题目：Racing classical computers with quantum boson-sampling machines
In this talk, I will report two routes towards experimental BosonSampling with many photons. We developed SPDC two-photon source with simultaneously a collection efficiency of ~70% and an indistinguishability of ~91% between independent photons. With this, we demonstrate genuine and distillable entanglement of ten photons under different pump power . Such a platform will provide enabling technologies for teleportation of multiple properties of photons  and efficient scattershot BosonSampling.
Self-assembled InGaAs QDs are in principle deterministic single-quantum emitters with near-unity quantum efficiency and fast decay rate. near-unity indistinguishability , and high extraction efficiency, all combined in a single device compatibly and simultaneously . Long streams of >1000 single photons separated by tens of microseconds maintain a >92% indistinguishability, which are shown to be near transform limit . The single photons are used for 3-, 4-, and 5-bosonsampling experiments, more than 24,000 times faster than all pre-vious experiments, and more than 10 times faster than through calculating the matrices permanents using the first electronic computer (ENIAC) and transistorized computer (TRADIC) in the human history .
Our architecture is feasible to be scaled up to a larger number of photons and with higher rate to race against increasingly advanced classical computers in the near term.
