Bell-inequality violation in light transmitted through disordered emitter ensembles

Ruolin Guan, Vineesha Srivastava, Kasper J. Kusmierek +2

We show that light transmitted through a disordered ensemble of weakly coupled two-level emitters can violate a Bell inequality in a continuous-wave Franson-type measurement. The B…

Continuous Narrow-Linewidth Superradiance in Waveguide QED

Anna Bychek, Martin Fasser, Ivan Vybornyi +4

Superradiant lasers promise continuous, narrow-linewidth coherent emission at the bare atomic transition frequency, enabling frequency references of exceptional precision. Recent e…

Collective enhancement in sideband cooling of ion crystals

Ivan Vybornyi, Artem Zhdanov, Matthias Bock +4

Low-entropy motional states of ion Coulomb crystals are an essential prerequisite for a plethora of applications and are typically prepared by laser cooling. As larger crystals are…

Line search by quantum logic spectroscopy enhanced with squeezing and statistical tests

Ivan Vybornyi, Shuying Chen, Lukas J. Spieß +2

In quantum logic spectroscopy, internal transitions of trapped ions and molecules can be probed by measuring the motional displacement caused by an applied light field of variable…

Identification of highly-forbidden optical transitions in highly charged ions

Shuying Chen, Lukas J. Spieß, Alexander Wilzewski +6

Optical clocks represent the most precise experimental devices, finding application in fields spanning from frequency metrology to fundamental physics. Recently, the first highly c…

Sideband thermometry of ion crystals

Ivan Vybornyi, Laura S. Dreissen, Dominik Kiesenhofer +7

Coulomb crystals of cold trapped ions are a leading platform for the realisation of quantum processors and quantum simulations and, in quantum metrology, for the construction of op…

Backflash Light as a Security Vulnerability in Quantum Key Distribution Systems

Ivan Vybornyi, Abderrahmen Trichili, Mohamed-Slim Alouini

Based on the fundamental rules of quantum mechanics, two communicating parties can generate and share a secret random key that can be used to encrypt and decrypt messages sent over…
