Abstract :
We develop a novel integrated scheme for on-chip generation of Bell states, which allows simultaneous spatial filtering of pump photons. It is achieved through spontaneous parametric down-conversion in a system of nonlinear adiabatically coupled waveguides. Importantly, the adiabatic couplers maintain the purity of generated Bell states in a relatively fabrication-fault-tolerant way.
