This allowed the researchers to explore quantum tunneling, a phenomenon often used in undergraduate chemistry courses to demonstrate one of the "spookinesses" of quantum mechanics, Field says.  Measurements at the attosecond scale not only add an extra dimension for the future quantum technologies but also can fundamentally help in understanding the elephant of the quantum room: what is time?  Physicists have proposed an entirely new way to test the quantum superposition principle-the idea that a quantum object can exist in multiple states at the same time.  Researchers have developed a new device that can measure and control a nanoparticle trapped in a laser beam with unprecedented sensitivity.  Researchers have discovered a 'blind spot' in atomic force microscopy-a powerful tool capable of measuring the force between two atoms, imaging the structure of individual cells and the motion of biomolecules.  Australian scientists have investigated new directions to scale up qubits-utilising the spin-orbit coupling of atom qubits-adding a new suite of tools to the armory.  A team of international researchers led by engineers from the National University of Singapore (NUS) have invented a new magnetic device to manipulate digital information 20 times more efficiently and with 10 times more stability than commercial spintronic digital memories.  Working in the lab of Mikhail Lukin, the George Vasmer Leverett Professor of Physics and co-director of the Quantum Science and Engineering Initiative, Evans is lead author of a study, described in the journal Science, that demonstrates a method for engineering an interaction between two qubits using photons.  Researchers with the Department of Energy's Oak Ridge National Laboratory have demonstrated a new level of control over photons encoded with quantum information.  Researchers from Intel Corp. and the University of California, Berkeley, are looking beyond current transistor technology and preparing the way for a new type of memory and logic circuit that could someday be in every computer on the planet.
