Maneuvering measurement-coherence into measurement-entanglement
Ho-Joon Kim, Soojoon Lee
Quantum dynamics governs the transformation of static quantum resources, such as coherence and entanglement, in both quantum states and measurements. Prior studies have established…
Relation between Quantum Coherence and Quantum Entanglement in Quantum Measurements
Ho-Joon Kim, Soojoon Lee
Quantum measurement is a class of quantum channels that sends quantum states to classical states. We set up resource theories of quantum coherence and quantum entanglement for quan…
One-Shot Static Entanglement Cost of Bipartite Quantum Channels
Ho-Joon Kim, Soojoon Lee
We first investigate the one-shot static entanglement cost to simulate a bipartite quantum channel under the set of non-entangling channels. The lower bound on the static entanglem…
One-shot manipulation of entanglement for quantum channels
Ho-Joon Kim, Soojoon Lee, Ludovico Lami +1
We show that the dynamic resource theory of quantum entanglement can be formulated using the superchannel theory. In this formulation, we identify the separable channels and the cl…
Enhanced multipartite quantum correlations by non-Gaussian operations
Ho-Joon Kim, Jaewan Kim, Hyunchul Nha
We study how conditional photon operations can affect multipartite quantum correlations, specifically nonlocality and entanglement, of the continuous variable GHZ states. We find t…
Quantum linear amplifier enhanced by photon subtraction and addition
Ho-Joon Kim, Su-Yong Lee, Se-Wan Ji +1
A deterministic quantum amplifier inevitably adds noise to an amplified signal due to the uncertainty principle in quantum physics. We here investigate how a quantum-noise-limited…
Enhancing quantum entanglement for continuous variables by a coherent superposition of photon subtraction and addition
Su-Yong Lee, Se-Wan Ji, Ho-Joon Kim +1
We investigate how the entanglement properties of a two-mode state can be improved by performing a coherent superposition operation of photon subtraction and addition, proposed by…
