Entanglement and Disentanglement, Probabilistic Interpretation of Statevectors, and Transformation between Intrinsic Frames of Reference
نویسنده
چکیده
We study a quantum theory based on two assumptions: In the intrinsic frame of reference of an isolated, macroscopic system, (i) the system has no global motion and is not entangled with any other system, (ii) time evolution of statevectors of systems outside the system satisfy Schrödinger equation. A process of collision-type interaction between a microscopic system and a macroscopic system is studied in an auxiliary frame of reference. In transforming the statevector of the two systems obtained in the auxiliary frame of reference to the intrinsic frame of reference of the macroscopic system, the above first assumption requires a discontinuous change of the statevector. A probabilistic interpretation is given to the statevector for the discontinuous change. For the microscopic system, the density matrix given in the theory here is equal to the reduced density matrix given in the usual quantum mechanics.

Use of integrated standards in today's economy is imperative to create efficient financial markets, improve resource allocation and reduce transaction costs. In the same vein, all countries must make a lot of effort to develop common standards. However, ethnic diversity in different parts of the world results in different interpretations and judgments from accounting standards and challenges a ...
متن کاملEntanglement versus Disentanglement: Quantum Cryptography
In alternative disentanglement based quantum cryptosystem, classical channel cannot be used when the system is protected by no-cloning principle. But for the similar security criterion , it is discussed that classical channel can be used in alternative entanglement based quantum cryptosystem. A prototype of conventional entanglement based cryptosystem is recovered from alternative entanglement ...

This research aimed to review the use of second-person reference in advertisement translation, work out the general rules, and provide guidance to translators. Using second-person reference is common in the advertising discourse. Addressing audiences directly involves their attention and in this way enhances their memorization of the advertised message. Second-person reference can be realized v...

We calculate the entanglement between a pair of polarization-entangled photon beams as a function of the reference frame, in a fully relativistic framework. We find the transformation law for helicity basis states and show that, while it is frequency independent, a Lorentz transformation on a momentum-helicity eigenstate produces a momentum-dependent phase. This phase leads to changes in the re...

Since the introduction of the paradox of Einstein, Podolsky, and Rosen @1# and Schrödinger’s cat @2#, the entanglement of quantum states, i.e., the ability of composite quantum systems to exhibit nonlocal correlations, has been one of the most fascinating consequences of the quantum formalism. Today the entanglement also serves as a basic resource of quantum information theory @3#, which is bas...
