A technical paper titled “Programmable Nonlinear Quantum Photonic Circuits” was revealed by researchers at Niels Bohr Institute, College of Copenhagen, College of Bristol, and Ruhr-Universitat Bochum.
Summary:
“The dearth of interactions between single photons prohibits direct nonlinear operations in quantum optical circuits, representing a central impediment in photonic quantum applied sciences. Right here, we display multi-mode nonlinear photonic circuits the place each linear and direct nonlinear operations may be programmed with excessive precision on the single-photon stage. Deterministic nonlinear interplay is realized with a tunable quantum dot embedded in a nanophotonic waveguide mediating interactions between particular person photons inside a temporal linear optical interferometer. We display the potential to reprogram the nonlinear photonic circuits and implement protocols the place sturdy nonlinearities are required, specifically for quantum simulation of anharmonic molecular dynamics, thereby showcasing the brand new key functionalities enabled by our expertise.”
