Article Summary
John Martinis’ research group at the University of California at Santa Barbara has created the first quantum computer with the quantum equivalent of conventional Von Neumann architecture. This general-purpose programmable quantum computer is realized using superconducting circuits and offers greater potential for large-scale quantum computing than the one-problem devices that have been demonstrated in this emerging field to date.
