Quantum-O · Architecture

One coherent stack.Five honest layers.

Quantum-O is not one breakthrough. It is a defined path from the monolithic die, through thermal isolation, through the classical host, into the runtime, and out to a managed cloud fallback. Each layer is engineered — and staged — separately.

Layer by layer

What is built, what is engineered, what is staged.

Each layer carries an explicit maturity label. We do not describe a roadmap deliverable as a shipping product.

Layer 01 · Quantum Core

Q-O v1.0 monolithic die · SiV spin cores in ²⁸Si

in-design
What it is

The Q-O v1.0 monolithic die. SiV colour-centre spin qubits in isotopically purified ²⁸Si, with Majorana boundary shielding and on-chip Si₃N₄ photonic routing.

How we're building it

Fabricated on a standard CMOS-compatible flow with post-implant SiV activation. Cryo-CMOS control tier is co-integrated on the same substrate.

Layer 02 · Foundational Physics

SiV centres, Majorana shielding, GDPE control

in-design
What it is

The foundational physics layer: SiV colour centres, Majorana boundary shielding, and the GDPE control formalism that governs gate synthesis and error suppression.

How we're building it

Characterised in published literature and reproduced in our simulation stack. The theoretical envelope is stable; the engineering task is translating it into a manufacturable control tier.

Layer 03 · Q-Ov1 Runtime

Open runtime · statevector engine · REST + CLI

prototyped
What it is

Q-Ov1, an open runtime that compiles quantum circuits to the chipset's native gate set, and the Quantum SDK that lets developers author those circuits today.

How we're building it

The runtime is live in software emulation against a local simulator and against a hosted node tier. The compiler targets a stable QASM subset.

Layer 04 · Quantum SDK

Circuit builder, algorithms, OpenQASM export

prototyped
What it is

The Quantum SDK — a browser-native circuit builder, algorithm library, and OpenQASM export path that lets developers author against the runtime today.

How we're building it

Shipping in the portal. Compiles to the same QASM subset the runtime consumes, so code written against the SDK runs unchanged on the hosted node tier.

Layer 05 · Enterprise & Cloud

Quantum Centres · hybrid orchestration

roadmap
What it is

Managed Quantum Centres that host physical chipsets and expose them as a hybrid compute service to enterprises whose host devices are not yet cryo-capable.

How we're building it

Standard cloud tenancy, queueing, and SLA. The Centre network is the near-term commercial vehicle; the on-device path is the long-term one.

Thermal budget

The load-bearing engineering problem.

Consumer-adjacent quantum only becomes credible if the cryogenic package shrinks. We say so explicitly.

Qubit plane
≤ 20 mK

Required for SiV spin coherence at gate-fidelity targets.

Control tier
~ 4 K

Cryo-CMOS band. Decouples from the qubit plane via passive shielding.

Host interface
300 K

Standard classical I/O to the operating system and network.

An architecture is only credible with a roadmap and filings behind it.
