Coherence (T1_T2_coherence_times)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
- aqt.eu IBEX Q1 product page including full specifications table (fetched raw HTML); aqt.eu PINE solution page; AQT QV-32768 announcement page
- Notes
- AQT publishes error rates/QV but no T1/T2 on its public product pages.
Readout (readout_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
- aqt.eu IBEX Q1 product page spec table (raw HTML), aqt.eu PINE page, AQT-AWS press release PDF
Gate duration (two_qubit_gate_duration)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
- aqt.eu IBEX Q1 product page spec table (raw HTML); AQT QV-32768 page (gives only system-level QV circuits/sec)
- Notes
- Only system-level throughput disclosed: 'Duty cycle >20000 circuits per hour (depending on circuit depth)', 'Max. gate count per circuit 2000' (body text elsewhere says 'accepts quantum circuits with up to 1000 gates' — internal inconsistency on the page).
