Today, this behaviour is very well understood at the microscopic level: magnetism goes back to the angular momentum — the spin — of the electrons in the outer shell of the atoms that build up a solid state crystal.
This bound spin - direction state is like our electron's bicycle, keeping it rolling along powerfully enough to overcome bumps in the one - dimensional road.»
But because electron spins offer one of the most promising models for quantum bitsphysical states that can store far more information than conventional computer bitsscientists have sought ways around the coherence problem.

QSLs are strange states achieved in solid materials where the magnetic moments, or «spins,» associated with electrons exhibit a fluidlike behavior.
But thanks to an eerie quantum effect known as superposition — which allows an atom, electron or other particle to exist in two or more states, such as «spinning» in opposite directions at once — a single qubit made of a particle in superposition can simultaneously encompass both digits.
Now researchers at the University of Utah, The Florida State University, University College London and the University of Sydney in Australia report a way to extend that informational lifetime to more than 100 seconds by encoding an electron's spin onto the much longer - lived spin of an atomic nucleus, which can then be read out electronically.
The left diagram depicts the spin - blockaded biexciton state that relaxes into a dark exciton and produces a photon; solid circles are electrons while empty ones are holes.
The researchers used a technique called inelastic electron tunneling spectroscopy to probe the quantum spin states of a single cobalt atom bound to an MgO layer.

He adds that the very difficult next step would be to find a way to bind together the spin states of multiple electrons within these wells.
Controlling the electron spins without destroying the coherent quantum states has proven difficult with other techniques, but a series of experiments by the group has shown the quantum states remain solid.
Electrons and nuclei can act like tiny bar magnets with a spin that is assigned a directional state of either «up» or «down.»
That's because in the excited state, two electrons waltz through the molecule, spinning like tops, and only when the electron spins point in opposite directions does the dance end with the release of a photon.
In this approach, a qubit» 0» state is defined when the spin of the electron is down and the nucleus spin is up, while the» 1» state is when the electron spin is up, and the nuclear spin is down.
