The Min-entropy as a Resource for One-Shot Private State Transfer, Quantum Masking and State Transition
Seok Hyung Lie, Seongjeon Choi, Hyunseok Jeong
We give an operational meaning to the min-entropy of a quantum state as a resource measure for various interconnected tasks. In particular, we show that the min-entropy without smo…
Loss-tolerant transmission of multiphoton-qubit information via hybrid entanglement
Seongjeon Choi, Seok-Hyung Lee, Hyunseok Jeong
It was shown that using multiphoton qubits, a nearly deterministic Bell-state measurement can be performed with linear optics and on-off photodetectors [Phys. Rev. Lett. 114, 11360…
Negativity of quasiprobability distributions as a measure of nonclassicality
Kok Chuan Tan, Seongjeon Choi, Hyunseok Jeong
We demonstrate that the negative volume of any -paramatrized quasiprobability, including the Glauber-Sudashan -function, can be consistently defined and forms a continuous hi…
Nontrivial quantum observables can always be optimized via some form of coherence
Kok Chuan Tan, Seongjeon Choi, Hyunseok Jeong
In this paper we consider quantum resources required to maximize the mean values of any nontrivial quantum observable. We show that the task of maximizing the mean value of an obse…
Comment on "Quantifying quantum coherence with quantum Fisher information"
Hyukjoon Kwon, Kok Chuan Tan, Seongjeon Choi +1
We show that contrary to the claim in Sci. Rep. 7, 15492 (2017), the quantum Fisher information itself is not a valid coherence measure based on the resource theory of coherence be…
Coherence, Quantum Fisher Information, Superradiance and Entanglement are Interconvertible Resources
Kok Chuan Tan, Seongjeon Choi, Hyukjoon Kwon +1
We demonstrate that quantum Fisher information and superradiance can be formulated as coherence measures in accordance with the resource theory of coherence, thus establishing a di…
Quantum teleportation between a single-rail single-photon qubit and a coherent state qubit using hybrid entanglement under decoherence effects
Hyunseok Jeong, Seunglee Bae, Seongjeon Choi
We study quantum teleportation between two different types of optical qubits using hybrid entanglement as a quantum channel under decoherence effects. One type of qubit employs the…
