"synchronize 2 individual electrons to exploit their interaction... 2 single-electron sources triggered to ps accuracy. Single-electron detectors record every collision outcome... electron pair generated by 2 separated sources placed intersecting paths... infer electron trajectories from experimental data... flying electron can be used as an ultrafast sensor or switch, it also proves a mechanism to generate quantum entanglement—a key component of quantum computing
