Experimental realization of a momentum-space quantum walk
Siamak Dadras, Alexander Gresch, Caspar Groiseau +2
We report on a discrete-time quantum walk that uses the momentum of ultra-cold rubidium-87 atoms as the walk space and two internal atomic states as the coin degree of freedom. Eac…

Quantum Walks of kicked Bose-Einstein condensates
Caspar Groiseau, Alexander Gresch, Sandro Wimberger
We analytically investigate the recently proposed and implemented discrete-time quantum walk based on kicked ultra-cold atoms. We show how the internal level structure of the kicke…

Quantum Walk in Momentum Space with a Bose-Einstein Condensate
Siamak Dadras, Alexander Gresch, Caspar Groiseau +2
We present a discrete-time, one-dimensional quantum walk based on the entanglement between the momentum of ultracold rubidium atoms (the walk space) and two internal atomic states…
