In close collaboration with our UNSW colleagues, we apply this method to the fabrication of quantum computer devices containing few or single atoms in which single electron spins can be controlled and read - out.

This image shows how «spintronics» researchers such as David Awschalom probe and manipulate single electron spins in semiconductors.

Each quantum dot consists of coupled spherical quantum wells, each in turn containing a single electron spin.

Not exact matches

Each hydrogen atom, made up of just a single proton and electron, can be found in two slightly different states: a higher energy state in which the electron and proton essentially spin in the same direction, and a lower energy state in which they spin in opposite directions.

In a technique that could help silicon quantum computers scale up, a particle of light (pink waves) was made to interact with the spin of a single electron (pink circle).

In terms of applications, it's quite possible that the team's work with double - dot SETs will find future use within quantum electronics to manipulate a single electron and its spin.

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.

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.

Two examples: graphene — single - atom - thick sheets of carbon atoms — has unique mechanical, electrical, and optical properties; and two - dimensional electron gases (2DEG)-- planar collections of electrons supported at the interface between certain semiconductors such as gallium arsenide — allow the observation of such emergent behaviors as the quantum Hall effect and the spin Hall effect.

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.
