Imposing Constraints on Driver Hamiltonians and Mixing Operators: From Theory to Practical Implementation
Hannes Leipold, Federico M. Spedalieri, Stuart Hadfield +1
Driver Hamiltonians and Mixing Operators that satisfy constraints is an important part of ansatz construction for many quantum algorithms. In this manuscript, we give general algeb…
Quantum Annealing with Special Drivers for Circuit Fault Diagnostics
Hannes Leipold, Federico M. Spedalieri
We present a very general construction for quantum annealing protocols to solve Combinational Circuit Fault Diagnosis (CCFD) problems that restricts the evolution to the space of v…
Constructing Driver Hamiltonians for Optimization Problems with Linear Constraints
Hannes Leipold, Federico M. Spedalieri
Recent advances in the field of adiabatic quantum computing and the closely related field of quantum annealers has centered around using more advanced and novel Hamiltonian represe…
Quantum Annealing for Constrained Optimization
Itay Hen, Federico M. Spedalieri
Recent advances in quantum technology have led to the development and manufacturing of experimental programmable quantum annealers that promise to solve certain combinatorial optim…
Reexamination of the evidence for entanglement in the D-Wave processor
Tameem Albash, Itay Hen, Federico M. Spedalieri +1
A recent experiment [Lanting et al., PRX, (2014)] claimed to provide evidence of up to -qubit entanglement in a D-Wave quantum annealing device. However, entanglement was measur…
Entanglement in a quantum annealing processor
T. Lanting, A. J. Przybysz, A. Yu. Smirnov +23
Entanglement lies at the core of quantum algorithms designed to solve problems that are intractable by classical approaches. One such algorithm, quantum annealing (QA), provides a…
