Broken Symmetries in the Entanglement of Formation
We compare some recent computations of the entanglement of formation in quantum information theory and of the entropy of a subalgebra in quantum ergodic theory. Both notions require optimization over decompositions of quantum states. We show that both functionals are strongly related for some highly symmetric density matrices. Indeed, for certain interesting regions the entanglement of formatio...
متن کاملTeleportation of entanglement over 143 km.
As a direct consequence of the no-cloning theorem, the deterministic amplification as in classical communication is impossible for unknown quantum states. This calls for more advanced techniques in a future global quantum network, e.g., for cloud quantum computing. A unique solution is the teleportation of an entangled state, i.e., entanglement swapping, representing the central resource to rel...
متن کاملHeegaard Floer homology of broken fibrations over the circle
This article is the first in a series where we investigate the relations between Perutz’s Lagrangian matching invariants and Ozsváth-Szabó’s Heegaard Floer invariants of three and four manifolds. In this paper, we deal with the purely Heegaard Floer theoretical side of this programme and prove an isomorphism of 3–manifold invariants for certain spinc structures where the groups involved can be ...
متن کاملBroken heart: Broken mind.
The increased frequency of sudden cardiac death after earthquakes and bombings has long proposed that emotional distress plays a role in acute coronary syndromes and arrhythmias. Since the 1960s, several controlled, prospective, epidemiological studies have reported emotional distress as a major risk factor for the onset and worsening of coronary heart disease (CHD) [1]. The Interheart study, a...
متن کاملDont Breathe and Drive? Pollutants Lurk inside Vehicles
The ability of human immunodeficiency virus type 1 (HIV-1) to develop high levels of genetic diversity, and thereby acquire mutations to escape immune pressures, contributes to the difficulties in producing a vaccine. Possibly no single HIV-1 sequence can induce sufficiently broad immunity to protect against a wide variety of infectious strains, or block mutational escape pathways available to ...
