Abstract: A new method for compiling quantum algorithms is proposed and tested for a three qubit system. The proposed method is to decompose a a unitary matrix U, into a product of simpler Uj via a n...
Abstract: Control over quantum dynamics of open systems is one of the central challenges in quantum science and engineering. Coherent optical techniques, such as coherent population trapping involvin...
Abstract: Topological states of matter provide a fertile ground for discovering new quasiparticles in condensed matter physics, such as Weyl and Dirac fermions, which were originally predicted in hig...
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...
Abstract: Trapped ions and cold atoms which are highly controllable offer us the most reliable and scalable quantum simulators. In this talk I will discuss firstly how to use trapped ions interacting...
Abstract: We have performed precision measurements of the hyperfine intervals of the 5D3/2 and 5D5/2 manifolds of a single trapped ion, 137Ba+. We have used rf spectroscopy to measure the hyperfine i...
