    120-logical-qubit echo evolution

    Forward evolution, a perturbation and reverse evolution — a focused investigation of deep logical computation.

    Claim boundary
    This is a specific echo workload. It is not presented here as an identical reproduction of Google Willow’s workload or as a universal quantum-advantage benchmark.
    Evidence status in this website
    A versioned execution report is not attached to this website build. Runtime, speedup and independent-verification claims are intentionally not published in this card.

    Simon

    Finding a hidden period

    Oracle-based hidden-period computation and the relations needed to recover an encoded structure.

    Claim boundary
    The website does not infer exponential speedup or a physical-QPU result from the algorithm’s name. Those claims require a specified oracle, workload and equivalent-work comparison.
    Evidence status in this website
    The precise instance, oracle interface and evidence bundle need to accompany a public result report. No unverified period length or speedup metric is included here.

    QAOA2000

    A larger structured workload

    Taking structured Max-Cut research beyond the current 400-logical-qubit service platform.

    Claim boundary
    Research width is not a promise that arbitrary 2,000-qubit circuits are supported by the current cloud service. A returned cut is not automatically an optimality certificate.
    Evidence status in this website
    Attach the graph, workload version, returned witness, independent rescoring and runtime conditions before publishing detailed performance numbers. This build does not publish a timing claim.

    A route toward quantum chemistry

    Claim boundary
    A defined computational route or active-space model is not the same as a validated solution of the full molecule. This page makes no claim that FeMoco has been solved.

    Think beyond expanded circuits

    A program-representation and execution research direction for very large logical workloads.

    Claim boundary
    One billion gates is a roadmap target here, not a measured execution result. Planned, represented, committed and actually executed operations must be counted separately.
    Evidence status in this website
    No billion-gate execution evidence is asserted in this build. Future milestone reports should state the counting convention and measured work explicitly.

    Quantum Gear

    From circuits to useful functions

    Connecting application intent, operators, precision and selected outputs to a computational route.

    Claim boundary
    The application layer and the fundamental-physics research are related directions, not a claim that every proposed function or physical model is a finished product.
    Evidence status in this website
    Each implemented function or mathematical experiment needs its own execution contract and evidence. This page describes the research direction without claiming an established Theory of Everything.

Scope matters. Research, engineering milestones and development targets are labelled separately. Each note explains what is — and is not — being claimed.

More logical capacity. Larger programs. A higher-level way to express what computation should do.

QUANTUM GEAR × QPE × FUNDAMENTAL PHYSICS

What if computationbecame a laboratoryfor new ideas?

Quantum Gear connects application intent to computational functions. A parallel research direction explores structured operators, spectral models and discrete geometry through phase-estimation methods.

  1. 01

    You name a function, the operator it acts on, and the precision you need.

  2. 02

    Connects that intent to a computation: a representation, and a precision or resource contract.

  3. 03

    The computation is laid out as a defined route through circuits, and run.

  4. 04

    What comes back is the outputs you chose to measure.

QPE × Quantum Gear × fundamental physics

A computational language for exploring structured operators and spectral questions.

This research explores relationships among operator spectra, discrete structure, phase estimation and candidate mathematical constructions in fundamental physics. Quantum Gear is also an application-facing layer for connecting functions to execution routes.

Mathematical and computational research — not a claim of an experimentally established Theory of Everything.
