Qubit count (physical qubit count)100+ physical qubits (current generation); 500+ (upcoming generation); qubit arrays of up to 1,600 sites demonstrated ('world's largest qubit array, comprising 1600 qubits' per Feb 2024 roadmap PR) qubits / sitesvendor claim
Vendor claim
- Method
- VENDOR_UNSPECIFIED
- Notes
- Roadmap PR dated 2024-02-08. The 1,600 figure is an array-size demonstration, not the qubit count of the shipping Sqale system (100+).

Two-qubit CZ gate fidelity (two-qubit CZ gate fidelity)Best demonstrated: 99.73% +/- 0.03% (August 2024). Current-generation system spec: 99.48% with post-selection, 98.8% raw. Upcoming generation target: 99.6% percentvendor claim
Vendor claim
- Method
- Not stated on the vendor page (benchmarking protocol not named)
- Aggregation
- Best-demonstrated vs current-system spec distinguished by vendor; post-selected vs raw distinguished; no median label
- Notes
- The headline 99.73% is the vendor's record achievement, not the routinely delivered system figure (99.48% post-selected / 98.8% raw).

Sqorpius naming clarification (Sqorpius naming clarification)Sqorpius is a program/initiative, not a machine: 'the next phase of Infleqtion's quantum computing program... dedicated to creating error-corrected logical qubits tailored for commercial applications'. The hardware platform is named Sqale.vendor claim
Vendor claim
- Source
- Infleqtion Unveils 5-year Quantum Computing Roadmap (Infleqtion press release) · published 2024-02-08
- Method
- VENDOR_UNSPECIFIED
- Notes
- Roadmap target: 100 logical qubits executing circuits of depth above 1 million within five years of the Feb 2024 announcement. The assignment's 'Infleqtion Sqorpius if real' resolves to: real as a program name; the device record is Sqale.
