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
Steven Weinberg on density matrix formalism
Just a friendly reminder as to why the density matrix formalism is so important and why it should be thought along side the state vector formalism. Nothing that is done in one system can instantaneously affect the density matrix of … Continue reading
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
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
The More You Know: Quantum Circuit
Quantum Circuits are used to visualize a prescription of quantum gates acting on a quantum state. They describe the changes of the quantum data as it undergoes successive discrete operations. The data in a Quantum Circuit is usually encoded in a qubit state (other Quantum Circuit … Continue reading
