Engineers at the University of New South Wales (UNSW) have announced the invention of a "radical" architecture for quantum computing, essentially allowing quantum bits (qubits) -- the basic unit of information in a quantum computer -- to be placed hundreds of nanometres apart and still remain coupled. The invention is based on novel "flip-flop qubits" that UNSW said promises to make the large-scale manufacture of quantum chips dramatically cheaper and easier. To operate the flip-flop qubit, researchers need to pull the electron away from the nucleus, using the electrodes at the top; doing so creates an electric dipole. The conceptual breakthrough is the creation of an entirely new type of qubit using both the nucleus and the electron. The new chip design allows for a silicon quantum processor that can be scaled up without the precise placement of atoms required in other approaches.
