Infleqtion

Infleqtion is a Louisville/Boulder, Colorado quantum-technology company — formerly ColdQuanta — that builds neutral-atom quantum computers, precision atomic clocks, and quantum sensors for governments, corporations, and research institutions. Its computing portfolio spans Sqale (a full-stack, fault-tolerant neutral-atom quantum computer), Quantum Cores (ready-to-use neutral-atom systems for laboratories), and Superstaq, an open-source quantum software platform with proprietary cross-layer optimization that compiles Qiskit, Cirq, and OpenQASM circuits down to hardware-native operations and routes them across heterogeneous quantum backends. Infleqtion's sensing portfolio includes the Tiqker optical atomic clock, Quantum Spectrum (Rydberg atomic spectrum sensing), and inertial sensors for GPS-denied positioning. The company was founded in 2007 as ColdQuanta, rebranded to Infleqtion in November 2022 after absorbing the Super.tech quantum-software acquisition, and became Infleqtion, Inc. (NASDAQ: INFQ) in January 2026. Superstaq (qiskit-superstaq, cirq-superstaq, general-superstaq) is the only developer-facing public surface; the hardware and sensing businesses are sold via direct engagement and government contracts rather than a self-serve API.

Infleqtion publishes 1 API on the APIs.io network. Tagged areas include Quantum Computing, Quantum Software, Neutral Atom, Atomic Clocks, and Quantum Sensing.

Infleqtion’s developer surface includes documentation, engineering blog, YouTube channel, and 19 more developer resources.

  description: Superstaq is Infleqtion's open-source quantum software platform. Developers write circuits in Qiskit, Cirq,
    or OpenQASM, and Superstaq applies cross-layer compilation, dynamical-decoupling error mitigation, and hardware-native
    gate decomposition to deliver up to ~10x performance on benchmarks. Distributed as three pip packages — qiskit-superstaq,
    cirq-superstaq, and general-superstaq — backed by a hosted execution service that routes jobs across heterogeneous quantum
    backends. Apache 2.0 licensed client; the underlying REST service requires an Infleqtion API key obtained via request.
