Rydberg state engineering of trapped ions
Robin Thomm, Vinay Shankar, Natalia Kuk +3
Microwave dressing of Rydberg ions creates tunable eigenstates with controllable polarizability and interaction strength, but coherent navigation between these states has remained…
Probing electronic state-dependent conformational changes in a trapped Rydberg ion Wigner crystal
Marion Mallweger, Natalia Kuk, Vinay Shankar +6
State-dependent conformational changes play a central role in molecular dynamics, yet they are often difficult to observe or simulate due to their complexity and ultrafast nature.…
Experimental observation of anomalous supralinear response of single-photon detectors
Josef Hloušek, Ivo Straka, Miroslav Ježek
We demonstrate a direct single-source measurement of absolute nonlinearity of single-photon detectors with unprecedented accuracy. We discover a surprising supralinear behavior of…
Shaping the autocorrelation and photon statistics
Ivo Straka, Miroslav Ježek
We propose a method of arbitrarily shaping and scaling the temporal intensity correlations of an optical signal locally, avoiding periodic correlations. We demonstrate our approach…
Effect of source statistics on utilizing photon entanglement in quantum key distribution
Radim Hošák, Ivo Straka, Ana Predojević +2
A workflow for evaluation of entanglement source quality is proposed. Based on quantum state density matrices obtained from theoretical models and experimental data, we make an est…
Experimental quantum decoherence control by dark states of the environment
Robert Stárek, Michal Mičuda, Ivo Straka +5
Coherent interaction of a quantum system with environment usually induces quantum decoherence. However, remarkably, in certain configurations the coherent system-environment coupli…
