Journal ArticleDOI
Violating the Leggett-Garg inequalities with classical light
TL;DR: In this article, it was shown that the Leggett-garg inequalities are violated by convex sums of coherent states, which is not a suitable class of descriptions for classical dynamics.
Journal ArticleDOI
Nonclassicality in phase space and nonclassical correlation
TL;DR: In this paper, the authors adopt the well-accepted definition of nonclassicality in the form of lack of well-defined positive Glauber-Sudarshan $P$ function describing the state.
Journal ArticleDOI
Quantum one-time tables for unconditionally secure qubit- commitment
TL;DR: This paper proposes a scheme for unconditionally secure qubit-commitment that is a quantum cryptographic primitive forbidden by the recently proven no-masking theorem in the standard model, and demonstrates an operational setting where neither maximally classically-correlated state nor maximally entangled state is more valuable resource.
Journal ArticleDOI
Continuous-variable phase estimation with unitary and random linear disturbance
TL;DR: In this article, the problem of continuous-variable quantum phase estimation in the presence of linear disturbance at the Hamiltonian level by means of Gaussian probe states is addressed, and the authors derive the optimal input Gaussian states at fixed energy, maximizing the quantum Fisher information over the squeezing angle and the squeezing energy fraction.
Journal ArticleDOI
Twist and teleportation analogy of the black hole final state
Doyeol Ahn,Myungshik Kim +1 more
TL;DR: In this article, the connection between the quantum teleportation and the black hole final state is studied taking into account the nontrivial spacetime geometry, and the twist operation is used for the generalized entanglement measurement and the final-state boundary conditions to obtain transfer theorems for black hole evaporation.
