“…Effects in several microscopic and statistical systems were recently studied in [18], [19], [20], [21], [22]. Further possible applications in quantum information are proposed in [23], [24]. The collapse of quantum state due to the measurement was, again, considered in [25], the entanglement in a system chaotic in the classical limit was studied in [26].…”

A simplified one-dimensional model of measurement of the position of a quantum particle by two distant detectors is considered. Detectors are modelled by quantum particles bounded in potential wells with just two bound states, prepared in the excited states. Their de-excitation due to the short range interaction with the measured particle is the signal for the detection. In the approximations of short time or small coupling between the particle and the measuring apparatuses, the simultaneous detection of the particle by both detectors is suppressed. The results extend to other models with two-level detectors.
