Harrigan and Spekkens (HS, 2007) provide a precise account of what it means to give an ontological model of an operational theory. In their framework, an ontological model specifies the possible ontic states of a system, where the ontic state is…

I argue that there is a common theme in the later Ludwig Wittgenstein, in Philip Frank and Otto Neurath:

Part II: Optimal LOCC implementations of Gaussian quantum channels for quantum gravity

While the spontaneous emission from independent emitters provides spatially uncorrelated photons—a typical manifestation of quantum randomness, the interference of the coherent scattering leads to a well-defined intensity pattern—a feature described…

The state of a quantum system can be represented by listing the outcome probabilities for a tomographically complete set of measurements.

The famous “It from Bit” slogan expresses a foundational research approach that emphasizes that all of our perceptions and concepts of the physical world are ultimately given in the form of data.

Bekenstein’s (1972, 1973) appeal to information-theoretic ideas in arguing that black hole entropy is genuine thermodynamic entropy has been widely debated.

Seventy years ago, John Wheeler’s student Hugh Everett wrote a dissertation proposing his theory of the universal wave function, a novel interpretation of quantum mechanics that would eventually evolve into today’s many worlds interpretation.

In 2019, the International System of Units (SI) was redefined. For many, this went by without a hitch -- and that's how it should be.

On this year’s World Quantum Day, IQOQI Vienna once again opens its doors to the public.
