Nonequilibrium Monte Carlo for unfreezing variables in hard combinatorial optimization
Masoud Mohseni, Daniel Eppens, Johan Strumpfer +7
Optimizing highly complex cost/energy functions over discrete variables is at the heart of many open problems across different scientific disciplines and industries. A major obstac…
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…
Totally Corrective Boosting with Cardinality Penalization
Vasil S. Denchev, Nan Ding, Shin Matsushima +2
We propose a totally corrective boosting algorithm with explicit cardinality regularization. The resulting combinatorial optimization problems are not known to be efficiently solva…
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…
