Testing Bell inequalities with photon-subtracted Gaussian states
Hyunseok Jeong
Recently, photon subtracted Gaussian states (PSGSs) were generated by several experimental groups. Those states were called "Schrödinger kittens" due to their similarities to super…
Quantum superpositions and entanglement of thermal states at high temperatures and their applications to quantum information processing
Hyunseok Jeong, Timothy C. Ralph
We study characteristics of superpositions and entanglement of thermal states at high temperatures and discuss their applications to quantum information processing. We introduce th…
Violation of Bell's inequality using classical measurements and non-linear local operations
Magdalena Stobińska, Hyunseok Jeong, Timothy C. Ralph
We find that Bell's inequality can be significantly violated (up to Tsirelson's bound) with two-mode entangled coherent states using only homodyne measurements. This requires Kerr…
Transfer of Nonclassical Properties from A Microscopic Superposition to Macroscopic Thermal States in The High Temperature Limit
Hyunseok Jeong, Timothy C. Ralph
We present several examples where prominent quantum properties are transferred from a microscopic superposition to thermal states at high temperatures. Our work is motivated by an…
