Bell's theorem is typically understood as the proof that quantum theory is incompatible with local-hidden-variable models.
Structured light is attracting significant attention for its diverse applications in both classical and quantum optics.
Phase estimation protocols provide a fundamental benchmark for the field of quantum metrology.
The difficulty of validating large-scale quantum devices, such as Boson Samplers, poses a major challenge for any research program that aims to show quantum advantages over classical hardware.
The number of parameters describing a quantum state is well known to grow exponentially with the number of particles.
A loophole-free violation of Bell inequalities is of fundamental importance for demonstrating quantum nonlocality and long-distance device-independent secure communication.
