Entanglement as an Observer-dependent Concept: an Application to Quantum Phase Transitions
In 1935 Einstein, Podolsky, and Rosen [1] published a Gedanken-experiment that still surprises us today [2]. Their main observation highlighted a key feature of quantum phenomena in which a pure state of a composite quantum system may cease to be determined by the states of its constituent subsystems. It is this non-classical behavior that Schrödinger later termed entanglement [3]. Entangled st...
متن کاملObserver Dependent Wavelet Image Compressor
♣ This work was supported by AGH Technical University grant no. 10.10.120.39 ABSTRACT The image compression by means of wavelet technique is considered in this paper. The proposed solution takes advantages of the current observer eye position rather than the image content. The noninvasive eye-pursuit system determines the zone of observer’s interest and sends the information back to the image c...
متن کاملOrientation-dependent entanglement lifetime in a squeezed atomic clock.
We study experimentally the application of a class of entangled states, squeezed spin states, to the improvement of atomic-clock precision. In the presence of anisotropic noise, the entanglement lifetime is strongly dependent on squeezing orientation. We measure the Allan deviation spectrum of a clock operated with a phase-squeezed input state. For averaging times up to 50 s the squeezed clock ...
متن کاملObservation of entanglement-dependent two-particle holonomic phase.
Holonomic phases--geometric and topological--have long been an intriguing aspect of physics. They are ubiquitous, ranging from observations in particle physics to applications in fault tolerant quantum computing. However, their exploration in particles sharing genuine quantum correlations lacks in observations. Here, we experimentally demonstrate the holonomic phase of two entangled photons evo...
متن کاملMacroscopic entanglement by entanglement swapping.
We present a scheme for entangling two micromechanical oscillators. The scheme exploits the quantum effects of radiation pressure and it is based on a novel application of entanglement swapping, where standard optical measurements are used to generate purely mechanical entanglement. The scheme is presented by first solving the general problem of entanglement swapping between arbitrary bipartite...
