Tweezer-assisted subwavelength positioning of atomic arrays in an optical cavity
Matthias Seubert, Lukas Hartung, Stephan Welte +2
We present an experimental technique that enables the preparation of defect-free arrays of 87Rb atoms within a microscopic high-finesse optical standing-wave cavity. By employing o…
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…
Detecting an Itinerant Optical Photon Twice without Destroying It
Emanuele Distante, Severin Daiss, Stefan Langenfeld +5
Nondestructive quantum measurements are central for quantum physics applications ranging from quantum sensing to quantum computing and quantum communication. Employing the toolbox…
Quantum Teleportation between Remote Qubit Memories with Only a Single Photon as a Resource
Stefan Langenfeld, Stephan Welte, Lukas Hartung +5
Quantum teleportation enables the deterministic exchange of qubits via lossy channels. While it is commonly believed that unconditional teleportation requires a preshared entangled…
A Quantum-Logic Gate between Distant Quantum-Network Modules
Severin Daiss, Stefan Langenfeld, Stephan Welte +5
The big challenge in quantum computing is to realize scalable multi-qubit systems with cross-talk free addressability and efficient coupling of arbitrarily selected qubits. Quantum…
