A generalization of Schur-Weyl duality with applications in quantum estimation
Iman Marvian, Robert W. Spekkens
Schur-Weyl duality is a powerful tool in representation theory which has many applications to quantum information theory. We provide a generalization of this duality and demonstrat…
Reconstruction of Gaussian quantum mechanics from Liouville mechanics with an epistemic restriction
Stephen D. Bartlett, Terry Rudolph, Robert W. Spekkens
How would the world appear to us if its ontology was that of classical mechanics but every agent faced a restriction on how much they could come to know about the classical state?…
The Resource Theory of Quantum States Out of Thermal Equilibrium
Fernando G. S. L. Brandão, Michał Horodecki, Jonathan Oppenheim +2
The ideas of thermodynamics have proved fruitful in the setting of quantum information theory, in particular the notion that when the allowed transformations of a system are restri…
A Bayesian approach to compatibility, improvement, and pooling of quantum states
M. S. Leifer, R. W. Spekkens
In approaches to quantum theory in which the quantum state is regarded as a representation of knowledge, information, or belief, two agents can assign different states to the same…
Towards a Formulation of Quantum Theory as a Causally Neutral Theory of Bayesian Inference
M. S. Leifer, R. W. Spekkens
Quantum theory can be viewed as a generalization of classical probability theory, but the analogy as it has been developed so far is not complete. Whereas the manner in which infer…
The asymmetry properties of pure quantum states
Iman Marvian, Robert W. Spekkens
The asymmetry properties of a state relative to some symmetry group specify how and to what extent the given symmetry is broken by the state. Characterizing these is found to be su…
