Enhancement of Rydberg-mediated single-photon nonlinearities by electrically tuned Förster Resonances
H. Gorniaczyk, C. Tresp, P. Bienias +6
Mapping the strong interaction between Rydberg atoms onto single photons via electromagnetically induced transparency enables manipulation of light on the single photon level and n…
Thermodynamics of quantum feedback cooling
Pietro Liuzzo-Scorpo, Luis A. Correa, Rebecca Schmidt +1
The ability to initialize quantum registers in pure states lies at the core of many applications of quantum technologies, from sensing to quantum information processing and computa…
Quantum communications and quantum metrology in the spacetime of a rotating planet
Jan Kohlrus, David Edward Bruschi, Jorma Louko +1
We study how quantum systems that propagate in the spacetime of a rotating planet are affected by the curved background. Spacetime curvature affects wavepackets of photons propagat…
Ultimate precision: Gaussian parameter estimation in flat and curved spacetime
Dominik Šafránek, Jan Kohlrus, David Edward Bruschi +2
Relativistic quantum metrology provides an optimal strategy for the estimation of parameters encoded in quantum fields in flat and curved spacetime. These parameters usually corres…
Observation of time-invariant coherence in a room temperature quantum simulator
Isabela A. Silva, Alexandre M. Souza, Thomas R. Bromley +9
The ability to live in coherent superpositions is a signature trait of quantum systems and constitutes an irreplaceable resource for quantum-enhanced technologies. However, decoher…
Statistically efficient tomography of low rank states with incomplete measurements
Anirudh Acharya, Theodore Kypraios, Madalin Guta
The construction of physically relevant low dimensional state models, and the design of appropriate measurements are key issues in tackling quantum state tomography for large dimen…
