The era of quantum computers is one step closer as a result of research published in the current issue of the journal Science. The research team has devised and demonstrated a modern way to pack a lot more quantum computing power into a much smaller space and with much greater control than ever before. The research advance,using a 3-dimensional array of atoms in quantum states called quantum bits—or qubits—was made by David S. Weiss, professor of physics at Penn State University, or three students on his lab team. He said "Our result is one of the many critical developments that still are needed on the way to achieving quantum computers that will be useful for doing computations that are impossible to do today,with applications in cryptography for electronic data security and other computing-intensive fields."
