Photon and mode capacity (photon_and_mode_capacity)up to 16 photons interfering in 32 time-binsvendor claim
Vendor claim
- Source
- Quantum latent distributions in deep generative models (arXiv:2508.19857) · published 2025-08-27
- Method
- VENDOR_UNSPECIFIED
- Notes
- From an ORCA-authored arXiv paper (all authors affiliated with ORCA Computing), Appendix B.3: 'It supports up to 16 photons interfering in 32 time-bins.' Secondary coverage cites '40 qumodes' for PT-2, but that figure was not found on orcacomputing.com or in any fetched primary source this session.

- Quantum latent distributions in deep generative models (arXiv:2508.19857) · published 2025-08-27
- Method
- VENDOR_UNSPECIFIED
- Notes
- ORCA-authored arXiv paper; photon source 'based on parametric downconversion' with 'two sequential optical delay lines of the same length'.

Input state type (input_state_type)non-Gaussian, photon-subtracted squeezed states (PT-1 used single photons)verified
Independently corroborated
- Source
- Benchmarking the ORCA PT-2 Boson Sampler using Minimum Dominating Set Problems (arXiv:2605.30935) · published 2026-05-29
- Method
- Third-party academic benchmark (Park, Stepney, D'Amico; University of York)
- Notes
- Quote: 'The PT-2 device samples from non-Gaussian, photon-subtracted squeezed states, rather than single photons as in the PT-1' and 'uses a photon-number resolving detector'. Also: 'The PT-2 device also has capability for running a time-bin interferometer with two loops.'

Third party benchmark result (third_party_benchmark_result)boson sampler outperformed by classical methods at tested parametersverified
Independently corroborated
- Source
- Benchmarking the ORCA PT-2 Boson Sampler using Minimum Dominating Set Problems (arXiv:2605.30935) · published 2026-05-29
- Method
- Minimum Dominating Set problems solved via Binary Bosonic Solver on physical PT-2 (single- and double-loop configurations)
- Notes
- Authors' quote: 'With the parameters used in this experiment, the boson sampler is outperformed by the classical methods, but we hypothesise that this is due to insufficient samples and iterations.' arXiv preprint, not confirmed peer-reviewed.

Qubit count (qubit_count_physical)not publicly disclosed
Not publicly disclosed — checked 2026-08-19
- Finding
- No public disclosure found. This is a recorded, dated finding — we do not substitute an estimate or borrow a figure from a sibling device.
- Sources queried
- orcacomputing.com PT-2 and PT-1 product pages (fetched, marketing-level only), PT-2 unveiling press release (fetched), ORCA-authored arXiv:2508.19857 (fetched), third-party arXiv:2605.30935 (fetched)
- Notes
- ORCA does not publish a gate-model qubit count; the machine is a boson sampler described in qumodes/time-bins. Secondary sources give '~90 qubits' or '40 qumodes' but no primary source states these.
Single-qubit gate quality (gate_fidelities_1q_2q)not publicly disclosed
Not publicly disclosed — checked 2026-08-19
- Finding
- No public disclosure found. This is a recorded, dated finding — we do not substitute an estimate or borrow a figure from a sibling device.
- Sources queried
- orcacomputing.com product pages and press release (fetched), arXiv:2508.19857, arXiv:2605.30935 (fetched)
- Notes
- Not a gate-model machine; no gate fidelity figures published anywhere checked.
Cloud access (cloud_access)not publicly disclosed
Not publicly disclosed — checked 2026-08-19
- Finding
- No public disclosure found. This is a recorded, dated finding — we do not substitute an estimate or borrow a figure from a sibling device.
- Sources queried
- Amazon Braket device list (fetched), orcacomputing.com homepage and PT-2 page (fetched)
- Notes
- Vendor homepage markets PT-2 as 'rack mounted and air-cooled for on-premises and cloud', but no public cloud platform listing was found (not on Amazon Braket per device list fetched 2026-08-19). Known deployments are on-premises sales: NQCC (UK) testbed Q1 2025, PSNC (Poland) hybrid platform.
Predecessor PT-1 (predecessor_PT-1)PT-1: single-photon time-bin interferometer; rack-mounted, room temperature, optical fibre components; optimised for hybrid quantum-classical machine learningvendor claim
Vendor claim
- Source
- ORCA PT-1 (product page)
- Method
- VENDOR_UNSPECIFIED
- Notes
- Vendor PT-1 page publishes no photon/mode counts ('lowest entry costs', 'the starting point of our roadmap'). PT-1 single-photon input confirmed by third-party arXiv:2605.30935.
