Enhanced and reduced atom number fluctuations in a BEC splitter
Kenneth Maussang, G. Edward Marti, Tobias Schneider +6
We measure atom number statistics after splitting a gas of ultracold 87Rb atoms in a purely magnetic double-well potential created on an atom chip. Well below the critical temperat…
Atom chip based generation of entanglement for quantum metrology
Max F. Riedel, Pascal Böhi, Yun Li +3
Atom chips provide a versatile `quantum laboratory on a microchip' for experiments with ultracold atomic gases. They have been used in experiments on diverse topics such as low-dim…
Optimum spin-squeezing in Bose-Einstein condensates with particle losses
Yun Li, Yvan Castin, Alice Sinatra
The problem of spin squeezing with a bimodal condensate in presence of particle losses is solved analytically by the Monte Carlo wavefunction method. We find the largest obtainable…
Three-Way Entanglement and Three-Qubit Phase Gate Based on a Coherent Six-Level Atomic System
Chao Hang, Yun Li, Lei Ma +1
We analyze the nonlinear optical response of a six-level atomic system under a configuration of electromagnetically induced transparency. The giant fifth-order nonlinearity generat…
Controllable Entanglement of Lights in a Five-Level System
Yun Li, Chao Hang, Lei Ma +1
We analyze the nonlinear optical response of a five-level system under a novel configuration of electro-magnetically induced transparency. We show that a giant Kerr nonlinearity wi…
