Quantum Computing

ZKSF, the Zero Kelvin Simulation Foundry, puts quantum computing in your pocket: certified simulation and real quantum hardware on demand, with no specialized infrastructure and no institutional access required.

Drag gates onto the wires to build a circuit, write one in OpenQASM, pick a ready-made one, upload your own circuit, or let the router choose an engine for you. Every result carries a documented accuracy statement, because an approximate answer without an error bar is an assertion, not a measurement.

REAL QUANTUM PROCESSORS

Eight QPUs from seven manufacturers across all four hardware technologies, at the provider's own rate with no markup:

• Rigetti Cepheus-1, 108 superconducting qubits

• IQM Emerald, 54 superconducting qubits

• IQM Garnet, 20 superconducting qubits

• IonQ Forte Enterprise 1, 36 trapped-ion qubits

• AQT IBEX Q1, 12 trapped-ion qubits

• QuEra Aquila, 256 neutral atoms

• Pasqal FRESNEL, 100 neutral atoms

• Quandela Belenos, 12 photonic qubits over 24 optical modes

The same OpenQASM circuit runs on any of the five gate machines. Neutral-atom hardware takes a pulse sequence and photonic hardware a linear-optics circuit, so those come ready to run. Every engine shows its rate before you pick it, and shot counts are held inside what each device accepts.

GPU AND TPU, BILLED BY THE SECOND

• NVIDIA 24 GB card, exact statevector to 30 qubits, $3 per GPU-hour

• NVIDIA 141 GB card, 31 to 32 qubits, $8 per GPU-hour

• Google Cloud TPU, neural quantum states to 40 spins, $0.95 per chip-hour

Jobs route to the right card on their own, and unused time is refunded.

TWENTY ENGINES, ONE APP

Device-noise preview with zero-noise error mitigation. Exact neutral-atom analog dynamics and exact photonic linear optics. Neural quantum state search for ground states beyond the area law, where tensor networks stop.

REAL WORLD APPLICATIONS, MEASURED

Seven industry templates to get you started, each with a real problem run on our quantum engines and again on the best classical solver available, both published side by side, including the many cases the classical method wins. Finance, chemistry, cryptography, space, traffic, logistics, manufacturing. 40 measured runs with their costs and certificate IDs, and the size at which each classical baseline stops being tractable.

FOURTEEN READY-MADE PROGRAMS

Tap and run, no typing: GHZ and Bell states, Grover search, QAOA MaxCut, VQE on H2, Bernstein-Vazirani, teleportation, Rydberg blockade, an antiferromagnetic chain, Hong-Ou-Mandel on the exact simulator and on Belenos hardware, Ising chains at 4 and 8 spins, and a Heisenberg chain.

CERTIFIED RESULTS

ZCC-v0.1 certifies simulation accuracy: a fast convergence check by default, and an opt-in measured bound for results you need to defend. ZHF-v0.1 certifies hardware fidelity against the exact ideal distribution. Every finished job exports a public certificate anyone can check with our open-source verifier, without an account and without going through us.

COST AND CONTROL

A free cost and feasibility estimate before you commit a penny. Circuits that would return an inconclusive answer are refused with a diagnostic saying why, and what would work instead. Track your credit, spend by tier and payment history, and manage or delete your account from your phone. Pure pay-per-use: no subscription, no minimum spend.
