Highly nonclassical quantum states of light, characterized by Wigner functions with negative values, have been all-optically created so far only in a heralded fashion. In this case, the desired output emerges rarely and randomly from a quantum-state

Purpose: Pain catastrophizing scale (PCS) is useful to predict anxiety of patients before medical treatment. The aim of the study was to investigate the relationship between pre-operative PCS and the period of acute post-operative pain after orthogna

We propose an experimental scheme to generate, in a heralded fashion, arbitrary quantum superpositions of two-mode optical states with a fixed total photon number $n$ based on weakly squeezed two-mode squeezed state resources (obtained via weak param

We observe the Hong-Ou-Mandel interference via homodyne tomography on two photons extracted from two quantum memories.
A fundamental element of quantum information processing with photonic qubits is the nonclassical quantum interference between

On-Demand Release of a Heralded Quantum State from Concatenated Optical Cavities

Autor: Kenzo Makino, Akira Furusawa, Jun-ichi Yoshikawa

Publikováno v: Engineering the Atom-Photon Interaction ISBN: 9783319192307

We describe a concatenated-cavities system that is capable of creation, storage, and on-demand release of a heralded optical quantum state. Here, two optical cavities are concatenated, where one is a memory cavity to store a quantum state inside, and
