Vendor claim
- Source
- IBM Quantum System Two: the era of quantum utility is here (IBM Quantum blog, Jay Gambetta) · published 2023-12-04
- Method
- VENDOR_UNSPECIFIED
- Notes
- Exact vendor wording: 'We have introduced IBM Condor, a 1,121 superconducting qubit quantum processor based on our cross-resonance gate technology. Condor pushes the limits of scale and yield in chip design with a 50% increase in qubit density, advances in qubit fabrication and laminate size, and includes over a mile of high-density cryogenic flex IO wiring within a single dilution refrigerator.'

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.

Availability (cloud_availability)never offered on IBM Quantum Platform; internal scale/yield research milestonevendor claim
Vendor claim
- Source
- IBM Quantum System Two: the era of quantum utility is here (IBM Quantum blog) · published 2023-12-04
- Method
- VENDOR_UNSPECIFIED
- Notes
- IBM frames Condor as 'an innovation milestone, solving scale and informing future hardware design'. Condor appears neither in the live fleet table (fetched 2026-08-19) nor among retired cloud QPUs at quantum.cloud.ibm.com/docs/en/guides/retired-qpus, consistent with it never having been a cloud service.
