Quantum Fidelity, or, how to compare quantum states
Say you are given two quantum states and , and you are asked the following questions: How similar are they? Can you distinguish them? In practice, this situation arises in many scenarios. For instance if you have an imperfect experiment … Continue reading
My new life as a Postdoc
Hello World! Whelp… it seems like my last post was published in March 4th 2018, which I now realize means that I haven’t been active for over a year (!). So, let me give you a brief summary of what … Continue reading
Quantum Computation with Light
Optical devices are among the most used and widespread technologies currently employed to perform quantum computations and quantum information processing tasks. They are usually cheaper than other implementations and are natural candidates for realizing communications protocols: Once a photonic state is … Continue reading
Our latest paper: “Factorization and criticality in finite interacting spin systems under a nonuniform magnetic field”
Our latest paper just got published by Physical Review Letter! Let me briefly explain what our manuscript is about: Factorization and criticality in finite interacting spin systems under a nonuniform magnetic field Exact ground states of strongly interacting spin … Continue reading

Why we should be talking about the ethics of quantum computation
Gyges was a shepherd in the service of the king of Lydia; there was a great storm, and an earthquake made an opening in the earth at the place where he was feeding his flock. Amazed at the sight, he … Continue reading
Tools for Drawing Quantum Circuits
Last night I was writing an article for the series “The more You Know” to add to my Dictionary of Quantum Information and Quantum Computation and I ran across the need to draw a Quantum Circuit. Although my first thought was … Continue reading
Announcement: Introducing Entangled Physics New Logo
I am very proud to present Entangled Physics new identity. This logo is composed by two entangled atoms bound by an infinite. It’s design is clean, modern and friendly, and the text “Entangled Physics” is written in an easily readable … 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
