Data Model for Registered Tangible Cultural Properties Using Linked Data

2020

National registered tangible cultural properties complement important cultural properties and are widely protected under less strict regulations. In recent years, it is expected that cultural properties will be used for local tourism and town planning. …

Generating Gottesman-Kitaev-Preskill qubit using a cross-Kerr interaction between a squeezed light and Fock states in optics

2021 · arXiv (Cornell University)

Gottesman-Kitaev-Preskill (GKP) qubit is a promising ingredient for fault-tolerant quantum computation (FTQC) in optical continuous variables due to its advantage of noise tolerance and scalability. However, one of the main problems in the preparation of …

Optical Waveform Engineering of Non-Gaussian States

2023

Toward the realization of quantum information processing (QIP), continuous-variable (CV) system is a promising candidate, where scalable quantum information processors are already demonstrated [1]. The next milestone is the demonstration of universality and fault-tolerance on …

Next Generation Optical Quantum State Synthesis: Observation of Fourfold Negativity in the Wigner Function

2024

An optical quantum state with fourfold Wigner negativity was generated without any loss correction. Generalized photon subtraction scheme, broadband squeezed light source, and high-temporal-resolution transition-edge sensor enabled generation rates of tens of counts per second.
