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…
Experimental demonstration of enhanced quantum tomography via quantum reservoir processing
Tanjung Krisnanda, Pengtao Song, Adrian Copetudo +4
Quantum machine learning is a rapidly advancing discipline that leverages the features of quantum mechanics to enhance the performance of computational tasks. Quantum reservoir pro…
Unmasking the Polygamous Nature of Quantum Nonlocality
PaweÅ CieÅliÅski, 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
PaweÅ CieÅliÅski, 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…
