Qubit Tracker

Starling

Starling in the Qubit Tracker: every value read on the maker's own pages, with its day.

Announced: 10 June 2025 — www.ibm.com, read 16 October 2026
Modality: Superconducting — www.ibm.com, read 16 October 2026
Physical qubits: Not confirmed: IBM states a target of 200 logical qubits for Starling, but does not print a physical-qubit count for the system. The 200-qubit figure in the Technology Atlas is not identified there as a physical count.
Logical qubits: 200 qubits (target) — www.ibm.com, read 16 October 2026
Two-qubit gate fidelity: Not confirmed: The cited IBM Starling pages do not print a two-qubit gate fidelity for Starling.
One-qubit gate fidelity: Not confirmed: The cited IBM Starling pages do not print a one-qubit gate fidelity for Starling.
The maker’s own metric: Not confirmed: IBM describes 100 million gates as circuits Starling is intended to run; that is a circuit-capacity description, not a named system metric under the register's rules. The cited pages print no other named numerical system metric for Starling.
Access: Not confirmed: IBM says Starling is planned for 2029 and will be available to clients then, but the cited pages do not specify whether access will be cloud or on-premise. Starling is not yet listed as available, and the pages do not report it as a research-only system.
