Quantum theory cannot consistently describe the use of itself
D Frauchiger, R Renner - Nature communications, 2018 - nature.com
Quantum theory provides an extremely accurate description of fundamental processes in
physics. It thus seems likely that the theory is applicable beyond the, mostly microscopic …

Enhanced communication with the assistance of indefinite causal order
D Ebler, S Salek, G Chiribella - Physical review letters, 2018 - APS
In quantum Shannon theory, the way information is encoded and decoded takes advantage
of the laws of quantum mechanics, while the way communication channels are interlinked is …

Indefinite causal order in a quantum switch
Quantum mechanics allows events to happen with no definite causal order: this can be
verified by measuring a causal witness, in the same way that an entanglement witness …

Quantum stochastic processes and quantum non-Markovian phenomena
The field of classical stochastic processes forms a major branch of mathematics. Stochastic
processes are, of course, also very well studied in biology, chemistry, ecology, geology …

Quantum mechanics and the covariance of physical laws in quantum reference frames
In physics, every observation is made with respect to a frame of reference. Although
reference frames are usually not considered as degrees of freedom, in all practical situations …

Charging quantum batteries via indefinite causal order: Theory and experiment
In the standard quantum theory, the causal order of occurrence between events is
prescribed, and must be definite. This has been maintained in all conventional scenarios of …

Quantum causal modelling
F Costa, S Shrapnel - New Journal of Physics, 2016 - iopscience.iop.org
Causal modelling provides a powerful set of tools for identifying causal structure from
observed correlations. It is well known that such techniques fail for quantum systems, unless …
