Lithium Niobate Electro-Optic Photonic Processor for Variational Quantum Eigensolver. [PDF]

Adv Sci (Weinh)
An integrated lithium‐niobate‐on‐insulator ququart processor implements an electro‐optically controlled photonic variational quantum eigensolver using single photons encoded in four path modes. Bell‐basis‐emulating ququart projective measurements reduce measurement settings while achieving chemical‐accuracy‐level molecular‐energy estimation.
