Optimizing decoherence in the generation of optical Schrödinger cat states
Hendrik Hegels, Thomas Stolz, Gerhard Rempe +1
We propose to use cavity Rydberg electromagnetically induced transparency to generate Schrödinger cat states of optical photons. We predict that this should make it possible to ge…
Bright and Dark States of Light: The quantum Origin of Classical Interference
Celso J. Villas-Boas, Carlos E. Máximo, Paulo J. Paulino +2
Classical theory asserts that several electromagnetic waves cannot interact with matter if they interfere destructively to zero, whereas quantum mechanics predicts a nontrivial lig…
Removal of high-voltage-induced surface charges by ultraviolet light
M. T. Ziemba, J. Phrompao, F. Jung +2
A plethora of studies ranging from precision physics to quantum information employ ions, highly excited neutral atoms or polar molecules as tools. Motivated by the need for miniatu…
Coherence of Symmetry-Protected Rotational Qubits in Cold Polyatomic Molecules
Maximilian Löw, Martin Ibrügger, Gerhard Rempe +1
Polar polyatomic molecules provide an ideal but largely unexplored platform to encode qubits in rotational states. Here, we trap cold (100-600 mK) formaldehyde (HCO) inside an…
