Linear-time classical approximate optimization of cubic-lattice classical spin glasses
Adil A. Gangat
Demonstrating quantum speedup for approximate optimization of classical spin glasses is of current interest. Such a demonstration must be done with respect to the best-known scalin…

Hyperoptimized approximate contraction of tensor networks for rugged-energy-landscape spin glasses on periodic square and cubic lattices
Adil A. Gangat, Johnnie Gray
Obtaining the low-energy configurations of spin glasses that have rugged energy landscapes is of direct relevance to combinatorial optimization and fundamental science. Search-base…

Quantum clocks driven by measurement
A. A. Gangat, G. J. Milburn
In classical physics, clocks are open dissipative systems driven from thermal equilibrium and necessarily subject to thermal noise. We describe a quantum clock driven by entropy re…
