Probing the Strong Equivalence Principle through the External Field Effect. How Do Two Masses Fall?

Ankit Kumar, Kelvin Tang Tee Tniam, Peng Chengxiaohe +5

Despite compelling evidence, the absence of a confirmed dark matter particle has sustained interest in modified gravity as an alternative explanation for the observed phenomenology…

Gravitational Entanglement in Optomechanics: Distinguishing Classical and Quantum Models

Samuel Schlegel, Ankit Kumar, Tomasz Paterek +1

Observation of gravitationally induced quantum entanglement is often interpreted as a direct evidence of non-classical gravity. While the form and the degree of non-classicality ha…

Unmasking the Polygamous Nature of Quantum Nonlocality

Paweł Cieśliński, Lukas Knips, Mateusz Kowalczyk +4

Quantum mechanics imposes limits on the statistics of certain observables. Perhaps the most famous example is the uncertainty principle. Similar trade-offs also exist for the simul…

Analysing quantum systems with randomised measurements

Paweł Cieśliński, Satoya Imai, Jan Dziewior +6

Measurements with randomly chosen settings determine many important properties of quantum states without the need for a shared reference frame or calibration. They naturally emerge…
