Implementation of holonomic quantum gates by an isospectral deformation of an Ising dimer chain
Yukihiro Ota, Masamitsu Bando, Yasusi Kondo +1
We exactly construct one- and two-qubit holonomic quantum gates in terms of isospectral deformations of an Ising model Hamiltonian. A single logical qubit is constructed out of two…
Decrease of entanglement by local operations in the Dür-Cirac method
Yukihiro Ota, Motoyuki Yoshida, Ichiro Ohba
One cannot always obtain information about entanglement by the Dür-Cirac (DC) method. The impracticality is attributed to the decrease of entanglement by local operations in the DC…
Attainable entanglement of unitary transformed thermal states in liquid-state nuclear magnetic resonance with the chemical shift
Yukihiro Ota, Shuji Mikami, Motoyuki Yoshida +1
Recently, Yu, Brown, and Chuang [Phys. Rev. A {\bf 71}, 032341 (2005)] investigated the entanglement attainable from unitary transformed thermal states in liquid-state nuclear magn…
