Leveraging Landau-Zener-Stückelberg interference for accelerating diabatic quantum annealing
Matthias Werner, Matías Jonsson, Artur García-Sáez +2
Diabatic quantum annealing with variationally optimized schedules can exhibit exponential speedups over conventional adiabatic quantum annealing, as was demonstrated numerically fo…
Trajectory-independent speed limits for controlled open quantum systems
James B. Larsen, Tameem Albash, Alicia B. Magann +1
Existing quantum speed limits for controlled open quantum systems depend on the specified trajectory. For example, lower bounds on quantum annealing times in the presence of dissip…
Simulating the Open System Dynamics of Multiple Exchange-Only Qubits using Subspace Monte Carlo
Tameem Albash, N. Tobias Jacobson
We propose a Monte Carlo based method for simulating the open system dynamics of multiple exchange-only (EO) qubits. In the EO encoding, the total spin projection quantum number al…
