Negative correlations can play a positive role in disordered quantum walks

Abstract We investigate the emerging properties of quantum walks with temporal disorder engineered from a binary Markov chain with tailored correlation, C, and disorder strength, r. We show that when the disorder is weak— $$r \ll 1$$ r ≪ 1 —the introduction of negative correlation leads to a counter...
