Systematic Dimensionality Reduction for Quantum Walks: Optimal Spatial Search and Transport on Non-Regular Graphs
Leonardo Novo, Shantanav Chakraborty, Masoud Mohseni +2
Continuous time quantum walks provide an important framework for designing new algorithms and modelling quantum transport and state transfer problems. Often, the graph representing…
Computational Role of Collective Tunneling in a Quantum Annealer
Sergio Boixo, Vadim N. Smelyanskiy, Alireza Shabani +7
Quantum tunneling is a phenomenon in which a quantum state traverses energy barriers above the energy of the state itself. Tunneling has been hypothesized as an advantageous physic…
Construction of non-convex polynomial loss functions for training a binary classifier with quantum annealing
Ryan Babbush, Vasil Denchev, Nan Ding +2
Quantum annealing is a heuristic quantum algorithm which exploits quantum resources to minimize an objective function embedded as the energy levels of a programmable physical syste…
