Supercomputers without waste heat

12.12.2018 | University of Konstanz | www.uni-konstanz.de

Generally speaking, magnetism and the lossless flow of electrical current (superconductivity) are competing phenomena that cannot coexist in the same sample. However, for building supercomputers, synergetically combining both states comes with major advantages as compared to today’s semiconductor technology, which has come under pressure due to its high power consumption and resulting heat production.

Researchers from the Department of Physics at the University of Konstanz have now demonstrated that the lossless electrical transfer of magnetically encoded information is possible. This finding enables enhanced storage density on integrated circuit chips and, at the same time, significantly reduces the energy consumption of computing centres. The results of this study have been published in the current issue of the scientific journal Nature Communications.

Supercomputers

A collaboration at the University of Konstanz between the experimental physics group led by Professor Elke Scheer and the theoretical physics group led by Professor Wolfgang Belzig uses an approach based on dissipation-free charge transport in superconducting building blocks.
