What Quantum Elements does
Quantum Elements is a Los Angeles-based quantum software company founded in 2023 that builds the Constellation platform, an AI-native development environment combining hardware-calibrated digital twin simulation with noise-aware quantum circuit design, automated calibration, and an AI-powered "Quantum Copilot" assistant. The platform targets quantum researchers, startups, academic institutions, and quantum hardware companies, enabling them to design, validate, and optimize quantum algorithms and error-correction protocols without direct physical hardware access. Its underlying technology includes what the company describes as the largest noisy-qubit simulator to date, a proprietary quantum Monte Carlo algorithm (published in Physical Review Letters with USC researchers), and integrations with IBM, Rigetti, AWS Braket, Quantum Machines, and NVIDIA infrastructure. The company has claimed several benchmark results, including 99.9% qubit fidelity in collaboration with Rigetti, 99% accuracy for Shor's algorithm on IBM processors, and the first demonstration of logical qubits and logical error suppression on IBM hardware.
The company generates revenue through a cloud-based SaaS subscription model with usage-based elements, distributed via a self-serve signup at constellation.quantumelements.ai plus a direct enterprise sales motion via "Request a Demo." Pricing tiers and contract values are not publicly disclosed. The customer base spans three segments — quantum researchers and startups (primary), academic institutions, and quantum hardware companies — with a go-to-market that combines product-led growth with enterprise field sales. Distribution is global in scope with documented operating geographies in the United States and Singapore, supported by a Westlake Village, California headquarters (2829 Townsgate Road, Suite 100).
Quantum Elements is privately held and venture-backed, with disclosed investors including QDNL Participations (now Ground State Ventures, lead), Quantacet, Firgun Ventures, R-Squared Ventures, and the USC Viterbi School of Engineering. Co-founders are CEO Izhar Medalsy, CSO Professor Daniel Lidar (USC), and Professor Amir Yacoby (Harvard), with Dr. Chad Rigetti (founder of Rigetti Computing) joining the board in November 2025. The company operates with 11–50 employees and emerged from stealth in fall 2024, publicly launching Constellation in October 2025.
