Maximum entanglement of quantum-dot systems with single excitation in the spin van der Waals model
A. Miranowicz, S. K. Ozdemir, M. Koashi +2
Time evolution of entanglement of N quantum dots is analyzed within the spin-1/2 van der Waals (or Lipkin-Meshkov-Glick) XY model. It is shown that, for a single dot initially exci…
Quantum-optical states in finite-dimensional Hilbert space. I. General formalism
Adam Miranowicz, Wieslaw Leonski, Nobuyuki Imoto
The interest in quantum-optical states confined in finite-dimensional Hilbert spaces has recently been stimulated by the progress in quantum computing, quantum-optical state prepar…
Teleportation cost and hybrid compression of quantum signals
Masato Koashi, Nobuyuki Imoto
The amount of entanglement necessary to teleport quantum states drawn from general ensemble is derived. The case of perfect transmission of individual states and that…
What is Possible Without Disturbing Partially Known Quantum States?
Masato Koashi, Nobuyuki Imoto
Consider a situation in which a quantum system is secretly prepared in a state chosen from the known set of states. We present a principle that gives a definite distinction between…
