CP measurement in Verifying Quantum Teleportation of Neutral Mesons
Yu Shi, Yue-Liang Wu · arXiv (Cornell University) · 2007
In a recently proposed quantum teleportation or entanglement swapping using neutral kaons, the process is verified by measuring the strangeness ratio of the particle to which the state is teleported, or the strangeness asymmetry of the two particles to which the entangled state is swapped. This proposal can also be similarly implemented in terms of other neutral pseudoscalar mesons, with the strangeness generalized to other flavor quantities. We show that one can complete the tests by CP measurement. This method is much simpler than using measurement in strong basis. Especially, it is rigorous, independent of whether CP is violated in weak decays.
