Pre-Foundry Qubit Decision & Audit Platform: from cleanroom tolerances to cryogenic observables, before you fabricate

ZeroDec links junction process scatter to the full circuit Hamiltonian, propagated yield and tolerance specs, and element-resolved coherence budgets of flux qubits, fluxonium, kinemons and unimons, in seconds, with every metric provenance-tagged (derived, calibrated or open).

Circuit spectrum

Exact diagonalisation of 4-junction and capacitively shunted flux qubits, fluxonium, kinemons, unimons and rf-SQUIDs: f01, f12, anharmonicity, persistent current and flux sensitivity, with per-junction asymmetry and fabrication spreads.

Readout design

The full qubit-resonator capacitance network, a multilevel dispersive shift by exact diagonalisation, dressed-state tracking and Purcell decay, behind a dispersive-validity gate that blocks figures the physics does not support.

Coherence and fabrication tolerance

Decoherence channels labelled predicted, input, heuristic or blocked; sensitivity matrices and Monte-Carlo junction spreads; time-dependent anneal dynamics with an automatic convergence gate.

Physics Error Engine

An independent audit and fault-diagnosis layer on top of the solver. Pre-flight checks the model behind every number before fabrication (numerical convergence, dispersive readout validity, collisions, anharmonicity, thermal population, gate timing). Trust gives a claims ledger of which outputs the physics authorises. Post-flight compares measurements with the design and identifies which parameter drifted, or states that the data cannot decide. Validated by blind fault injection. REST API with a free trial key: zerodec.tech/error-engine.

Validated against published devices

Each literature device (Chang et al. 2022, Yan et al. 2016, Nguyen et al. 2019, Zhang et al. 2021, Somoroff et al. 2023, López-Núñez 2023) is run through the solver and compared with its published measurement. Independent predictions are reported separately from inputs and calibrations, misses included.
