##### An invitation to quantum magic squares, by the Science Breaker

One can imagine a quantum magic square as coming from a very weird composition of quantum measurements. Start by noting that every row (or column) of a quantum magic square defines a POVM. The weird composition rule says that one can only compose POVMs which, when stuck on top of each other, define a quantum magic square. Is this physical, in any sense? In what world would a composition like that make sense? I don't know. What we find is that this composed object has some very different properties than the individual ones. For example, it cannot be dilated to a quantum permutation matrix (whereas every POVM can be dilated to a projective measurement). That's just one way of viewing quantum magic squares.

##### The mathematical magic hiding in the Sagrada Familia

I tried to share some of the magic of quantum theory, of magic squares and of quantum magic squares here. How beautiful is this sculpture, called The Lovers, at the Sagrada Familia? Not to speak of the Sagrada Familia itself... I should translate the article soon.

##### From simplicity to universality

TEDx Talk (June 2021) where I tried to explain the things that I'm trying to understand myself... PS: the talk was recorded on a stage without an audience so it made me feel like an actress :) If you watch the talk I'd be grateful if you shared your opinions / thoughts with me.
