The positivity problem in quantum many-body systems is the difficulty of representing the positivity of the state with a tensor network.

The formalism of quantum physics is built upon that of classical mechanics. In principle, considering only experimental data without prior knowledge could lead to an alternative quantum formalism without conceptual issues like the measurement…

Profs. Roman Schmied and Nicolas Sangouard, co-authors of the winning publication, will collect the prize and give a talk about the awarded work. At the end, amid drinks and a small buffet, the audience will have the chance to interact with them.

Quantum entanglement suggests the existence of delicate non-local relationships that nevertheless cannot be used to transmit information.

Can physics tell us when democratic systems may be unstable

The workshop took place from Monday Dec. 10th to Wednesday Dec. 12th at IQOQI Vienna

Probability in quantum mechanics

Quantum Bayesianism (QBism) has attracted considerable attention in recent years, as a radically subjective interpretation of the quantum formalism.

Understanding linearized aspects of gravity in the framework of quantum mechanics is one of the great challenges in modern physics.

Supermaps are functions taking maps as input.
