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…
Single-photon logic gates using minimal resources
Qing Lin, Bing He
We present a simple architecture for deterministic quantum circuits operating on single photon qubits. Few resources are necessary to implement two elementary gates and can be recy…
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…
Creation of perfect long-distance quantum communication channel
Bing He, Yuhang Ren, Janos A. Bergou
This paper has been withdrawn by the authors, due a oversimplified decoherence model. It will be substituted by a new work.
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…
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…
