The quantum vendor sees mathematics. Never what it means.

ArcaQ runs portfolio, scheduling, routing, and ground-state optimization on real quantum hardware — while your business context is decrypted only inside an attested confidential enclave. Only the abstracted mathematics crosses to the quantum processor. Math leaves the enclave; meaning never does.

ArcaQ is the newest product on the ArcaKey confidential-compute platform, already in production across healthcare, legal, and finance. Confidential by architecture, not by promise.

The architecture

A quantum computer has to observe the circuit it runs. That is physics, not a vendor choice — so every commercial quantum-optimization service today shows the hardware vendor what you are optimizing. For institutional capital, the circuit is the asset: strategy parameters, position sheets, beneficiary allocations.

ArcaQ removes that compromise structurally. Your natural-language problem reaches the ArcaQ enclave over a post-quantum envelope; the edge tier forwards ciphertext and holds no key. Inside attested confidential compute, an in-enclave language model translates the problem into a Quadratic Unconstrained Binary Optimization (QUBO) matrix. Only that abstracted mathematical object — coefficients and a gate sequence — crosses the boundary to the quantum processor. The result returns by the same path and is interpreted back into business meaning using context that never left the enclave.

A 64-by-64 matrix of coefficients could encode a portfolio rebalance, a supply-chain route, or a molecular configuration — the mathematics is identical. The business meaning lives in how those coefficients were derived, and that derivation happens entirely inside attested compute. The vendor sees a circuit; it cannot reverse-engineer what the circuit represents.

Math leaves the enclave. Meaning never does.

How it works

Every problem runs through a template — portfolio rebalance, tax-aware allocation, M&A screening, real-estate mix, and more — with three ways to provide inputs: CSV upload, a structured form, or natural language. From there, two execution paths: validate on the simulator, then run on real quantum hardware when you're ready.

Behind that simple surface, every step of the request lifecycle is recorded with a post-quantum signature bound to attestation evidence:

1. 01

   Sealed submission

   Your problem is sealed in the browser under a post-quantum envelope and forwarded as ciphertext. It is decrypted only inside the attested enclave.

2. 02

   In-enclave translation

   An attested language model translates the problem into a QUBO matrix and circuit — entirely inside confidential compute. Reserve and Grand Reserve route this through Confidential Council for higher-confidence translation.

3. 03

   Your confirmation

   Every dispatch to real quantum hardware waits for your explicit confirmation. Simulator runs need none — iterate as much as you like.

4. 04

   Mathematics only crosses the boundary

   The QUBO coefficients and gate sequence — and nothing else from your request — leave the enclave to the quantum processor at IonQ or Rigetti.

5. 05

   Interpretation and signed delivery

   The result returns to the enclave, is interpreted in the context of your original problem (which never left), and is delivered over your sealed session. The audit entry closes with a signature binding every prior step.

Verifiable, not promised

Confidentiality that comes from architecture, not from a vendor's policy. Each guarantee is something you can check, not something you have to trust.

Tiers

Three tiers, plus an optional Concierge advisory overlay. Annual billing is the headline; Atelier and Reserve also offer a monthly option for single-cycle exploration.

• ·A “run” is a dispatch to real quantum hardware. Local simulator iteration is unlimited at every tier.
• ·ArcaKey Executive Vault customers can add ArcaQ Atelier at $7,000/yr — about 30% off standalone — and upgrade to Reserve or Grand Reserve at standalone pricing.
• ·Concierge advisory overlay: $5,000/yr, or $1,500–3,000 per session. Included at no cost with Grand Reserve. No ArcaKey staff member ever sees your data.

Where it's used

ArcaQ is built for combinatorial optimization where the input data is itself sensitive. The launch templates span finance, operations, energy, and R&D.

One platform, not a point tool

ArcaQ is one product on the ArcaKey confidential-compute platform. The same architecture — attested hardware, post-quantum transport, signed audit — runs your confidential AI workspace (ArcaKey AI), multi-model attested deliberation (Confidential Council), continuous compliance monitoring (CDM), and clinical dictation (ArcaVoice).

An organization that adopts ArcaQ is, by definition, the buyer for confidential AI and signed compliance evidence too. CDM can monitor your ArcaQ activity alongside your AI Vault on a single signed report — one defensibility surface across everything you run.

For institutional capital

ArcaQ is the family's highest-trust entry point for the most security-conscious buyers — quant funds, sovereign wealth, family offices. Grand Reserve deployments run on a dedicated, region-pinned enclave: deployable in your jurisdiction, the direct answer to data-residency requirements.

Request access

ArcaQ access opens by request. Tell us the problem class you optimize and the confidentiality requirements you operate under, and we will respond with tier fit and next steps. Reserve and Grand Reserve include a guided onboarding.

Confidential by default. Mutual NDA available before any technical disclosure.

ArcaQ performs combinatorial optimization on today's noisy intermediate-scale quantum hardware. It is not investment advice and executes no trades. Performance ranges shown on use-case pages are drawn from published academic and industry benchmarks for the relevant problem class, not from ArcaQ measurements; ArcaQ-specific results will be published after hardware validation. The confidentiality claim is precise: end-user business context is decrypted only inside attested compute, and the data leaving toward the quantum vendor is mathematical, not contextual. ArcaQ does not claim full quantum homomorphism or attestation of the quantum processor itself, neither of which is achievable on any platform today.
