Quantum Journal Club: Generating 3 qubit quantum circuits with neural networks
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...

Topological triply-degenerate points in ultracold atoms and photonic hyperbolic metamaterials
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...

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...

Experimental determination of nuclear magnetic octupole moment of 137Ba+ ion
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...
