In QOLO we use shutters mainly for switching between different input signals, such as probe laser and single photons, and for closing individual paths of complex interferometric setups. Typically, there are two methods how to achieve this goal based on
Theoretician’s beam splitters in The Big Bang Theory
Noiseless loss suppression in quantum optical communication
