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

Announced: 13 November 2025 — iqm.tech, read 20 October 2026
Modality: Superconducting — iqm.tech, read 20 October 2026
Physical qubits: 150 qubits — iqm.tech, read 20 October 2026
Logical qubits: Not confirmed: IQM's product page says “Supports up to 5 high-quality logical qubits” (page: IQM Halocene), but the register requires a demonstrated logical-qubit count with the code and paper; the page does not provide that demonstration and paper.
Two-qubit gate fidelity: Not confirmed: The Halocene announcement prints “targeting 99.7% physical two-qubit gate fidelity” (page: IQM launches Halocene, a new quantum computer product line for error correction). This is a target, not a reported fidelity with a named statistic such as median, average, or best.
One-qubit gate fidelity: Not confirmed: No one-qubit gate fidelity for IQM Halocene is printed on the IQM Halocene product page or in the Halocene announcement.
