There were quantum channels. And now superchannels!
The 3rd Krakow-Torun-Oslo workshop, “Beyond Quantum” (November 26–December 1), has now concluded. It was an intense brainstorming week (as always) where the main topic—What’s next?—was discussed. Holmenkollen and the weather provided the perfect conditions for day-long sessions, interspersed with coffee sips and lunch breaks.
The main topic this year was superchannels, quantum operations that map quantum channels onto quantum channels (where quantum channels, in turn, map quantum states onto quantum states). Perhaps the topic for next year’s workshop will be super-superchannels (metachannels?).
