Columbia Engineering researchers have developed HyperQ, a system enabling multiple users to simultaneously access a single quantum computer via isolated quantum virtual machines, addressing a critical bottleneck in quantum computing accessibility. Presented July 8th at the USENIX OSDI ’25 symposium, HyperQ reduces average user wait times by up to 40 times and increases program execution rates tenfold, demonstrably improving hardware utilization. This software layer, tested on IBM’s quantum computers, dynamically allocates resources and intelligently schedules jobs, allowing for concurrent operation without performance degradation and potentially enhancing computational accuracy by avoiding noisy chip regions. The technology promises significant cost savings for quantum cloud providers and accelerated research across sectors including drug discovery and materials science.
Quantum Computing’s Virtualisation Challenge
Columbia Engineering researchers have developed HyperQ, a system introducing quantum virtual machines (qVMs) to enable concurrent access to single quantum computers. This addresses a fundamental limitation of current quantum hardware – its inability to execute multiple programs simultaneously – which has historically resulted in researchers facing substantial delays and underutilisation of expensive resources. HyperQ functions as a software layer, or hypervisor, dividing a physical quantum computer into isolated qVMs, managed by a scheduler that dynamically allocates resources based on program requirements.
Initial results indicate HyperQ can reduce average user wait times by up to fortyfold, decreasing project completion from days to hours, and increase the number of executed quantum programs within a given timeframe by a factor of ten. Importantly, the researchers highlight that HyperQ operates with existing quantum programming tools, offering greater flexibility than previous approaches which required bespoke compilers and pre-defined program combinations.
Beyond enhanced efficiency, HyperQ’s intelligent scheduling capabilities can also improve computational accuracy. By directing sensitive workloads away from the noisiest areas of the quantum chip, the system mitigates the impact of decoherence – a major obstacle in quantum computation – potentially leading to more reliable results. This dynamic allocation of resources represents a substantial advancement in the field of quantum computing virtualization.
The implications of HyperQ extend to both quantum cloud providers and end-users. For companies such as IBM, Google, and Amazon, the technology offers a pathway to increase capacity and cost-effectiveness by serving a larger user base with existing infrastructure. For academic and industrial researchers, HyperQ promises faster access to critical quantum computing resources, accelerating progress in fields including drug discovery, materials science, and energy solutions. The team intends to expand HyperQ’s compatibility to encompass a wider range of quantum computing architectures, ensuring its continued relevance as the technology evolves.
HyperQ’s Operational Mechanics
HyperQ distinguishes itself from prior attempts at resource multiplexing through its dynamic operation and compatibility with existing quantum programming tools. Previous methodologies necessitated specialized compilers and pre-defined combinations of programs to function effectively; HyperQ, conversely, operates seamlessly with established workflows, offering substantially greater flexibility for real-world implementation.
The system’s operational efficacy stems from a software layer – a hypervisor – that partitions a physical quantum computer’s hardware into multiple, isolated quantum virtual machines (qVMs). A scheduler then manages these qVMs, akin to a sophisticated algorithm optimizing spatial arrangements, to maximize concurrent execution across different sections of the quantum processor. This approach to quantum computing virtualization allows multiple users to access and utilise the hardware simultaneously, without compromising individual program integrity.
Beyond improvements in throughput and reduced latency, HyperQ’s intelligent scheduling algorithms also address the inherent challenges of quantum hardware reliability. By strategically allocating workloads and diverting sensitive computations away from regions of the quantum chip prone to noise – a phenomenon known as decoherence – the system demonstrably enhances computational accuracy. This capability represents a significant advancement, mitigating a critical source of error in quantum computations.
The potential benefits extend beyond immediate gains in efficiency and accuracy. By enabling broader access to quantum computing resources, HyperQ accelerates progress across diverse scientific and industrial domains. Fields such as drug discovery, materials science, and energy solutions stand to gain significantly from the increased availability of quantum processing power, fostering innovation and potentially yielding transformative breakthroughs.
