Balance between information gain and reversibility in weak measurement
Yong Wook Cheong, Seung-Woo Lee
We derive a tight bound between the quality of estimating a quantum state by measurement and the success probability of undoing the measurement in arbitrary dimensional systems, wh…
Minimum Disturbance Measurement without Post-Selection
So-Young Baek, Yong Wook Cheong, Yoon-Ho Kim
We propose and demonstrate a linear optical device which deterministically performs optimal quantum measurement or minimum disturbance measurement on a single-photon polarization q…
Robustness of multiparty nonlocality to local decoherence
Sung Soon Jang, Yong Wook Cheong, Jaewan Kim +1
We investigate the robustness of multiparty nonlocality under local decoherence, acting independently and equally on each subsystems. To be specific, we consider an N-qubit GHZ sta…
A generalized structure of Bell inequalities for bipartite arbitrary dimensional systems
Seung-Woo Lee, Yong Wook Cheong, Jinhyoung Lee
We propose a generalized structure of Bell inequalities for arbitrary d-dimensional bipartite systems, which includes the existing two types of Bell inequalities introduced by Coll…
Entanglement purification for high dimensional multipartite systems
Yong Wook Cheong, Seung-Woo Lee, Jinhyoung Lee +1
We propose an entanglement purification protocol for high-dimensional multipartite systems. In the protocol we can select a subensemble in a pure generalized Greenberger-Horne-Zeil…
Cross-Kerr-based information transfer processes
Jinhyoung Lee, M. Paternostro, C. Ogden +3
The realization of nonclassical states is an important task for many applications of quantum information processing. Usually, properly tailored interactions, different from goal to…
