Exponential acceleration of macroscopic quantum tunneling in a Floquet Ising model
George Grattan, Brandon A. Barton, Sean Feeney +6
The exponential suppression of macroscopic quantum tunneling (MQT) in the number of elements to be reconfigured is an essential element of broken symmetry phases. This suppression…

Iterative quantum optimization of spin glass problems with rapidly oscillating transverse fields
Brandon Barton, Jacob Sagal, Sean Feeney +5
In this work, we introduce a new iterative quantum algorithm, called Iterative Symphonic Tunneling for Satisfiability problems (IST-SAT), which solves quantum spin glass optimizati…

On the approximability of random-hypergraph MAX-3-XORSAT problems with quantum algorithms
Eliot Kapit, Brandon A. Barton, Sean Feeney +5
A canonical feature of the constraint satisfaction problems in NP is approximation hardness, where in the worst case, finding sufficient-quality approximate solutions is exponentia…
