arXiv:2602.07191v1 Announce Type: new
Abstract: As quantum computing enters the cloud era, thousands of users must share access to a small number of quantum processors. Users need to wait minutes to days to start their jobs, which only takes a few seconds for execution. Current quantum cloud platforms employ a fair-share scheduler, as there is no way to multiplex a quantum computer among multiple programs at the same time, leaving many qubits idle and significantly under-utilizing the hardware. This imbalance between high user demand and scarce quantum resources has become a key barrier to scalable and cost-effective quantum computing.
We present HALO, the first quantum operating system design that supports fine-grained resource-sharing. HALO introduces two complementary mechanisms. First, a hardware-aware qubit-sharing algorithm that places shared helper qubits on regions of the quantum computer that minimize routing overhead and avoid cross-talk noise between different users' processes. Second, a shot-adaptive scheduler that allocates execution windows according to each job's sampling requirements, improving throughput and reducing latency. Together, these mechanisms transform the way quantum hardware is scheduled and achieve more fine-grained parallelism.
We evaluate HALO on the IBM Torino quantum computer on helper qubit intense benchmarks. Compared to state-of-the-art systems such as HyperQ, HALO improves overall hardware utilization by up to 2.44x, increasing throughput by 4.44x, and maintains fidelity loss within 33%, demonstrating the practicality of resource-sharing in quantum computing.

@cdarwin@c.imEvery modern digital technology
– from AI to quantum computing
– is based on foundational open source software building blocks.
Open source code is embedded in almost all products and services,
enabling economic growth and ensuring the resilience of our society and government.
While open source software has become the backbone of our digital infrastructure,
these essential components do not receive adequate support and investment.

@johnleonard@mastodon.socialA lot can be achieved 3 years. Famously the Empire State Building rose to its full 102 stories in less than 2 years; the Berlin Wall fell and Germany was officially reunified in less than three; and in a similar timeframe Wikipedia went from zero to a million articles.
Astonishingly, three years is about the time it takes a company to discover and replace its vulnerable cryptographic algorithms. Why?

Surely I can’t be the first person to note that quantum computing is in a state of superposition between existence and bogosity.
