Physicists from Skoltech have invented a new method for calculating the dynamics of large quantum systems. Underpinned by a combination of quantum and classical modeling, the method has been successfully applied to nuclear magnetic resonance in solids.  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.
