Quantum theory at the macroscopic scale
Miguel Gallego, Borivoje DakiÄ
The quantum description of the microscopic world is incompatible with the classical description of the macroscopic world, both mathematically and conceptually. Nevertheless, it is…
Experimental Quantum State Certification by Actively Sampling Photonic Entangled States
Michael Antesberger, Mariana M. E. Schmid, Huan Cao +3
Entangled quantum states are essential ingredients for many quantum technologies, but they must be validated before they are used. As a full characterization is prohibitively resou…
Optimising quantum tomography via shadow inversion
Andrea Caprotti, Joshua Morris, Borivoje DakiÄ
In quantum information theory, the accurate estimation of observables is pivotal for quantum information processing, playing a crucial role in compute and communication protocols.…
Quantum coherence in networks
Fatemeh Bibak, Flavio Del Santo, Borivoje DakiÄ
From a quantum information perspective, verifying quantum coherence in a quantum experiment typically requires adjusting measurement settings or changing inputs. A paradigmatic exa…
Direct and Efficient Detection of Quantum Superposition
Daniel Kun, Teodor Strömberg, Michele Spagnolo +3
One of the most striking quantum phenomena is superposition, where one particle simultaneously inhabits different states. Most methods to verify coherent superposition are indirect…
