Google does not expose a public API endpoint for its quantum hardware. Access is handled through direct research partnerships with Google, not through any cloud marketplace or open account system. There is no programmatic way to query device status without being an approved partner.
Quantinuum real QPU hardware sits behind a paid tier starting at $125,000 per month. Access is genuinely restricted and not something that can be worked around without a direct commercial agreement with Quantinuum.
We track IBM Quantum via a free Open Plan account, which gives access to a limited set of devices. Full access requires a Pay-As-You-Go account, which requires a credit card. This is a personal student project, so coverage is limited to what is genuinely accessible for now.
IonQ publishes a completely open, unauthenticated public API at api.ionq.co/v0.3/backends that returns live queue and status data for all their systems. There is no API key, no account, and no cost. This is genuinely unusual in the quantum industry and lets us poll it directly every 3 minutes. Most other providers require authenticated API keys or restrict programmatic access entirely.
AWS Braket reports queue depth as a raw task count which is the number of jobs sitting in line ahead of yours. Azure Quantum instead exposes an estimated wait time in minutes based on historical job throughput. Neither metric is directly comparable to the other. A device with 10 AWS tasks could mean 10 minutes or 2 hours depending on how long each circuit takes to run.
Our OFFLINE status reflects what the provider API reports at the moment of polling. Some providers mark a device as unavailable during calibration windows while still allowing jobs to be queued for execution once calibration completes. There can also be a lag of up to 3 minutes between a device coming back online and our dashboard reflecting it.
Live status and queue depth poll every 3 minutes. The 24H chart reflects this raw data in near real-time. The 1W, 1M, and 1Y charts are rolled up once per day at 00:00 UTC. This is a deliberate tradeoff to stay within the free tier of our database infrastructure. For research or time-sensitive decisions, always cross-reference with the official provider status page.
No. QPUStatus is a fully independent project with no commercial relationship with any provider listed on this site. We do not receive funding, API keys, or preferential access from AWS, Microsoft Azure, or any other company. All data is sourced from publicly accessible API endpoints. Hardware names and trademarks remain the property of their respective owners.
