Information theoretic security -- from classical to quantum ---
Abstract: We treat the security when a given random number is partially leaked to a third party. In this case, application of hash functions generates secure key. In this talk, we treat what kinds of...

Continuous-variable quantum correlation and quantum communication: Beyond Gaussi
Quantum information protocols, originally envisioned for two-state (qubit) systems, have also been extended to continuous variables (CVs). It is usually held that Gaussian squeezed state is an essenti...

Cooperativity in spontaneous emission: Superradiance and its prospects
Superradiance is known as the enhancement of spontaneous radiation due to build-up of a collective dipole. Our work is to investigate whether superradiance plays any role in the otherwise extremely we...

Occam's Quantum Razor: How Quantum Mechanics can reduce the complexity of Classi
Mathematical models are an essential component of quantitative science. They generate predictions about the future, based on information available in the present. In the spirit of Occam's razor, simpl...
