Volkswagen

Volkswagen is a German automotive company that pioneered quantum computing applications in the automotive industry, developing quantum algorithms for traffic flow optimization, route optimization, and autonomous vehicle coordination using D-Wave quantum annealing systems to optimize taxi routing in major cities, investigating quantum machine learning for predictive maintenance, battery optimization for electric vehicles, and supply chain management, collaborating with quantum computing companies to explore quantum advantages in manufacturing optimization, materials simulation for vehicle design, and logistics coordination across their global automotive production and distribution network.

Xanadu

Xanadu is a leading photonic quantum computing company that has pioneered the development of room-temperature, networkable quantum computers using squeezed light and integrated photonics. Founded in 2016, the company has developed the X-Series of photonic quantum computers, including the 216-mode Borealis system that demonstrated quantum computational advantage in Gaussian boson sampling by completing tasks in 36 microseconds that would take classical computers over 9,000 years. Xanadu’s unique approach uses continuous-variable quantum computing with photons, offering advantages in networking capabilities and room-temperature operation compared to other quantum technologies. The company is also the creator of PennyLane, an open-source quantum machine learning library that has become a standard tool for quantum-classical hybrid algorithms, used by researchers and developers worldwide. Xanadu operates Xanadu Quantum Cloud, providing programmatic access to their quantum hardware and simulators including Borealis through Amazon Braket. With significant funding and partnerships spanning academia, government, and industry, Xanadu is positioned at the forefront of photonic quantum computing and quantum machine learning applications.

Zapata Computing

Zapata Computing was a Harvard spinout founded in 2017 that specialized in quantum software and later pivoted to generative AI applications before going public via SPAC in April 2024, developing quantum-enhanced algorithms and AI solutions for enterprise customers in manufacturing, finance, and logistics, but ceased operations in October 2024 after struggling to achieve commercial success in the competitive AI market.
