Physical mode count (physical_mode_count)216 squeezed modes (qumodes)vendor claim
Vendor claim
- Source
- Quantum computational advantage with a programmable photonic processor (Nature 606, 75-81) · published 2022-06-01
- Method
- VENDOR_UNSPECIFIED
- Notes
- Peer-reviewed but vendor-authored (Madsen et al., Xanadu). Corroborated by AWS Braket announcement describing 'the 216-qumode Borealis device'. Not gate-model qubits.

Two-qubit gate quality (two_qubit_gate_fidelity)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
- Nature 2022 paper (fetched), AWS Braket Borealis announcement (fetched), xanadu.ai blog (page JS-rendered, content not retrievable)
- Notes
- Not applicable: Borealis is a GBS sampler, not a gate-model machine. AWS states it 'is not a universal quantum computer... but rather implements a specific protocol known as Gaussian Boson Sampling (GBS)'.
Coherence (coherence_times_T1_T2)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
- Nature 2022 paper (fetched), AWS Braket announcement (fetched)
- Notes
- Not applicable to a single-pass photonic sampling machine; no coherence-time figures published.
Availability (availability_status)retired from public cloudverified
Independently corroborated
- Method
- Absence from Amazon Braket's current quantum-hardware provider list, checked 2026-08-19 (providers listed: AQT, IonQ, IQM, QuEra, Rigetti; 'Xanadu and Borealis are not listed')
- Notes
- Secondary sources report retirement from Braket around mid-2023, but no primary page stating the retirement date was found this session.
