Tuning up Rydberg atoms for quantum information applications

11 mayo 2015

Rydberg atoms, atoms whose outermost electrons are highly excited but not ionized, might be just the thing for processing quantum information. These outsized atoms can be sustained for a long time in a quantum superposition condition — a good thing for creating qubits — and they can interact strongly with other such atoms, making them useful for devising the kind of logic gates needed to process information.
