A switchable controlled-NOT gate in a spin-chain NMR quantum computer
Atsushi Goto, Tadashi Shimizu, Kenjiro Hashi +1
A method of switching a controlled-NOT gate in a solid-stae NMR quantum computer is presented. Qubits of I=1/2 nuclear spins are placed periodically along a quantum spin chain (1-D…
Magnon-mediated NMR quantum gates in a 1-D antiferromagnet
Atsushi Goto, Tadashi Shimizu, Kenjiro Hashi
We propose a method of controlling a quantum logic gate in a solid-state NMR quantum computer. A switchable inter-qubit coupling can be generated by using the longitudinal componen…
Origin for the enhanced copper spin echo decay rate in the pseudogap regime of the multilayer high-T_c cuprates
Atsushi Goto, W. G. Clark, Patrik Vonlanthen +5
We report measurements of the anisotropy of the spin echo decay for the inner layer Cu site of the triple layer cuprate, Hg_0.8Re_0.2Ba_2Ca_2Cu_3O_8 (T_c=126 K) in the pseudogap T…
