Decoy-state quantum key distribution over 227 km with a frequency-converted telecom single-photon source
Frederik Brooke Barnes, Roberto G. Pousa, Christopher L. Morrison +7
We implement a decoy-state quantum key distribution scheme using a telecom C-band single-emitter source. The decoy states are created by varying the optical excitation of the quant…
Kinetically constrained cavity QED: from blockaded ferromagnetism to long-range quantum scars
Hossein Hosseinabadi, Riccardo J. Valencia-Tortora, Aleksandr N. Mikheev +4
Rydberg-cavity systems are emerging as promising platforms for quantum simulation and quantum information processing. These hybrid architectures combine two complementary interacti…
Non-stabilizerness in quantum-enhanced metrological protocols
Tanausú Hernández-Yanes, Piotr Sierant, Jakub Zakrzewski +1
Non-stabilizerness (colloquially "magic") characterizes genuinely quantum (beyond-Clifford) operations necessary for preparation of quantum states, and can be measured by stabilize…
Learning Minimal Representations of Many-Body Physics from Snapshots of a Quantum Simulator
Frederik Møller, Gabriel Fernández-Fernández, Thomas Schweigler +3
Analog quantum simulators provide access to many-body dynamics beyond the reach of classical computation. However, extracting physical insights from experimental data is often hind…
Quantum contextuality from measurement invasiveness
Andrea Navoni, Marco G. Genoni, Andrea Smirne
Contextuality is a defining feature that separates the quantum from the classical descriptions of physical systems. Within the marginal-scenario framework, noncontextual models are…
Quantum Kramers-Henneberger Transformation
Javier Argüello-Luengo, Javier Rivera-Dean, Philipp Stammer +2
The classical Kramers-Henneberger transformation connects, via a series of unitary transformations, the dynamics of a quantum particle of mass located in a trap at position $α(…
