Designing pretty good state transfer via isospectral reductions
M. Röntgen, N. E. Palaiodimopoulos, C. V. Morfonios +4
We present an algorithm to design networks that feature pretty good state transfer (PGST), which is of interest for high-fidelity transfer of information in quantum computing. Real…

Open and closed spin chains as multiprocessor wires: optimal engineering and reachability
N. E. Palaiodimopoulos, I. Brouzos, N. Georgoulea +2
We consider the perfect transfer of a state between arbitrary nodes of one-dimensional spin-1/2 chain with optimally engineered couplings. Motivated by the fact that such a system…
