applications.

Located in Milton Park, Oxfordshire, TreQ will be responsible for designing, constructing, and operating the testbed. One of the key features of this facility is its capability to allow users to seamlessly switch between different component configurations in a matter of seconds, facilitating software testing in diverse contexts.

Looking ahead to the future of quantum computing, the project aims to establish an open specification for low-level quantum workflows. This specification will serve as a common interface bridging the gap between quantum software and hardware, accommodating various processor technologies, starting with superconducting and trapped ion qubits from Oxford Ionics. The goal is to enable modular compilation and smooth execution of quantum programs, fostering greater cohesion within the supply chain and promoting collaboration across the industry.

Building upon the success of the TreQ Compass SG25B, which integrated the Rigetti Novera processor with a Qblox modular control stack, QuantrolOx qubit automation platform, and a Bluefors Ultra-Compact LD dilution refrigerator, the OAQ Testbed represents a significant leap forward in quantum computing systems. Dr. Joseph Rahamim, the Director of Systems Engineering at TreQ and the project lead, emphasized the importance of this initiative in pushing the boundaries of quantum technology and fostering collaboration among multiple companies to drive innovation and accelerate development.
