Researchers Measure Energy Needed to Change Magnetic Anisotropy of Single Cobalt Atom

Magnetic devices like hard drives, magnetic random access memories (MRAMs), molecular magnets, and quantum computers depend on the manipulation of magnetic properties. In an atom, magnetism arises from the spin and orbital momentum of its electrons.

New Level of Reliability in Five-Qubit Array Advances Progress towards Quantum Computers

A fully functional quantum computer is one of the holy grails of physics. Unlike conventional computers, the quantum version uses qubits (quantum bits), which make direct use of the multiple states of quantum phenomena. When realized, a quantum computer will be millions of times more powerful at certain computations than today's supercomputers.

Novel MRI System Helps Peer Into Atomic Structure of Individual Molecules

For decades, scientists have used techniques like X-ray crystallography and nuclear magnetic resonance imaging (NMR) to gain invaluable insight into the atomic structure of molecules, but such efforts have long been hampered by the fact that they demand large quantities of a specific molecule and often in ordered and crystalized form to be effective – making it all but impossible to peer into the structure of most molecules.

Review on Quantum Manipulation

Quantum superposition is a fundamental and also intriguing property of the quantum world. Because of superposition, a quantum system can be in two different states simultaneously, like a cat that can be both "dead" and "alive" at the same time. However, this anti-intuitive phenomenon cannot be observed directly, because whenever a classical measuring tool touches a quantum system, it immediately collapse into a classical state.
