Photon engineering for quantum information processing

Alfred B. U’Ren, Konrad Banaszek, Ian A. Walmsley

We study distinguishing information in the context of quantum interference involving more than one parametric downconversion (PDC) source and in the context of polarization-entangled photon pairs based on PDC. We arrive at specific design criteria for two-photon sources so that when used as part of complex optical systems, such as photon-based quantum information processing schemes, distinguishing information between the photons is eliminated guaranteeing high visibility interference. We propose practical techniques which lead to suitably engineered two-photon states that can be realistically implemented with available technology. Finally, we study an implementation of the nonlinear-sign shift (NS) logic gate with PDC sources and show the effect of distinguishing information on the performance of the gate.

Pure-State Photon-Pair Source with a Long Coherence Time for Large-Scale Quantum Information Processing

Bo Li, Yu-Huai Li, Yuan Wen Cao +2 more

This study presents an experimental technique to tackle technical obstacles in generating photon pairs in pure states with extended coherence times. Such photon sources are vital for large-scale quantum information processing. The authors successfully eliminate the frequency correlation of parametric photons using optimal filtering, which enables high-quality Hong-Ou-Mandel interference between two photon sources. This breakthrough has promising practical applications in quantum science and can facilitate engineering solutions for long-distance quantum interference.
