Crate wai_quantum

Expand description

wai-quantum — a deterministic quantum stack in pure Rust.

Byte-exact circuit simulation (statevector, stabilizer, tensor-network MPS and sparse-Pauli backends), the operational layer around it (calibration, error mitigation, qLDPC decoding, noise learning, circuit-equivalence proofs, atom rearrangement), a phasor/interference ML layer, and signed energy-accounted receipts binding every stage.

No QPU, no cloud service, no vendor SDK, and no system libraries — pure Rust, so the same source runs natively, in the browser via wasm, and as a WASI component at the edge, producing byte-identical results and receipts on all three.

Everything is behind a feature; enable only what you use.

Modules§

gates: Gates as matrices, shared by the dense state vector and the tensor networks: any unitary on any qubits, and the standard ones by name.
quantum: Deterministic quantum-circuit simulation as transportable, receiptable content — wai.quantum.circuit (extensions/quantum-sim).
quantum_arch: Architecture-level ESTIMATION — wai.quantum.arch.
quantum_atom: Deterministic neutral-atom REARRANGEMENT — wai.quantum.rearrange (extensions/quantum-ops § Register preparation).
quantum_bptn: Tensor-network states on the hardware graph, evolved by simple update and read through belief-propagation environments (wai.quantum.bptn).
quantum_cal: Deterministic autonomous qubit CALIBRATION — wai.quantum.cal.rabi (extensions/quantum-ops § Calibration engines).
quantum_channel: Transport, done honestly: what a noisy channel does to a quantum state, and how you find out what arrived.
quantum_chem: Molecules by DMRG — wai.quantum.chem.
quantum_comm: Quantum communication and security: key distribution, and why eavesdropping on it is not a matter of being careful.
quantum_compile: Deterministic circuit COMPILATION + equivalence proof — wai.quantum.compile (extensions/quantum-ops § Compilation).
quantum_control: Deterministic FILTER-FUNCTION control + NOISE SPECTROSCOPY — wai.quantum.cal.spectroscopy + wai.quantum.cal.robust_ff (extensions/quantum-ops § Calibration, frequency domain).
quantum_dmrg: Ground states of spin chains by DMRG — wai.quantum.dmrg.
quantum_energy: The acquisition class of a quantum receipt’s joule figure — an optional, signed label (extensions/energy-measurement.md §2 and §2.8 in the WAI repository).
quantum_frame: Noisy Clifford circuits at QEC scale — wai.quantum.frame.
quantum_gbs: Gaussian boson sampling, exactly — wai.quantum.gbs.
quantum_info: Quantum information: mixed states, subsystems, and the measurements that separate quantum theory from any classical account of it.
quantum_kernel: Phasor-feature classifier — the quantum kernel, deployed (wai.quantum.kernel).
quantum_ldpc: qLDPC MEMORY at circuit level — wai.quantum.ldpc.
quantum_match: Exact minimum-weight perfect-matching decoding — wai.quantum.match.
quantum_mitigate: Deterministic quantum ERROR MITIGATION — wai.quantum.mitigate (extensions/quantum-ops § Mitigation).

quantum_noisy: Noisy circuits — wai.quantum.noisy.
quantum_nqs: Neural quantum states — wai.quantum.nqs.

The generative Born machine, the phasor kernel classifier, and the phasor bridge all reduce to the same three primitives — bind (elementwise phase add), bundle (superpose), and similarity (interference readout) — and this is the receipt that prices them.
