Adiabatic theorem revisited: the unexpectedly good performance of adiabatic passage
Albert Benseny, Klaus Mølmer
Adiabatic passage employs a slowly varying time-dependent Hamiltonian to control the evolution of a quantum system along the Hamiltonian eigenstates. For processes of finite durati…
Retrodiction beyond the Heisenberg uncertainty relation
Han Bao, Shenchao Jin, Junlei Duan +4
In quantum mechanics, the Heisenberg uncertainty relation presents an ultimate limit to the precision by which one can predict the outcome of position and momentum measurements on…
Radiation Eigenmodes of Dicke Superradiance
Benjamin Lemberger, Klaus Mølmer
We calculate the field eigenmodes of the superradiant emission from an ensemble of two-level atoms. While numerical techniques are effective due to the symmetry of the problem,…
Collective emission of photons from dense, dipole-dipole interacting atomic ensembles
David Petrosyan, Klaus Mølmer
We study the collective radiation properties of cold, trapped ensembles of atoms. We consider the high density regime with the mean interatomic distance being comparable to, or sma…
Time-dependent atomic magnetometry with a recurrent neural network
Maryam Khanahmadi, Klaus Mølmer
We propose to employ a recurrent neural network to estimate a fluctuating magnetic field from continuous optical Faraday rotation measurement on an atomic ensemble. We show that an…
Ancilla mediated qubit readout and heralded entanglement between rare-earth dopant ions in crystals
Kamanasish Debnath, Alexander Holm Kiilerich, Klaus Mølmer
Owing to their long excited state lifetimes, rare-earth ions in crystals are widely used in quantum applications. To allow optical readout of the qubit state of individual ions, we…
