A functional quantum computer is one of the most intriguing promises of quantum technology. With significantly increased computing power, quantum computers will be able to solve tasks that conventional computers cannot handle, such as understanding and inventing new materials or pharmaceuticals as well as testing the limits of cryptographic techniques. In order to reduce error rates and provide reliable operations much faster, researchers at Leibniz University Hannover and Physikalisch-Technische Bundesanstalt (PTB) have developed a new method based on trapped ions. Their findings have been published in the latest issue of the scientific journal “Physical Review Letters”.

Scientists from the Physikalisch-Technische Bundesanstalt (PTB) have implemented a novel pressure measurement method, quasi as a byproduct of the work on the "new" kelvin. In addition to being new, this procedure is a primary method, i.e. it only depends on natural constants. As an independent method, it can be used to check the most accurate pressure gauges, for which PTB is known as the world leader. Checking such instruments was formerly possible in the range of up to 100 000 pascals only; now 7 million pascals are feasible. A comparison between mechanical and electrical pressure measurements has thus been carried out for the first time with a relative uncertainty of less than 5 × 10-6. Moreover, this new method offers unique possibilities to investigate helium – an important model system for the fundamentals of physics. The scientists have reported their work in the current issue of Nature Physics.
