Three level atom optics in dipole traps and waveguides
K. Eckert, J. Mompart, R. Corbalan +2
An analogy is explored between a setup of three atomic traps coupled via tunneling and an internal atomic three-level system interacting with two laser fields. Within this scenario…
Differential atom interferometry beyond the standard quantum limit
K. Eckert, P. Hyllus, D. Bruss +6
We analyze methods to go beyond the standard quantum limit for a class of atomic interferometers, where the quantity of interest is the difference of phase shifts obtained by two i…
Three level atom optics via the tunneling interaction
K. Eckert, M. Lewenstein, R. Corbalan +3
Three level atom optics (TLAO) is introduced as a simple, efficient and robust method to coherently manipulate and transport neutral atoms. The tunneling interaction among three tr…
Quantum computing with spatially delocalized qubits
J. Mompart, K. Eckert, W. Ertmer +2
We analyze the operation of quantum gates for neutral atoms with qubits that are delocalized in space, i.e., the computational basis states are defined by the presence of a neutral…
Quantum computing in optical microtraps based on the motional states of neutral atoms
K. Eckert, J. Mompart, X. X. Yi +4
We investigate quantum computation with neutral atoms in optical microtraps where the qubit is implemented in the motional states of the atoms, i.e., in the two lowest vibrational…
Detection of entanglement with few local measurements
O. Guehne, P. Hyllus, D. Bruss +4
We introduce a general method for the experimental detection of entanglement by performing only few local measurements, assuming some prior knowledge of the density matrix. The ide…
