Quantum jump simulation in three-level systems using photonic Gaussian modes
A. C. Cardoso, J. G. L. Condé, B. Marques +2
Multi-level quantum systems loose coherence due to quantum jumps or spontaneous decay between their internal levels. Here we propose a way to simulate experimentally a three-level…
Classical Imaging with Undetected Light
A. C. Cardoso, L. P. Berruezo, D. F. Ávila +5
We obtained the phase and intensity images of an object by detecting classical light which never interacted with it. With a double passage of a pump and a signal laser beams throug…
Popper's Experiment and the Uncertainty Principle
António Cardoso
In this paper we look at a particular realization of Popper's thought experiment with correlated quantum particles and argue that, from the point of view of a nonlinear quantum phy…
The quantum eraser does not always erase
António Cardoso, João L. Cordovil, José R. Croca
In this paper we will first look at a particular quantum eraser setup to show that this type of experiments can be understood in an intuitive manner if we are willing to take a com…
Interaction-Free Measurements: A Complex Nonlinear Explanation
António Cardoso, João L. Cordovil, José R. Croca
In this paper we show that interaction-free measurements, which have been object of much discussion in the last few decades, can be explained in a natural and intuitive way in the…
Singularities in loop quantum cosmology
Thomas Cailleteau, Antonio Cardoso, Kevin Vandersloot +1
We show that simple scalar field models can give rise to curvature singularities in the effective Friedmann dynamics of Loop Quantum Cosmology (LQC). We find singular solutions for…
