Energy landscape transformation of Ising problem with invariant eigenvalues for quantum annealing
Toru Fujii, Koshi Komuro, Yosuke Okudaira +2
Quantum annealing tends to be more difficult as the energy landscape of the problem becomes complicated with many local minima. We have found a transformation for changing the ener…

Quantum Brachistochrone
Alberto Carlini, Akio Hosoya, Tatsuhiko Koike +1
We present a general framework for finding the time-optimal evolution and the optimal Hamiltonian for a quantum system with a given set of initial and final states. Our formulation…
