Waveguide Quantum Electrodynamics
Engineering photon–emitter interactions in 1D—using a suite of tools ranging from photonic-crystal waveguides to quantum dots to ultracold atoms in optical lattices—is opening intriguing experimental and practical opportunities in quantum information science and technology.
Waveguide QED could open new application appoaches, as in this artist’s view of a two-photon pulsed nonlinear interaction mediated by a quantum emitter in a nanophotonic waveguide. [H. Le Jeannic et al., Nat. Phys. 18, 1191 (2022); reproduced with permission from Springer Nature]
