Abstract:As ultracold atoms experiments move towards realistic quantum simulations of many-body physics problems, new techniques are being developed to increase the complexity of these systems. While the effects of real electric or magnetic fields...

Abstract: The capacity of the classical channel was investigated by Claude Shannon in 1948. This capacity is additive under the tensor products of two channels. The capacity of a quantum channel (QC) was introduced by Alexander Holevo in 1998. One of...

Abstract: The first experiment describes a precision test for Born rule for probabilities in quantum mechanics. The quadratic nature of the Born probability expression entails that interference occurs in pairs of paths. We tested the correctness of...

The main objective of PDMW is to bring together researchers in discrete mathematics in the prairie region (Manitoba, Saskatchewan and Alberta), as well as neighbouring provinces and states, with the goal of providing opportunities for networking and...

Abstract: The idea of weak measurement was introduced by Aharonov, Albert and Vaidman in 1988. It not only provides a theoretical framework for addressing counterintuitive quantum phenomena and fundamental questions, but also gives a practical tool...

In quantum information, entanglement has often been viewed as a resource. But in this talk, I will look at (pure bipartite) entanglement through the lens of superselection rules. The idea is that it requires quantum communication not only to create...

Quantum mechanics predicts the existence of correlations between two quantum systems which cannot be described merely by shared randomness. Such correlations, termed entanglement, have been analysed from a fundamental perspective since the beginning...

Abstract: The recent emergence of photon-number-resolving detectors (PNRDs) makes the characterization of multiphoton states via photoncounting possible. Here I will discuss several popular types of PNRDs and show how we can model realistic PNRDs...

Abstract: We propose a method which we call "Isotropic Entanglement" (IE), that predicts the eigenvalue distribution of quantum many body (spin) systems (QMBS) with generic interactions. We interpolate between two known approximations by matching...
