// Architecture

Plumbing, not water.

EigenOS is the integration layer above your compiler, your QEC library, and your vendor SDK. It does not own qubits. It does not invent new modalities. It sits above seven reference layers and makes them interoperable, observable, and auditable.

The 7-layer reference stack

LL7
Application intent
Algorithm, workload, cost constraint. What you actually want to compute.
LL6
Logical circuit
EQL IR .‚· OpenQASM 3.0 .‚· Qiskit .‚· Cirq. The portable circuit representation.
LL5
QEC code
Surface .‚· color .‚· qLDPC .‚· bosonic. The error-suppression choice.
LL4
Decoder target
MWPM .‚· belief-propagation .‚· union-find. Converts syndromes to corrections.
LL3
Physical modality
Superconducting .‚· trapped-ion .‚· neutral-atom .‚· photonic .‚· NV .‚· spin.
LL2
Interconnect
Photon links .‚· microwave .‚· cryo-CMOS .‚· transduction. How distant qubits share state.
LL1
Control plane
Drift .‚· calibration .‚· feedback .‚· scheduling. Keeps the system alive.

EigenOS operates at every layer boundary .¢â‚¬â€ between L1 intent and L2 circuit, between L3 QEC and L4 decoder, between L5 modality and L6 interconnect, between L7 control and the operator. It is the wiring between the wires.

// Design principles

Six rules we hold ourselves to.

Complementary, not competitive

EigenOS doesn't replace Qiskit, Cirq, Stim, or vendor SDKs. It sits above them. Drop it in as one extra integration layer.

Reproducible, not magical

Every measurement carries a canonical hash. Every audit cites its inputs. No black boxes, no proprietary magic.

Audited, not advertised

T5.4 Claims Audit is a first-party capability. EigenOS audits other vendors' claims; we also audit our own.

Portable, not platform-locked

Same circuit, eight backends, one measurement schema. Switch vendors, swap fibers, fuse modalities .¢â‚¬â€ your workload stays the same.

Permanent, not fashion-driven

Post-FTQC, hardware consolidates. Interoperability, observability, and claim audit all stay. EigenOS becomes more valuable.

Open where it must be, closed where it should

EQL language reference, hardware registry, measurement schema: documented. Adapter code, decoder qualifications, audit verdicts: not free. We charge for engineering, not standards.

// Parent patent

P11 MMQCR .¢â‚¬â€ Multi-Modal Quantum Compilation Runtime

The architecture above is claimed in P11 MMQCR, the parent patent of the 32-patent EigenOS IP family. 11 continuations-in-part extend MMQCR into specific modalities and downstream processes.
