Further Improvement of Qubit Lifetime for Quantum Computers
Jülich, 8 December 2016 – An international team of scientists has succeeded in making further improvements to the lifetime of superconducting quantum circuits. An important prerequisite for the realization of high-performance quantum computers is that the stored data should remain intact for as long as possible. The researchers, including Jülich physicist Dr. Gianluigi Catelani, have developed and tested a technique that removes unpaired electrons from the circuits. These are known to shorten the qubit lifetime.

Today’s tunable dielectric with the highest figure of merit at room temperature and GHz frequencies is strained films of (SrTiO3)6SrO. The low loss at frequencies up to 125 GHz comes from the defect mitigating nature of the (SrTiO3)nSrO Ruddlesden-Popper structure; the tunability arises from imposing strain and dimensionality to induce a ferroelectric instability.
