Emulating XX catalysts for quantum annealing via self-consistent transverse fields
Mohammadhossein Dadgar, Christopher L. Baldwin
The paper proposes a method to emulate fully‑connected transverse interaction catalysts for quantum annealing using a self‑consistent transverse field that only requires measuremen…
Reaching states below the threshold energy in spin glasses via quantum annealing
Christopher L. Baldwin
Although quantum annealing is usually considered as a method for locating the ground states of difficult spin-glass and optimization problems, its use in approximate optimization -…
Adiabatic reverse annealing is robust to low-temperature decoherence
An Le, Christopher L. Baldwin
Adiabatic reverse annealing (ARA) is an improvement to conventional quantum annealing (QA) that uses an initial guess at the desired ground state to circumvent problematic phase tr…
Simulated outperforms quantum reverse annealing in mean-field models
Christopher L. Baldwin
Adiabatic reverse annealing (ARA) has been proposed as an improvement to conventional quantum annealing for solving optimization problems, in which one takes advantage of an initia…
Sub-ballistic operator growth in spin chains with heavy-tailed random fields
Christopher L. Baldwin
We rigorously prove that in nearly arbitrary quantum spin chains with power-law-distributed random fields, namely such that the probability of a field exceeding scales as $h^{-…
The anomalously slow dynamics of inhomogeneous quantum annealing
Mohammadhossein Dadgar, Christopher L. Baldwin
Inhomogeneous quantum annealing (IQA), in which transverse fields are turned off one by one rather than simultaneously, has been proposed as an effective way to avoid the first-ord…
