Donuts,math,and superdense teleportation of quantum information
Donuts math superdense teleportation quantum information
2015/6/18
Putting a hole in the center of the donut—a mid-nineteenth-century invention—allows the deep-fried pastry to cook evenly, inside and out. As it turns out, the hole in the center of the donut also hold...
Quantum information transfer with nitrogen-vacancy centers coupled to a whispering-gallery microresonator
Quantum information transfer nitrogen-vacancy centers coupled whispering-gallery microresonator
