What to know about Randomization can improve quantum computer performance in presence of noise

Researchers from the University of New Mexico, led by Ph.D. student Leeseok Kim, have developed a randomized dynamical decoupling method to improve noise suppression in quantum computers. The findings, published in Physical Review Letters, suggest that this randomized approach can outperform deterministic protocols and be easily integrated into existing platforms.
