7 Quantum Mechanics with Neutral Kaons ∗
We briefly illustrate a few tests of quantum mechanics which can be performed with entangled neutral kaon pairs at a Φ–factory. This includes a quantitative formulation of Bohr's complementarity principle, the quantum eraser phenomenon and various forms of Bell inequalities.
متن کاملPassive Quantum Erasure for Neutral Kaons
Quantum marking and quantum erasure are discussed for the neutral kaon system. Contrary to other two–level systems, strangeness and lifetime of a neutral kaon state can be alternatively measured via an “active” or a “passive” procedure. This offers new quantum erasure possibilities. In particular, the operation of a quantum eraser in the “delayed choice” mode is clearly illustrated.
متن کاملQuantum marking and quantum erasure for neutral kaons.
The neutral kaon system is shown to be suitable to discuss extensions and tests of Bohr's complementarity principle through the quantum marking and quantum erasure techniques suggested by Scully and Drühl [Phys. Rev. A 25, 2208 (1982)]]. Strangeness oscillations play the role of the traditional interference pattern linked to wavelike behavior, whereas the different propagation in free space of ...
متن کاملQuantum search algorithm as an open system
We study the quantum search algorithm as an open system. More specifically, we analyze the responses of that algorithm to an external monochromatic field, and to the decoherences introduced by the measurement process. We find that the search algorithm is robust with respect to many external interactions.
متن کاملNeutral Kaons in Random Media
The generalized dynamics describing the propagation of neutral kaons in randomly fluctuating media is derived and analyzed. It takes into account possible matter-induced effects leading to loss of phase coherence and dissipation. The study of selected neutral kaon observables indicates that these non-standard effects are amenable to a direct experimental analysis.
