We introduce the framework of general probabilistic theories (GPTs for short). GPTs are a
class of operational theories that generalize both finite-dimensional classical and quantum …

We establish an operational characterization of general convex resource theories—
describing the resource content of not only states but also measurements and channels …

Recently, table-top experiments involving massive quantum systems have been proposed to
test the interface of quantum theory and gravity. In particular, the crucial point of the debate …

The formalism of generalized probabilistic theories (GPTs) was originally developed as a
way to characterize the landscape of conceivable physical theories. Thus, the GPT …

Resource theories provide a general framework for the characterization of properties of
physical systems in quantum mechanics and beyond. Here we introduce methods for the …

We study a variant of quantum hypothesis testing wherein an additional 'inconclusive'
measurement outcome is added, allowing one to abstain from attempting to discriminate the …

We investigate practical dense coding by imposing locality restrictions on decoders and
symmetry restrictions on encoders within the resource theory of asymmetry framework. In …

Recently, Schmid and Spekkens studied the quantum contextuality in terms of state
discrimination. By dealing with the minimum error discrimination of two quantum states with …

Bit commitment is a fundamental cryptographic task, in which Alice commits a bit to Bob such
that she cannot later change the value of the bit, while, simultaneously, the bit is hidden from …

Symmetry shares an entwined history with the structure of physical theory. We propose a
consequence of symmetry towards the axiomatic derivation of Hilbert space quantum theory …
