Open Quantum Public Compute runs through a network of QPU operators coordinated by qBitTensor Labs on Bittensor Subnet 48: Quantum Compute.
Most quantum cloud access routes you to a single vendor's hardware at that vendor's price. Open Quantum takes a different path. Our Public Compute tier is powered by a decentralized network of independent QPU operators, built by qBitTensor Labs on the Bittensor ecosystem.
Bittensor is an open-source platform dedicated to incentivized intelligence, made up of 128 different specialized subnets. qBitTensor Labs owns Subnet 48 (Quantum Compute), as well as Subnet 63 (Enigma). Subnet 48 is the undisputed leader in decentralized quantum compute, hosting the largest pool of real QPU capacity of its kind.
The Subnet 48 network coordinates many independent operators to bring real QPU capacity online. The network matches jobs to operators, verifies results, and rewards the operators who deliver reliable capacity. Instead of one supplier, you tap a growing pool of real hardware, the same QPUs from IonQ, Rigetti, IQM, and AQT, with the economics of the network working in your favor.
Many independent operators contribute real QPU capacity, so Public Compute is not tied to any single supplier.
Subnet 48 is the leading quantum network on Bittensor, matching your jobs to operators and rewarding reliable capacity so the network stays competitive and honest.
If one operator is busy or offline, the network routes around it. More operators means more resilience.
Each independent operator brings more QPU capacity onto the network, adding hardware options and redundancy.
Operators compete to run your jobs, and the network rewards those who deliver reliable, low-cost capacity.
Supplier competition drives price down. Your jobs get run on the network for half the price of going direct to a hardware vendor.
Lower cost means you run more experiments, which draws even more operators online.
“Until now, the only free quantum credits came locked to a single QPU. We're proud to partner with qBitTensor Labs to bring the market something truly one of a kind, free credits that transcend any QPU, free to start on real hardware.”
Bob Wold, CEO, Quantum Rings
Run your first job on Public Compute in minutes. Sign up for a free Open Quantum account, install the SDK, and submit a circuit. The qBitTensor Labs network handles the hardware underneath, so you get real QPU results at roughly half the cost of going direct.
$50 of Free Quantum Compute
Every new Open Quantum account includes $50 of free quantum compute credits, refreshed every 90 days. Put them straight to work on Public Compute and run on real hardware at no cost.
Quantum control software
Boulder Opal handles autonomous calibration, characterization, and error suppression, so a QUB system runs at high fidelity without a team of PhDs tuning gates by hand.
