Quantum state identification of qutrits via a nonlinear protocol
P. V. Pyshkin, A. Gábris, O. Kálmán +2
We propose a probabilistic quantum protocol to realize a nonlinear transformation of qutrit states, which by iterative applications on ensembles can be used to distinguish two type…

High-fidelity non-adiabatic cutting and stitching of a spin chain via local control
P. V. Pyshkin, E. Ya. Sherman, J. Q. You +1
We propose and analyze, focusing on non-adiabatic effects, a technique of manipulating quantum spin systems based on local 'cutting' and 'stitching' of the Heisenberg exchange coup…
