Detecting entanglement with non-hermitian operators
Mark Hillery, Ho Trung Dung, Julien Niset
We derive several entanglement conditions employing non-hermitian operators. We start with two conditions that were derived previously for field mode operators, and use them to der…
Searching via walking: How to find a marked subgraph of a graph using quantum walks
Mark Hillery, Daniel Reitzner, Vladimir Buzek
We show how a quantum walk can be used to find a marked edge or a marked complete subgraph of a complete graph. We employ a version of a quantum walk, the scattering walk, which le…
Processing multi-photon state through operation on single photon: methods and applications
Qing Lin, Bing He, János A. Bergou +1
Multi-photon states are widely applied in quantum information technology. By the methods presented in this paper, the structure of a multi-photon state in the form of multiple sing…
Quantum key distribution using vacuum-one-photon qubits: maximum number of transferable bits per particle
Su-Yong Lee, Se-Wan Ji, Hai-Woong Lee +2
Quantum key distribution schemes which employ encoding on vacuum-one-photon qubits are capable of transferring more information bits per particle than the standard schemes employin…
Quantum Machines
Mark Hillery, Vladimir Buzek
We discuss quantum information processing machines. We start with single purpose machines that either redistribute quantum information or identify quantum states. We then move on t…
Scheme for generating coherent state superpositions with realistic cross-Kerr nonlinearity
Bing He, Mustansar Nadeem, János A. Bergou
We present a simple scheme using two identical cross-phase modulation processes in decoherence environment to generate superpositions of two coherent states with the opposite phase…
