Exponential Enhancement of the Efficiency of Quantum Annealing by Non-Stochastic Hamiltonians
Hidetoshi Nishimori, Kabuki Takada
Non-stoquastic Hamiltonians have both positive and negative signs in off-diagonal elements in their matrix representation in the standard computational basis and thus cannot be sim…

Critical properties of dissipative quantum spin systems in finite dimensions
Kabuki Takada, Hidetoshi Nishimori
We study the critical properties of finite-dimensional dissipative quantum spin systems with uniform ferromagnetic interactions. Starting from the transverse-field Ising model coup…
