Entanglement of coherent states and decoherence

Radim Filip, Jaroslav Rehacek, Miloslav Dusek

A possibility to produce entangled superpositions of strong coherent states is discussed. A recent proposal by Howell and Yazell [Phys. Rev. A 62, 012102 (2000)] of a device which…

Entangled webs: Tight bound for symmetric sharing of entanglement

Masato Koashi, Vladimir Buzek, Nobuyuki Imoto

Quantum entanglement cannot be unlimitedly shared among arbitrary number of qubits. Larger the number of entangled pairs in an N-qubit system, smaller the degree of bi-partite enta…

Recycling of quantum information: Multiple observations of quantum clocks

Vladimir Buzek, Peter L. Knight, Nobuyuki Imoto

How much information about the original state preparation can be extracted from a quantum system which already has been measured? That is, how many independent (non-communicating)…

Optimal manipulations with qubits: Universal quantum entanglers

Vladimir Buzek, Mark Hillery

We analyze various scenarios for entangling two initially unentangled qubits. In particular, we propose an optimal universal entangler which entangles a qubit in unknown state $|Ψ>…
