Optimum unambiguous identification of d unknown pure qudit states
Ulrike Herzog, Janos A. Bergou
We address the problem of unambiguously identifying the state of a probe qudit with the state of one of d reference qudits. The reference states are assumed pure and linearly indep…
Creation of high-quality long-distance entanglement with flexible resources
Bing He, Yu-Hang Ren, Janos A. Bergou
We present a quantum repeater protocol that generates the elementary segments of entangled photons through the communication of qubus in coherent states. The input photons at the r…
Universal entangler with photon pairs in arbitrary states
Bing He, Yuhang Ren, Janos A. Bergou
We propose a setup that transforms a photon pair in arbitrary rank-four mixed state, which could also be unknown, to a Bell state. The setup involves two linear optical circuits pr…
Quantum searches on highly symmetric graphs
Daniel Reitzner, Mark Hillery, Edgar Feldman +1
We study scattering quantum walks on highly symmetric graphs and use the walks to solve search problems on these graphs. The particle making the walk resides on the edges of the gr…
Coherent states engineering with linear optics: Possible and impossible tasks
Bing He, János A. Bergou
The general transformation of the product of coherent states to the output state ( or ), which is realizable with linear opt…
