Reducibility of native weighted graphs on Rydberg Arrays
J. Kombe, J. D. Pritchard
We investigate the classical reducibility of random unit-disk graph (UDG) instances of the maximum independent set (MIS) and maximum weighted independent set (MWIS) problems, which…
Adiabatic state preparation and thermalization of simulated phase noise in a Rydberg spin Hamiltonian
Tomas Kozlej, Gerard Pelegri, Jonathan D. Pritchard +1
Laser phase noise is one of the main sources of decoherence in driven Rydberg systems with neutral atoms in tweezer arrays. While the effect of phase noise in the regimes of isolat…
