We build the decoder layer that makes fault-tolerant quantum computing possible today.
Founded in 2021 in the NIST/JILA quantum corridor, QECSync is an independently operated software company working on the hardest problem in near-term quantum computing.
Founded in the quantum research capital of North America
QECSync was founded in 2021 in Boulder, Colorado — home to NIST, JILA, and one of the highest concentrations of quantum physics researchers in the world. The proximity to active quantum hardware groups was deliberate. We needed to hear directly from the engineers testing 20-qubit superconducting chips and running trapped-ion experiments to understand what the decoder layer actually needed to do in practice.
The founding insight was simple but underappreciated: every published surface-code decoder assumed a hardware-agnostic noise model. Real devices don't work that way. Every qubit has a different T1, T2, and gate fidelity. A decoder that isn't tuned to your device is leaving logical error suppression on the table.
QECSync remains independently operated. We have no venture capital obligations and no pressure to generalize before we've solved the specific problem in front of us. That independence is deliberate — it lets us stay on the hardest technical problems instead of pivoting to the easiest markets.
What QECSync is not: We do not build quantum hardware. We do not operate a quantum cloud service. We do not simulate quantum systems classically for research purposes. QECSync is software that runs on your hardware stack — a compiler and decoder layer, nothing more and nothing else.

How we work
Open to hardware diversity
No quantum hardware platform has won. We are hardware-agnostic by design — our compiler and decoder work with any topology that can implement surface code plaquette measurements. We don't bet on winners; we make any contender viable.
Research-first
Every claim we make about decoder accuracy, latency, and threshold performance is grounded in reproducible methodology and published theoretical foundations. We publish our benchmark methodology and welcome independent verification.
Practical fault tolerance
We don't wait for perfect qubits. The engineering problem is getting below-threshold logical error suppression on today's noisy hardware — and that's the exact problem QECSync is built to solve, right now.
