The Gaussian-Smoothed Wigner Function and Its Application to Precision Analysis
Hai-Woong Lee
We study a class of phase-space distribution functions that is generated from a Gaussian convolution of the Wigner distribution function. This class of functions represents the joi…
Generating arbitrary photon-number entangled states for continuous-variable quantum informatics
Su-Yong Lee, Jiyong Park, Hai-Woong Lee +1
We propose two experimental schemes that can produce an arbitrary photon-number entangled state (PNES) in a finite dimension. This class of entangled states naturally includes non-…
Searches on star graphs and equivalent oracle problems
Jaehak Lee, Hai-Woong Lee, Mark Hillery
We examine a search on a graph among a number of different kinds of objects (vertices), one of which we want to find. In a standard graph search, all of the vertices are the same,…
Finding structural anomalies in graphs by means of quantum walks
Edgar Feldman, Mark Hillery, Hai-Woong Lee +3
We explore the possibility of using quantum walks on graphs to find structural anomalies, such as extra edges or loops, on a graph. We focus our attention on star graphs, whose edg…
Quantum key distribution using vacuum-one-photon qubits: maximum number of transferable bits per particle
Su-Yong Lee, Se-Wan Ji, Hai-Woong Lee +2
Quantum key distribution schemes which employ encoding on vacuum-one-photon qubits are capable of transferring more information bits per particle than the standard schemes employin…
Nonclassicality generated by photon annihilation-then-creation and creation-then-annihilation operations
Su-Yong Lee, Jiyong Park, Se-Wan Ji +2
We examine nonclassical properties of the field states generated by applying the photon annihilation-then-creation operation (AC) and creation-then-annihilation operation (CA) to t…
