Searching for dark matter with a 1000 km baseline interferometer
Daniel Gavilan-Martin, Grzegorz Lukasiewicz, Mikhail Padniuk +8
Axion-like particles (ALPs) arise from well-motivated extensions to the Standard Model and could account for dark matter. ALP dark matter would manifest as a field oscillating at a…

Perfect quantum protractors
Michał Piotrak, Marek Kopciuch, Arash Dezhang Fard +3
In this paper we introduce and investigate the concept of a perfect quantum protractor, a pure quantum state that generates three different orthogonal bas…

Optimized experimental optical tomography of quantum states of room-temperature alkali-metal vapor
Marek Kopciuch, Magdalena Smolis, Adam Miranowicz +1
We demonstrate a novel experimental technique for quantum-state tomography of the collective density matrix. It is based on measurements of the polarization of light, traversing th…
