Better Quantum Results.
One API Call Away.
Submit your quantum circuit, get corrected results in ~30 seconds. No circuit changes, no extra QPU time, no six-figure contract — up to 2.7× fidelity improvement starting at $199/month.
Works with the quantum stack you already use
Why Qubience
Better results. Zero extra cost.
90% of the error correction power at 1% of the cost. No six-figure contracts. Just four lines of code.
Zero QPU Overhead
Your QPU bill stays exactly the same. Other solutions add 3-17× extra hardware time. Qubience uses virtual phase corrections that cost nothing on the quantum processor.
One Call. Done.
Send your circuit. Get corrected results. ~30 seconds, one API call, no calibration steps, no PhD required.
4 Lines of Code
pip install. Import. Call. Done. Drops into your existing Qiskit workflow with zero circuit rewriting.
from qubience import correct

Built for Researchers,
Not Enterprises
$199/mo. No custom contracts, no sales calls, no six-month procurement cycles. Sign up and start correcting today.
Proven on Real Hardware
2.7× fidelity improvement measured on IBM ibm_fez. Not simulators. We publish every result, including where we don't improve.
See benchmarksWorks With Any Circuit
VQE, QAOA, quantum chemistry, combinatorial optimization. If your circuit runs on IBM hardware, Qubience makes it better.
Integrate in Minutes
Three steps. Four lines. Zero changes to your algorithm.
