Probing the effects of interaction in Anderson localization using linear photonic lattices
Changhyoup Lee, Amit Rai, Changsuk Noh +1
We show how two-dimensional waveguide arrays can be used to probe the effect of on-site interaction on Anderson localization of two interacting bosons in one dimension. It is shown…
Increasing and decreasing entanglement characteristics for continuous variables by a local photon subtraction
Su-Yong Lee, Se-Wan Ji, Chang-Woo Lee
We investigate how the entanglement characteristics of a non-Gaussian entangled state are increased or decreased by a local photon subtraction operation. The non-Gaussian entangled…
Multi-setting Greenberger-Horne-Zeilinger theorem
Junghee Ryu, Changhyoup Lee, Zhi Yin +4
We present a generalized Greenberger-Horne-Zeilinger (GHZ) theorem, which involves more than two local measurement settings for some parties, and cannot be reduced to one with less…
A quantum speedup in machine learning: Finding a N-bit Boolean function for a classification
Seokwon Yoo, Jeongho Bang, Changhyoup Lee +1
We compare quantum and classical machines designed for learning an N-bit Boolean function in order to address how a quantum system improves the machine learning behavior. The machi…
Greenberger-Horne-Zeilinger theorem for N qudits
Junghee Ryu, Changhyoup Lee, Marek Zukowski +1
We generalize Greenberger-Horne-Zeilinger (GHZ) theorem to an arbitrary number of D-dimensional systems. Contrary to conventional approaches using compatible composite observables,…
Robust-to-loss entanglement generation using a quantum plasmonic nanoparticle array
Changhyoup Lee, Mark Tame, Changsuk Noh +4
We introduce a scheme for generating entanglement between two quantum dots using a plasmonic waveguide made from an array of metal nanoparticles. We show that the scheme is robust…
