The More You Know: Quantum Simulator

A Quantum Simulator is a controllable quantum mechanical system than can be used to study more complex quantum system that cannot be directly studied nor simulated by any classical computer. One of the most important consequences of the existence of … Continue reading

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

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

This Blog’s Motivation: A Brief Introduction to Quantum Information and Quantum Computation

To me quantum computation is a new and deeper and better way to understand the laws of physics, and hence understanding physical reality as a whole. We are really only scratching the surface of what it is telling us about … Continue reading
