Scientists at the Institute of Physics of the University of Tartu have found a way to develop optical quantum computers of a new type. Central to the discovery are rare earth ions that have certain characteristics and can act as quantum bits. These would give quantum computers ultrafast computation speed and better reliability compared to earlier solutions. The University of Tartu researchers Vladimir Hizhnyakov, Vadim Boltrushko, Helle Kaasik and Yurii Orlovskii published the results of their research in the scientific journal
The vacuum solutions provider today (10
th Dec) said it was awarded the contract from TU Darmstadt who will use the system in its Collinear Apparatus for Laser Spectroscopy and Applied Physics, large-scale research facility.
For the experiment, the EBIS-A type ion source used will generate electrically charged ions of light chemical elements which will be coupled into the beamline of the COALA apparatus. A clean ultra-high vacuum is essential to ensure the particles can move as freely as possible in the beamlines.
An extremely powerful and reliable vacuum generator is necessary to maintain such a low pressure. This is even more so in the case of the new ion source since the ions remain in this for a much longer time.
