Qubit regularization of asymptotic freedom
Tanmoy Bhattacharya, Alexander J. Buser, Shailesh Chandrasekharan +2
We provide strong evidence that the asymptotically free (1+1)-dimensional non-linear O(3) sigma model can be regularized using a quantum lattice Hamiltonian, referred to as the "He…

State preparation and measurement in a quantum simulation of the O(3) sigma model
Alexander J. Buser, Tanmoy Bhattacharya, Lukasz Cincio +1
Recently, Singh and Chandrasekharan showed that fixed points of the non-linear O(3) sigma model can be reproduced near a quantum phase transition of a spin model with just two qubi…
