Phys.org  July 14, 2023 Quantum walks have been widely studied for their ability to simulate a wide range of transport phenomena. Physicists have previously studied two distinct types of quantum walk, but so far, they haven’t widely considered how their mathematical descriptions could be linked. They have long been considered the discrete-time and discrete space analogue of the Dirac equation and have been used as a primitive to simulate quantum field theories precisely because of some of their internal symmetries. Researchers in France have introduced a new family of quantum walks, a more general family named “twisted” quantum walkers, named […]
