In this review we present the potentialities and the achievements of the use of non-classical
photon-number correlations in twin-beam states for many applications, ranging from imaging …

In this review we present the problem of time in quantum physics, including a short history of
the problem and the known objections about considering time as a quantum observable …

Providing for a comprehensive model of physics that describes both the discrete and non-
discrete behavior of matter has proved difficult and elusive. Using a new approach, we …

The problem of time in quantum gravity calls for a relational solution. Using quantum
reduction maps, we establish a previously unknown equivalence between three approaches …

We give a consistent quantum description of time, based on Page and Wootters's conditional
probabilities mechanism, which overcomes the criticisms that were raised against similar …

What does it mean for one quantum process to be more disordered than another?
Interestingly, this apparently abstract question arises naturally in a wide range of areas such …

This article generalizes the conditional probability interpretation of time in which time
evolution is realized through entanglement between a clock and a system of interest. This …

We propose a time-of-arrival operator in quantum mechanics by conditioning on a quantum
clock. This allows us to bypass some of the problems of previous proposals, and to obtain a …

In a quantum world, reference frames are ultimately quantum systems too–but what does it
mean to" jump into the perspective of a quantum particle"? In this work, we show that …

In this chapter, we postulate an integral concept of information processing in the universe,
on the basis of a new biophysical principle, coined the generalized music (GM)-scale of EMF …
