The More You Know: Bell States/EPR Pairs

Posted on 25 March, 2016 by marcocerezo

Bell States (named after John S. Bell) or EPR pairs (after Einsetin, Podolski and Rosen Paradox) are the maximally entangled quantum states of a two qubit system (i.e. a quantum mechanical system composed of two interacting two-level subsystems). In the computational basis the four … Continue reading →

Entanglement (II): Non-locality, Hidden Variables and Bell’s Inequalities.

Posted on 21 June, 2015 by marcocerezo

In the first article of this series, we studied Einstein, Podolski and Rosen’s paper, where we encountered for the first time the concept of quantum entangled stated and their “spooky action at a distance”. As EPR realized, when particles interact (under certain … Continue reading →

Entanglement (I): how it all began, the EPR Paradox.

Posted on 28 March, 2015 by marcocerezo

Being this the first article of this blog, I was torn as to where to begin. This is mainly because the fields of study of Quantum Information and Quantum Computation (QI and QC) are very wide and can be introduced in many ways. … Continue reading →
