• AAAS: Martinis & Freedman discuss Quantum computing at AAAS kick-off


    "John Martinis and his colleagues at the University of California, Santa Barbara (UCSB), have been trying to forge qubits from superconducting circuits. In a superconductor, electrons do not travel solo. Instead, for complicated quantum-mechanical reasons, they pair up (for the same reasons, the pairs feel no electrical resistance). When they do so, the pairs start behaving like a single particle, superposing proclivities and all. This superparticle can, for instance, in effect be moving in two directions at once. As electrons move, they create a magnetic field.
