Researchers at the University of Lincoln, UK, have collaborated with the Universities of St. Andrews, Oxford and University College London to develop a new material that could help to make quantum computers more energy efficient.
The co-authored paper, ‘Distance Measurement of a Noncovalently Bound Y@C82 Pair with Double Electron-Electron Resonance Spectroscopy’, discusses how the group developed a new system based in endohedral fullerenes that can be used in the next generation of quantum computers.
Quantum computers use Quantum Bits (Qbits), instead of bits as their processing unit. Qbits require very low temperatures to maintain their quantum properties and once these properties are depleted, their advantage over normal bits is lost.
Currently, technologies for quantum computers rely heavily on maintaining the whole system at temperatures close to absolute zero (~0 K). This requires very advanced and expensive to maintain instrumentation, which keeps quantum computers as prototypes that only a few companies have developed.
The group spoke about the new find and said: “This research could take quantum technologies development to the next level creating materials that require temperatures in the range of 50-60 Kelvin, instead of milliKelvin as is currently required. We’re already looking at expanding this technology and probe one of the fundamental requirements for making a quantum computer: Spin entanglement.”
The co-authored paper was published in Journal of American Chemical Society and can be read online.
