Infleqtion

aid: infleqtion
name: Infleqtion
description: '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.'

  name: Superstaq
  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.
