Quantum Elements, a Los Angeles-based quantum software start-up, has emerged from stealth and announced the launch of its Constellation platform, which is built with AI integration at its core. The company has secured funding from QDNL Participations and the USC Viterbi School of Engineering.
The Constellation platform uses agentic AI and natural language prompts to help develop large-scale simulation-driven machine learning models, generate code, and run quantum applications. Its proprietary simulation back-end also supports what the company claims is the largest and most advanced noisy-qubit simulator to date, allowing users to prototype quantum systems prior to purchasing hardware access. The platform’s ability to pause and analyze errors within the simulator is intended to help users optimize applications for specific hardware.
The company was co-founded by CEO Izhar Medalsy, Ph.D.; Chief Scientific Officer Prof. Daniel Lidar (University of Southern California); and Prof. Amir Yacoby (Harvard). Quantum Elements has already built partnerships with companies such as Amazon and Rigetti, and its tools are intended to support the development of enhanced error correction and reliable logical qubits.
Dr. Subodh Kulkarni, CEO of Rigetti Computing, commented that the company has leveraged the platform’s AI-powered tools in support of its engineering, noting Quantum Elements’ deep insights in modeling superconducting qubit systems to improve gate fidelity. Kris Kaczmarek, Investment Director at QDNL Participations, noted that they expect the platform to become a dominant tool for developing quantum applications.
