Mixedness and teleportation
S. Bose, V. Vedral
We show that on exceeding a certain degree of mixedness (as quantified by the von Neumann entropy), entangled states become useless for teleporatation. By increasing the dimension…
A quantum holographic principle from decoherence
Sougato Bose, Anupam Mazumdar
We present a fully quantum version of the holographic principle in terms of quantum systems, subsystems, and their interactions. We use the concept of environment induced decoheren…
Proposal for teleportation of an atomic state via cavity decay
S. Bose, P. L. Knight, M. B. Plenio +1
We show how the state of an atom trapped in a cavity can be teleported to a second atom trapped in a distant cavity simply by detecting photon decays from the cavities. This is a r…
Entanglement quantification and purification in continuous variable systems
S. Parker, S. Bose, M. B. Plenio
We develop theoretical and numerical tools for the quantification of entanglement in systems with continuous degrees of freedom. Continuous variable entanglement swapping is introd…
