Then for the bizarre part: Atom C, because it was previously entangled with B, became imprinted with atom A's
information — in this case, a pattern in the
spin of its
electrons.
Such research could lead to smaller and more efficient electronic gadgets that use

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.
But
electron spins tend to have quite brief usable lifetimes; even in optimal conditions — in pure samples held just a hair above absolute zero — the
information encoded on an
electron spin is lost on timescales
of seconds, if that.
Spintronics exploits the intrinsic
spins of electrons and their resulting magnetic properties in material, as well as the
electrons electrical charge, to store and process
information.
Making use
of electron spin for
information transmission and storage, enables the development

Lovett and his colleagues have shown that quantum
information can be transferred from an
electron's
spin to the
spin of an atomic nucleus, where it can be stored more effectively — creating a form
of «quantum memory».
Spintronics does not only make use
of the
electron's charge to transmit and store
information but it takes also advantage
of the
electron's
spin.
«Most schemes for quantum
information processing require you to electrically tune the
spin of the
electron.»
This could make the materials beneficial for
spin - related electronics, which would use the orientation
of the
electron spin to encode
information, thereby opening up a whole new realm
of computer technology.
Another radical approach is called spintronics, which relies on
information being transmitted within a chip using a property
of electrons called
spin.
Details
of the breakthrough have been published in the journal Nature Communications and its authors predict that these types
of sensors, dubbed «gate sensors», will be used in quantum computers
of the future to read
information stored in the charge or
spin of a single
electron.
For example, wires with Majoranas at either end can be used to transfer
information between far away quantum bits that rely on the
spin of electrons.
Topological insulators preserve the direction
of an
electron spin as it travels along the surface, allowing a
spin to carry bits
of information in a future quantum network.
This last property is
of interest for the development
of new magnetic memory devices, because the
spin of the
electron can be used to store and transfer
information.
In a significant step forward for quantum computing in silicon - the same material used in today's computers — a team led by researchers at Princeton University successfully coupled a single
electron's quantum
information, or
spin, to a particle
of light, or photon.
