Quantum Elements is a US-based quantum software company developing an AI-native platform designed to make fault-tolerant quantum computing faster, cheaper, and more accessible. Co-founded in 2023 by CEO Dr. Izhar Medalsy, Chief Scientific Officer Prof. Daniel Lidar of USC, and Prof. Amir Yacoby of Harvard, the company emerged from stealth in October 2025 with backing from QDNL Participations and the USC Viterbi School of Engineering.

The company's Constellation platform integrates agentic AI, natural language prompts, and a proprietary simulation back-end to help users develop, debug, and run quantum applications across sectors including pharmaceuticals, energy, and finance. Its noisy-qubit simulator allows researchers and developers to prototype quantum systems and optimise code before committing to hardware access, lowering financial barriers for startups and academic users alike.

Headquartered in the Los Angeles area, Quantum Elements has established commercial partnerships with Amazon and Rigetti, alongside academic collaborations with USC and UCLA. The company is positioning Constellation as foundational software for the development of enhanced error correction techniques and reliable logical qubits, with the broader aim of accelerating the path from quantum prototype to real-world application.
