Superstaq

Superstaq is Infleqtion's flagship quantum software platform that optimizes quantum program execution by tailoring to underlying hardware primitives, using proprietary cross-layer optimization techniques to deliver up to 10× performance improvements on real devices. The platform employs sophisticated compilation and noise mitigation techniques including dynamical decoupling, parametric gates, swap mirroring, phased microwave decompositions, approximate synthesis, and qutrits. Superstaq is hardware-agnostic, supporting superconducting qubits (AQT, IBM Quantum, Rigetti), trapped ions (QSCOUT), and neutral atoms (Infleqtion), with compatibility for Qiskit, Cirq, and OpenQASM. Infleqtion received a $1.15M Department of Energy SBIR Phase IIB grant to advance Superstaq—the first DOE SBIR Phase IIB award for quantum computing software. For benchmarks like Bernstein-Vazirani and Qubit Coupled Cluster chemistry methods, Superstaq improves execution performance by at least 10x compared to state-of-the-art compilers.
