Major Step Forward for Quantum Technology


Major Step Forward for Quantum Technology
A team of researchers from Finland, Sweden, and Japan have developed a semiconductor component in which quantum information can be efficiently exchanged between electron spin and photons at room temperature and above. The new method, described in an article recently published in Nature Photonics, is based on amplifying the spin polarisation in a semiconductor structure made up of InAs quantum dots and nitrogen-containing semiconductor compounds. The component was fabricated by researchers at Tampere University using the molecular beam epitaxy (MBE) technique.
“Conventional electronics carry and store information using transistors that switch between states, controlled by electrons with a negative charge. This technology is seeing its limits in terms of processing speed and capacity, as well as energy needs (a major example is the huge increase of electricity dema ....

The use of information technology in which the spin of electrons is used for information processing in quantum computers might be possible in the future. For a long time, this has been the aim of researchers to use spin-based quantum information technology at ambient temperature.

Now, scientists from Sweden, Finland and Japan have built a semiconductor component where information can be efficiently exchanged between light and electron spin at ambient temperature and above.
The fact that electrons feature a negative charge is well known, and they also exhibit another property called spin. The latter might be instrumental in the development of information technology. In simple terms, the electron can be visualized to rotate around its own axis, analogous to how the ....
