Spectrally enhanced gravitational redshift signals in photonic interferometry
Jerzy Paczos, Piotr T. Grochowski, Natalia Bruno +3
Quantum mechanics and general relativity are remarkably successful, yet their joint predictions remain beyond direct experimental reach. Photonic interferometers operating in a gra…
Metropolitan entanglement distribution between an atom and a near-visible photon
Maya Büki, Pooja Malik, Florian Fertig +9
Entanglement distribution is the overarching purpose of quantum networks. While communication over long distances can use deployed fiber infrastructure, it requires photons in the…
Collective vacuum-Rabi splitting with an atomic spin wave coupled to a cavity mode
Félix Hoffet, Alexey Vylegzhanin, Emanuele Distante +3
A promising platform for quantum information research relies on cavity coupled atomic spin-waves, enabling efficient operations such as quantum memories, quantum light generation a…
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…
Transient dynamics of the quantum light retrieved from Rydberg polaritons
Auxiliadora Padrón-Brito, Roberto Tricarico, Pau Farrera +4
We study the photon statistics of weak coherent pulses propagating through a cold Rydberg atomic ensemble in the regime of Rydberg electromagnetically induced transparency. We show…
Time Entanglement between a Photon and a Spin Wave in a Multimode Solid-state Quantum Memory
Kutlu Kutluer, Emanuele Distante, Bernardo Casabone +3
The generation and distribution of entanglement are key resources in quantum repeater schemes. Temporally multiplexed systems offer time-bin encoding of quantum information which p…
Storing single photons emitted by a quantum memory on a highly excited Rydberg state
Emanuele Distante, Pau Farrera, Auxiliadora Padrón-Brito +3
Strong interaction between two single photons is a long standing and important goal in quantum photonics. This would enable a new regime of nonlinear optics and unlock several appl…
Storage enhanced nonlinearities in a cold atomic Rydberg ensemble
Emanuele Distante, Auxiliadora Padrón-Brito, Matteo Cristiani +2
The combination of electromagnetically induced transparency (EIT) with the nonlinear interaction between Rydberg atoms provides an effective interaction between photons. In this pa…
