Quantum non-demolition (QND) modulation of quantum interference
نویسندگان
چکیده
We propose an experiment where quantum interference between two different paths is modulated by means of a QND measurement on one or both the arms of an interferometer. The QND measurement is achieved in a Kerr cell. We illustrate a scheme for the realisation of this experiment and discuss some further developments.

A general discussion is given for first-kind (FK) and quantum non-demolition (QND) measurements. The general conditions for these measurements are derived, including the most general one (called the weak condition), an intermediate one, and the strongest one. The weak condition indicates that we can realize a FK or QND measuring apparatus of wide classes of observables by allowing the apparatus...

متن کاملQuantum non-demolition measurement of photon-arrival using an atom-cavity system
A simple and efficient quantum non-demolition measurement (QND) scheme is proposed in which the arrival of a signal photon is detected without affecting the qubit state. The proposed QND scheme functions even if the ancillary photon is replaced with weak light composed of vacuum and one-photon states. Although the detection scheme is designed for entanglement sharing applications, it is also su...
متن کاملFast polarimetry system for the application to spin quantum non-demolition measurement
We report the development of a fast pulse polarimeter for the application to quantum non-demolition measurement of atomic spin (Spin QND). The developed system was tunable to the atomic resonance of ytterbium atom and has narrow laser linewidth suitable for spin QND. Using the developed polarimeter, we successfully demonstrated the measurement of the vacuum noise, with 10 to 10 photon number pe...
متن کاملExploiting the Quantum Zeno effect to beat photon loss in linear optical quantum information processors
We devise a new technique to enhance transmission of quantum information through linear optical quantum information processors. The idea is based on applying the Quantum Zeno effect to the process of photon absorption. By frequently monitoring the presence of the photon through a quantum non-demolition (QND) measurement the absorption is suppressed. Quantum information is encoded in the polariz...
