Efficient multiparticle entanglement via asymmetric Rydberg blockade
M. Saffman, K. Molmer
We present an efficient method for producing particle entangled states using Rydberg blockade interactions. Optical excitation of Rydberg states that interact weakly, yet have…
Spin squeezing of atomic ensembles by multi-colour quantum non-demolition measurements
M. Saffman, D. Oblak, J. Appel +1
We analyze the creation of spin squeezed atomic ensembles by simultaneous dispersive interactions with several optical frequencies. A judicious choice of optical parameters enables…
Observation of Rydberg blockade between two atoms
E. Urban, T. A. Johnson, T. Henage +4
We demonstrate experimentally that a single Rb atom excited to the level blocks the subsequent excitation of a second atom located more than away. The obser…
Scaling the neutral atom Rydberg gate quantum computer by collective encoding in Holmium atoms
M. Saffman, K. Molmer
We discuss a method for scaling a neutral atom Rydberg gate quantum processor to a large number of qubits. Limits are derived showing that the number of qubits that can be directly…
Non-Destructive Probing of Rabi Oscillations on the Cesium Clock Transition near the Standard Quantum Limit
P. J. Windpassinger, D. Oblak, P. G. Petrov +7
We report on non-destructive observation of Rabi oscillations on the Cs clock transition. The internal atomic state evolution of a dipole-trapped ensemble of cold atoms is inferred…
