Аннотация:Schemes for measuring the presence or absence of interference depending on the entanglement or non-entanglement of the states of the initial biphoton field are proposed. In this case, the disappearance of interference in the scheme of the "which way?" has nothing to do with the direct impact of the meter on the measured system. All that is needed is information about the channel through which the particle passed. It is shown that entanglement suppresses one-photon interference, but not two-photon interference, which can be observed in a scheme of the Franson interference type. Calculations are presented that confirm the efficiency of the circuit solutions and the conclusions made in the work.
