Spontaneous emission of a photon: wave packet structures and atom-photon entanglement
M. V. Fedorov, M. A. Efremov, A. E. Kazakov +3
Spontaneous emission of a photon by an atom is described theoretically in three dimensions with the initial wave function of a finite-mass atom taken in the form of a finite-size w…
Observable Phase Entanglement
K. W. Chan, J. H. Eberly
Quantum entanglement can manifest itself in the narrowing of wavepackets. We define the phenomenon of phase entanglement and describe its effect on the interpretation of spatial lo…
Finite-Time Disentanglement via Spontaneous Emission
Ting Yu, J. H. Eberly
We show that under the influence of pure vacuum noise two entangled qubits become completely disentangled in a finite time, and in a specific example we find the time to be given b…
Packet narrowing and quantum entanglement in photoionization and photodissociation
M. V. Fedorov, M. A. Efremov, A. E. Kazakov +3
The narrowing of electron and ion wave packets in the process of photoionization is investigated, with the electron-ion recoil fully taken into account. Packet localization of this…
