A Unity native plugin package wrapping Qulacs, a high-performance C++ quantum circuit simulator

Repository name: rqm-qiskit Mission: Build a clean, production-ready Python package that provides an SU(2)-native / quaternion-inspired interface on top of Qiskit, so users can describe 1-qubit quantum states and gates in rotation-first geometric language, then convert them into standard Qiskit circuits for simulation and IBM Quantum execution

Classiq Technologies is a Tel Aviv, Israel headquartered enterprise quantum software company founded in 2020 by Nir Minerbi (CEO), Amir Naveh (CPO), and Dr. Yehuda Naveh (CTO), positioning itself as a high-level quantum algorithm design platform that lets organizations build, scale, and deploy quantum algorithms across any hardware or simulator…

Quantinuum is an integrated quantum computing company formed by the 2021 merger of Honeywell Quantum Solutions and Cambridge Quantum. It builds trapped-ion (QCCD) quantum computers — the H1, H2, and Helios System Models — and develops the full software stack that runs on them: the Nexus cloud platform, the TKET quantum compiler, the InQuanto…
