Using tiny magnets for computation | Markus Becherer | TEDxTUMSalon

Did you know that we have over one billion electronic switches in our smartphones? They switch one billion times per second, causing the phone to heat up and lose battery life. To prevent this from happening, Markus uses magnets - not the magnets we all know from our fridges, but nanomagnets, only a couple of atoms thick. Markus and his group turn them into switches which can communicate with each other, allowing information flow and computation. And there might even be more tricks out there for them to learn that nobody has thought about yet!

CMOS logic has important properties when it comes to stability. Input a signal that's closer to 0.05 than to 0, and the inverter compensates by giving a precise output of 1. Because of this they tolerate noise and loss.
The magnetic circuits shown here don't appear to have any element which does this role. I would expect that for the majority circuit, if you feed it (1, 1, 0), you probably get an output closer to 0.05 instead of a precise logic 0, and then if you feed that into another circuit, it degrades further and eventually quits working as intended. How do these circuits deal with noise and loss?

who's here from datta's class lmao
