A team of researchers, led by scientist Lin Zhou of Ames National Laboratory, has made important progress towards understanding the role of surface oxides in improving quantum computing circuits performance. Surface oxides are a primary cause of decoherence, or loss of quantum properties in quantum circuits. The team is part of a larger effort by the Superconducting Quantum Materials and Systems Center (SQMS) to improve quantum computers.

The University of Basel and QuantumBasel have agreed to collaborate to further develop the Center for Quantum Computing and Quantum Coherence (QC2) at the Department of Physics into a leading center of excellence for quantum computing and to strengthen the bridge between cutting-edge research and industrial applications in quantum computing. This partnership will enhance the cluster of quantum research in the Basel region and drive the development of quantum algorithms and their practical application. This will strengthen Switzerland's position in the international race for the leading role in technology.

Researchers from the Department of Energy’s Oak Ridge National Laboratory have taken a major step forward in using quantum mechanics to enhance sensing devices, a new advancement that could be used in a wide range of areas, including materials characterization, improved imaging and biological and medical applications.

A paper recently published in Nature Communications from UChicago PME’s High Lab and Argonne National Laboratory has solved a major hurdle facing researchers working with diamond by creating a novel way of bonding diamonds directly to materials that integrate easily with either quantum or conventional electronics.

In a Nature Reviews Physics perspective article, researchers overview the latest advances regarding quantum phenomena within attosecond science, which are often overlooked despite their potential to influence experimental and theoretical outcomes.

Physicists from the University of Basel have succeeded in coupling two Andreev qubits coherently over a macroscopic distance for the first time. They achieved this with the help of microwave photons generated in a narrow superconducting resonator. The results of the experiments and accompanying calculations were recently published in Nature Physics, laying the foundation for the use of coupled Andreev qubits in quantum communication and quantum computing.

University of Waterloo researchers have successfully demonstrated the ability to measure and reset a trapped ion qubit to a known state without disturbing neighbouring qubits just a few micrometres away — a distance smaller than the width of a human hair, which is about 100 micrometres thick.

In a first for Germany, researchers at the Karlsruhe Institute of Technology (KIT) have shown how so-called tin vacancies in diamonds can be precisely controlled using microwaves. These vacancies have special optical and magnetic properties and can be used as qubits, the smallest computational units for quantum computing and quantum communication. The results are an important step for the development of high-performance quantum computers and secure quantum communications networks. T

In the CiRQus project, we have implemented laser-controlled interactions between a highly-excited circular Rydberg qubit and a second ionic core electron. This achievement advances control of circular Rydberg atoms from the microwave to the optical domain by combining established tools for manipulating trapped ions with neutral atom arrays.

A breakthrough in quantum technology research could help realise a new generation of precise quantum sensors that can operate at room temperature. The research—carried out by an international team of researchers from the University of Glasgow, Imperial College London, and UNSW Sydney—shows how the quantum states of molecules can be controlled and sensitively detected under ambient conditions.
