- American Physical Society has started an open access journal, Physical Review X (X doesn’t stand for eXtreme).
- The open-access journal, New Journal of Physics has learned from the open science Quantiki’s video abstract format for the arXiv [Previously: my video abstract], and have announced video abstracts for their journal.
It is good to see some of the biggest names in physics journals embrace ideas pioneered by the open sciences community.
I hope they push further! Any comments of future directions you would like them to take?

Have you ever wondered how is science done? Why do people do it? What is the output? What is success, what is failure? Check out this wonderful one hour long documentary, Naturally Obsessed.
It follows a group of graduate students in a molecular biology laboratory. Independent of the details of their science, the focus is on where the people (grad students) doing it: their backgrounds, their personal lives, and their emotions in the laboratory. This is a vivid and clear exposition of the human aspect of doing science, without Hollywood drama, without heroic altruism. Science is enough drama on its own. Highly recommended.
Lisa: You should really listen to him. He’s a man of science, and you can barely read.
Homer: Bah, science. Has science ever kissed a woman, or won the Super Bowl, or put a man on the moon? Here’s what I think of your precious science. (Goes full speed into a blood vein. Submarine begins to go out of control) Help me science!
The game differs from classical Minesweeper in the following ways:
- The board is really a quantum superposition of two boards. It is your goal to figure out the superpositions. It is simplified, as only one kind of phase is allowed.
- There are three different kind of measurements that you can do, each one a limited number of times. The measurements are:
- classical measurement – collapse that can trigger a mine probabilistically. Very risky!
- entropy measurement – it indicates if there is a superposition or not, but doesn’t tell you if there is a mine or not!
- interaction-free measurements – it is very magical, doesn’t collapse the wave function, actually gives you the phase information. Very powerful!
This game is fantastic!
I have a question that might be a good undergraduate research project for someone interested in quantum information. What is the optimal strategy for the game? That is, if you thought of this game as a kind of state tomography problem, is there a general protocol to extract the state with high fidelity, given the constrains of the number of measurements? To make it more interesting, imagine a version of quantum minesweeper where the boards could have between them any kind of phase, how much harder would solving it be?
Give it one last try
til the next

This is a good introduction to my research. If you are curious about what I do, by all means watch it.

An infuriatingly theologically focused video interview can be found here. I’ll assume The Guardian editing is to blame.
Although I am always highly critical of all popularizations of quantum mechanics, I’ll admit I’m biased towards liking this one. Vlatko’s work on the thermodynamics of quantum information have influenced my own interests, and I’m currently working with several people in his group. I can’t wait for this book to come out.
