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

The More You Know: EPR Paradox
The EPR Paradox is a thought experiment published in a paper in May 1935 by Albert Einstein and two of his postdoctoral research associates Boris Podolsky and Nathan Rosen that was meant to prove that Quantum Mechanics showed internal contradictions in it’s … Continue reading

Entangled particles, faster than light communications and the no-cloning theorem
In 1982, a paper entitled “FLASH – A Superluminal Communicator Based Upon a New Kind of Quantum Measurement” was published by Nick Herbert, an American physicist who meant to prove that by using EPR entangled pairs and quantum effects, a … 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
EPR’s Paradox Exemplified: Bohm’s Spin Experiment
After my post on Einstein, Podolski and Rosen’s paradox, a few of you guys asked me about how is it possible for both the position and momentum of a particle to be elements of reality at the same time. In particular, … Continue reading
Today’s Quote: How the term “Entanglement” came to be.
“When two systems, of which we know the states by their respective representatives, enter into temporary physical interaction due to known forces between them, and when after a time of mutual influence the systems separate again, then they can no longer be described … 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
