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…
Single-Photon Distillation via a Photonic Parity Measurement Using Cavity QED
Severin Daiss, Stephan Welte, Bastian Hacker +2
Single photons with tailored temporal profiles are a vital resource for future quantum networks. Here we distill them out of custom-shaped laser pulses that reflect from a single a…
Deterministic creation of entangled atom-light Schrödinger-cat states
Bastian Hacker, Stephan Welte, Severin Daiss +4
Quantum physics allows for entanglement between microscopic and macroscopic objects, described by discrete and continuous variables, respectively. As in Schrödinger's famous cat ge…
