Creating collective many-body states with highly excited atoms
B. Olmos, R. González-Férez, I. Lesanovsky
We study the collective excitation of a gas of highly excited atoms confined to a large spacing ring lattice, where the ground and the excited states are coupled resonantly via a l…
Fermionic collective excitations in a lattice gas of Rydberg atoms
B. Olmos, R. González-Férez, I. Lesanovsky
We investigate the many-body quantum states of a laser-driven gas of Rydberg atoms confined to a large spacing ring lattice. If the laser driving is much stronger than the van-der-…
Amplitude Noise Squeezing in Cavity-Driven Oscillations of a Mechanical Resonator
D. A. Rodrigues, A. D. Armour
We analyze the amplitude and phase noise of limit-cycle oscillations in a mechanical resonator coupled parametrically to an optical cavity driven above its resonant frequency. At a…
Passing quantum correlations to qubits using any two-mode state
Mauro Paternostro, Gerardo Adesso, Steve Campbell
We draw an explicit connection between the statistical properties of an entangled two-mode continuous variable (CV) resource and the amount of entanglement that can be dynamically…
A Rydberg Quantum Simulator
Hendrik Weimer, Markus Müller, Igor Lesanovsky +2
Following Feynman and as elaborated on by Lloyd, a universal quantum simulator (QS) is a controlled quantum device which reproduces the dynamics of any other many particle quantum…
Dynamics of Entanglement and `Attractor' states in The Tavis-Cummings Model
C. E. A. Jarvis, D. A. Rodrigues, B. L. Györffy +3
We study the time evolution of two-level atoms (or qubits) interacting with a single mode of the quantised radiation field. In the case of two qubits, we show that for a set…
