To demystify the notion that quantum computing owes its advantage to "massive parallelism" I find it useful to compare it to a random walk in a maze. A marble can explore many paths in the maze...

Last week @pintofscience.fr, the werewolves attacked some of our quantum channels but thankfully Alice and Bob were able to detect the intrusion.

The werewolves are on the prowl but the villagers are prepared!
Next week at @pintofscience.fr, werewolves will attack BB84 quantum channels #pint25

We had such a blast working with Le Cirque Graphique. Do you see what quantum gate they are illustrating here?

I strongly believe that mathematical notation, not mathematics, is the biggest obstacle when communicating about quantum computing. Two eye-opening reads.

Two qubits side by side, are correlated by a cog to illustrate entanglement.
If we stack the qubits, we can see that 2 qubits form a 4-dimensional system. It becomes easy to visualize partial traces and partial measurements.

A device to help visualize quantum entanglement. Each qubit is a 2-colored disc. We measure them by spinning around and stopping at a random spot. Whatever is visible in the measurement window is the outcome. We can see the correlation between the meausurement outcomes when the cog is in place.
