The More You Know: Bell States/EPR Pairs

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.

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.

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
