Light-shift induced behaviors observed in momentum-space quantum walks
Nikolai Bolik, Caspar Groiseau, Jerry H. Clark +5
Over the last decade there have been many advances in studies of quantum walks (QWs) including a momentum-space QW recently realized in our spinor Bose-Einstein condensate system.…
Quantum to Classical Walk Transitions Tuned by Spontaneous Emissions
J. H. Clark, C. Groiseau, Z. N. Shaw +5
We have realized a quantum walk in momentum space with a rubidium spinor Bose-Einstein condensate by applying a periodic kicking potential as a walk operator and a resonant microwa…
Quantum search with a continuous-time quantum walk in momentum space
Michele Delvecchio, Caspar Groiseau, Francesco Petiziol +2
The atom-optics kicked rotor can be used to prepare specific momentum distributions on a discrete basis set. We implement a continuous-time quantum walk and a quantum search protoc…
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 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…
Hamiltonian ratchets with ultra-cold atoms
Jiating Ni, Siamak Dadras, Wa Kun Lam +4
Quantum-resonance ratchets have been realized over the last ten years for the production of directed currents of atoms. These non-dissipative systems are based on the interaction o…
