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…
Learning parameter curves in feedback-based quantum optimization algorithms
Vicente Peña Pérez, Matthew D. Grace, Christian Arenz +1
Feedback-based quantum algorithms (FQAs) operate by iteratively growing a quantum circuit to optimize a given task. At each step, feedback from qubit measurements is used to inform…
Non-Variational ADAPT algorithm for quantum simulations
Ho Lun Tang, Yanzhu Chen, Prakriti Biswas +3
We explore a non-variational quantum state preparation approach combined with the ADAPT operator selection strategy in the application of preparing the ground state of a desired ta…
Tighter Lower Bounds on Quantum Annealing Times
Luis Pedro GarcÃa-Pintos, Mrunmay Sahasrabudhe, Christian Arenz
We derive lower bounds on the time needed for a quantum annealer to prepare the ground state of a target Hamiltonian. These bounds do not depend on the annealing schedule and can t…
