TECHNOLOGY & ACCESS

What it does. Where it fits.

Photonic measurement-based quantum computing

Who should look closer

Researchers examining photonic architectures, optical loss and the engineering needed for fault tolerance.

QubitWire’s editorial assessment of practical fit.

Hardware access not verified

Xanadu has retired its public Quantum Cloud. The reviewed sources do not establish an available Aurora execution service; existing cloud-client examples are historical.

DOCUMENTED EVIDENCE

What has been demonstrated

Aurora demonstrated linked photonic modules and real-time decoding in a scale model. The paper identifies optical loss as a remaining barrier to fault-tolerant performance.

What remains unresolved

Aurora is not an operational universal fault-tolerant computer. Archived Strawberry Fields examples should not be read as current access instructions.

The next question to watch

Can the next integrated system meet its loss budget and support sustained logical operations through a documented access program?

A research question, not a promised milestone.

Sources & evidence

  1. Scaling and networking a modular photonic quantum computerpaper · 22 Jan 2025

    Xanadu researchers report a 35-chip Aurora scale model with 12 physical qubit modes per cycle and real-time repetition-code decoding. Optical losses remain above the requirements for fault tolerance.

  2. Xanadu Cloud Client — retirement noticetechnical · Publication date not stated

    The official repository states that Xanadu Quantum Cloud is no longer available. The repository was archived on January 16, 2026.

  3. Photonics — Xanaduofficial · Publication date not stated

    Describes development of manufacturable modules for measurement-based photonic quantum computing and links to the Aurora research. These are development plans, not evidence of public hardware access.

  4. Strawberry Fields repositorytechnical · Publication date not stated

    Provides photonic-circuit simulation resources, but the repository is archived. Historical execution examples do not establish a currently operating cloud service.
