“Quantum computing begins where Moore’s Law ends — about the year 2020, when circuit features are predicted to be the size of atoms and molecules,” says Isaac L. Chuang, who led the team of scientists from IBM Research, Stanford University and the University of Calgary. “Indeed, the basic elements of quantum computers are atoms and molecules.”
Quantum computers get their power by taking advantage of certain quantum physics properties of atoms or nuclei that allow them to work together as quantum bits, or “qubits,” to be the computer’s processor and memory. By interacting with each other while being isolated from the external environment, theorists have predicted — and this new result confirms — that qubits could perform certain calculations exponentially faster than conventional computers.
