Retrodictive fidelities for pure state postselectors [PDF]
, 2006 Two measures of fidelity are proposed for postselecting devices, the retrodictive conditional probability that the state in the measurement arm is the one indicated by the detectors, and the probability that the device produces the state that it would ...

Performing photonic nonlinear computations by linear operations in a high-dimensional space
Nanophotonics, 2023 As photonic linear computations are diverse and easy to realize while photonic nonlinear computations are relatively limited and difficult, we propose a novel way to perform photonic nonlinear computations by linear operations in a high-dimensional space,

Silicon-on-insulator photonic crystal miniature devices with slow light enhanced third-order nonlinearities [PDF]
, 2012 The effects of the slow-down factor on third-order nonlinear effects in silicon-on-insulator photonic crystal channel waveguides were investigated. In the slow light regime, with a group index equal to 99, these nonlinear effects are enhanced but the ...
