Active and Passive Quantum Erasers 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. PACS number...

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 کامل7 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 کاملQuantitative Duality and Quantum Erasure for Neutral Kaons
The aim of this contribution is to illustrate two basic aspects of quantum mechanics applied to the neutral kaon system. We first describe a recent quantitative formulation of Bohr’s complementarity principle for free–space evolution of single kaons and entangled kaon pairs. We then show that the neutral kaon system is also suitable for an optimal demonstration of the “quantum eraser”, includin...
