Local theories with parallel realities and the epistemic view of the quantum state
Alberto Montina, Stefan Wolf
Hidden-variable theories effectively solve the measurement problem. However, a serious issue of this route towards a realistic completion of quantum theory is raised by Bell's proo…

Temperature as Joules per Bit
Charles Alexandre Bédard, Sophie Berthelette, Xavier Coiteux-Roy +1
In statistical mechanics, entropy is defined as a fundamental quantity. However, its unit, J/K, involves that of temperature, which is only subsequently defined - and defined in te…

On multivariate polynomials achievable with quantum signal processing
Lorenzo Laneve, Stefan Wolf
Quantum signal processing (QSP) is a framework which was proven to unify and simplify a large number of known quantum algorithms, as well as discovering new ones. QSP allows one to…
