Geometric quantum gates in liquid-state NMR based on a cancellation of dynamical phases
Yukihiro Ota, Yoshito Goto, Yasusi Kondo +1
A proposal for applying non-adiabatic geometric phases to quantum computing, called the double-loop method [S.-L. Zhu and Z. D. Wang, Phys. Rev. A {\bf 67}, 022319 (2003)], is demo…

Composite pulses in NMR as non-adiabatic geometric quantum gates
Yukihiro Ota, Yasusi Kondo
We show that some composite pulses widely employed in NMR experiments are regarded as non-adiabatic geometric quantum gates with Aharanov-Anandan phases. Thus, we reveal the presen…

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…
