Efficient population transfer via non-ergodic extended states in quantum spin glass
Kostyantyn Kechedzhi, Vadim Smelyanskiy, Jarrod R. McClean +6
We analyze a new computational role of coherent multi-qubit quantum tunneling that gives rise to bands of non-ergodic extended (NEE) quantum states each formed by a superposition o…
What is the Computational Value of Finite Range Tunneling?
Vasil S. Denchev, Sergio Boixo, Sergei V. Isakov +5
Quantum annealing (QA) has been proposed as a quantum enhanced optimization heuristic exploiting tunneling. Here, we demonstrate how finite range tunneling can provide considerable…
Computational Role of Multiqubit Tunneling in a Quantum Annealer
Sergio Boixo, Vadim N. Smelyanskiy, Alireza Shabani +7
Quantum tunneling, a phenomenon in which a quantum state traverses energy barriers above the energy of the state itself, has been hypothesized as an advantageous physical resource…
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…
Robust Classification with Adiabatic Quantum Optimization
Vasil S. Denchev, Nan Ding, S. V. N. Vishwanathan +1
We propose a non-convex training objective for robust binary classification of data sets in which label noise is present. The design is guided by the intention of solving the resul…
Training a Large Scale Classifier with the Quantum Adiabatic Algorithm
Hartmut Neven, Vasil S. Denchev, Geordie Rose +1
In a previous publication we proposed discrete global optimization as a method to train a strong binary classifier constructed as a thresholded sum over weak classifiers. Our motiv…
