Infleqtion

In 2025, Infleqtion demonstrated a 16x16 neutral atom array - the largest reported array of its kind in the UK - as part of the SQALE project at the NQCC, marking a crucial step towards building fault-tolerant quantum processors. The company's commercial platform is built around a 1,600-qubit lattice, the largest neutral-atom array reported to date, achieving an entangling-gate fidelity of 99.73%. In September 2025, Infleqtion agreed to merge with Churchill Capital Corp X in a transaction valuing Infleqtion at a pre-money equity of $1.8 billion. In 2024, Infleqtion was contracted to develop a neutral atom quantum computing testbed for the UK's National Quantum Computing Centre (NQCC), installing the first neutral atom quantum computer at the NQCC in July 2024. The company unveiled the world's largest qubit array comprising 1600 qubits and a 5-year roadmap signaling progress towards delivering fault-tolerant quantum computers. Infleqtion's approach utilizes multiple atomic species within a single system, representing a novel strategy for enhancing performance.

2025 Developments: In September 2025, Infleqtion agreed to go public via $1.8 billion SPAC merger with Churchill Capital Corp X, generating over $540 million in gross proceeds. In June 2025, secured $100 million Series C from Glynn Capital, Counterpoint Global, S32, and SAIC. In June 2025, secured £2.2 million UK funding for Sqale neutral atom quantum computer at NQCC. In July 2025, announced $50 million Illinois partnership over 4 years to build utility-scale neutral atom quantum computer. In October 2025, partnered with Silicon Light Machines for MEMS technology integration
