Демон Максвелла, не к ночи будь помянут, у нас на семинаре

 Abstract of a talk: "I will describe the control that we have developed over the internal and motional states, as well as the positions of Cesium atoms trapped in a 3D optical lattice. We can execute arbitrary, site-selective single qubit gates with high fidelity (0.996) and low crosstalk (0.002). Initially, only a random half of the lattice sites are occupied with a single atom due to pairwise light assisted collisions. We cool them to the 3D vibrational ground state of the trap and move single atoms to generate fully filled sub-lattices, significantly lowering the entropy and creating a desirable starting point for a quantum computation. This “sorting” process is also an implementation of a Maxwell’s demon. I will also outline the path to implementing high fidelity entangling gates in this system and realize a 50 qubit quantum computer in the near future."

Жаль, я сейчас в Европе.

Omg. So, quantum computing to perpetuum mobile. Fine. Decrease the entropy worldwide.
