Partial Swapping , Unitarity and No - signalling

چکیده
Abstract: It is a well known fact that a quantum state |ψ(θ, φ)〉 is represented by a point on the Bloch sphere, characterized by two parameters θ and φ. In a recent work we already proved that it is impossible to partially swap these quantum parameters. Here in this work we will show that this impossibility theorem is consistent with principles like unitarity of quantum mechanics and no signalling principle. c © Electronic Journal of Theoretical Physics.

2 Proof of No - splitting theorem from three different
In this work, we show that 'splitting of quantum information' [6] is an impossible task from three different but consistent principles of unitarity of Quantum Mechanics, no-signalling condition and non increase of entanglement under Local Operation and Classical Communication.
متن کاملJoint measurement of spin and Tsirelson’s bound
No signalling condition by itself does not answer the question why quantum-mechanics violates Bell’s inequality by not more than 2 √ 2. Recently Buhrman and Massar [1] have given the answer by using unitarity and linearity of quantum-mechanics. We provide a simple answer to the same with the help of realistic joint measurement in quantum mechanics and Bell’s inequality which has been derived un...
متن کاملCausality, Joint measurement and Tsirelson’s bound
Tsirelson showed that 2 √ 2 is the maximum value that CHSH expression can take for quantumcorrelations [B. S. Tsirelson Lett. Math. Phys. 4, (1980) 93]. This bound simply follows from the algebra of observables. Recently by exploiting the physical structure of quantum mechanics like unitarity and linearity, Buhrman and Massar [H. Buhrman and S. Massar Phys. Rev. A 72, (2005) 052103] have establ...
متن کاملNo-splitting Theorem: Principles of Quantum Information
In the context of quantum information there arise a number of interesting questions regarding the domains of operations which are feasible in classical context to be applicable in quantum information domain or not. The criterion of feasibility and non feasibility of various physical processes in quantum regime creates a set of impossible operations[1-6]. This may be probably due to the linear s...
متن کاملUnitarity and Interfering Resonances in Ππ Scattering and in Pion Production
Additivity of Breit-Wigner phases has been proposed to describe interfering resonances in partial waves in ππ scattering. This assumption leads to an expression for partial wave amplitudes that involves products of Breit-Wigner amplitudes. We show that this expression is equivalent to a coherent sum of Breit-Wigner amplitudes with specific complex coefficients which depend on the resonance para...
