Continuous-discrete entanglement: an example with non-relativistic particles
This article discusses entanglement between two subsystems, one with discrete degrees of freedom and the other with continuous degrees of freedom. The overlap integral between continuous variable wave functions emerges as an important parameter to characterize this kind entangle-ment. " Beam-like " entanglement and " shape-like " entanglement are contrasted. One example of this kind of entangle...
متن کاملDiscrete Spacetime and Relativistic Quantum Particles
We study a single quantum particle in discrete spacetime evolving in a causal way. We see that in the continuum limit any massless particle with a two dimensional internal degree of freedom obeys the Weyl equation, provided that we perform a simple relabeling of the coordinate axes or demand rotational symmetry in the continuum limit. It is surprising that this occurs regardless of the specific...
متن کاملLocalization of non-relativistic particles
This paper is a contribution to the problem of particle localization in non-relativistic Quantum Mechanics. Our main results will be (1) to formulate the problem of localization in terms of invariant subspaces of the Hilbert space, and (2) to show that the rigged Hilbert space incorporates particle localization in a natural manner. PACS numbers: 03.65.-w
متن کاملEntanglement swapping between discrete and continuous variables.
We experimentally realize "hybrid" entanglement swapping between discrete-variable (DV) and continuous-variable (CV) optical systems. DV two-mode entanglement as obtainable from a single photon split at a beam splitter is robustly transferred by means of efficient CV entanglement and operations, using sources of squeezed light and homodyne detections. The DV entanglement after the swapping is v...
متن کاملNon - relativistic classical mechanics for spinning particles ∗
[ψ ≡ ψγ, p̂ ≡ i~∂, and Ŝ ≡ i~(γγ − γγ)/4 represents the spin tensor operator]. The first term in the r.h.s. is associated with the translational motion of the CM; whilst, the non-Newtonian term in the r.h.s. is related to the existence of the spin, and describes the Zitterbewegung rotational motion. Analogous Gordon-like decompositions of the conserved currents can be written for spin-1 bosons a...
