Direct Equivalence between Dynamics of Quantum Walks and Coupled Classical Oscillators
Lilith Zschetzsche, Refik Mansuroglu, András Molnár +1
Continuous time quantum walks on exponentially large, sparse graphs form a powerful paradigm for quantum computing: On the one hand, they can be efficiently simulated on a quantum…
