Digital controllability of transverse field Ising chains
Vincenzo Roberto Arezzo, Ruiyi Wang, Kiran Thengil +2
Quantum Annealing (QA) encounters limitations when the energy gap along the annealing path becomes exponentially small, leading to impractically long runtimes. In contrast, the suc…

From Exponential to Quadratic: Optimal Control for a Frustrated Ising Ring Model
Ruiyi Wang, Vincenzo Roberto Arezzo, Kiran Thengil +2
Exponentially small spectral gaps are known to be the crucial bottleneck for traditional Quantum Annealing (QA) based on interpolating between two Hamiltonians, a simple driving te…
