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…
A nondestructive Bell-state measurement on two distant atomic qubits
Stephan Welte, Philip Thomas, Lukas Hartung +5
One of the most fascinating aspects of quantum networks is their capability to distribute entanglement as a nonlocal communication resource. In a first step, this requires network-…
A quantum-network register assembled with optical tweezers in an optical cavity
Lukas Hartung, Matthias Seubert, Stephan Welte +2
Quantum computation and quantum communication are expected to provide users with capabilities inaccessible by classical physics. However, scalability to larger systems with many qu…
Fusion of deterministically generated photonic graph states
Philip Thomas, Leonardo Ruscio, Olivier Morin +1
Entanglement has evolved from an enigmatic concept of quantum physics to a key ingredient of quantum technology. It explains correlations between measurement outcomes that contradi…
Efficient generation of entangled multi-photon graph states from a single atom
Philip Thomas, Leonardo Ruscio, Olivier Morin +1
Entanglement is a powerful concept with an enormous potential for scientific and technological advances. A central focus in modern research is to extend the generation and control…
