Today, physicists are still asking themselves whether quantum mechanics needs hypercomplex numbers. FAU researchers Ece Ipek Saruhan, Prof. Dr. Joachim von Zanthier and Dr. Marc Oliver Pleinert have been investigating this question in their research.

Led by Professor Pasquale Scarlino at EPFL, they developed a superconducting Kerr resonator, a device with controllable quantum properties, and engineered it to experience a two-photon drive, which sends pairs of photons into the system to carefully control its quantum state and study how it transitions between different phases.

Working at nanoscale dimensions, billionths of a meter in size, a team of scientists led by the Department of Energy’s Oak Ridge National Laboratory revealed a new way to measure high-speed fluctuations in magnetic materials. Knowledge obtained by these new measurements, published in Nano Letters, could be used to advance technologies ranging from traditional computing to the emerging field of quantum computing.

FormFactor, Inc., a leader in precision test and measurement solutions, and Delft Circuits, an innovator in high-density cryogenic cabling solutions, have teamed up to integrate Delft Circuits’ Cri/oFlex® product portfolio into FormFactor’s cryogenic test systems. This partnership addresses the growing demand for scalable, high-density interconnect solutions in quantum computing, enabling the industry to meet growing demands for computation power and efficient system interfacing.

Oxford Instruments NanoScience today introduces its low temperature, superconducting magnet measurement system for fundamental materials physics, TeslatronPT Plus. The system promises simpler access to high performance measurement capabilities, allowing users to spend more time on the measurement rather than the set-up, while gaining a flexible, scalable and secure system.

UC Santa Barbara researchers are working to move cold atom quantum experiments and applications from the laboratory tabletop to chip-based systems, opening new possibilities for sensing, precision timekeeping, quantum computing and fundamental science measurements.

Now, a series of experiments has clearly demonstrated that this instantaneous effect of neutron bombardment, known as the “beam on effect,” should not be an issue during reactor operation, thus clearing the path for projects such as the ARC fusion system being developed by MIT spinoff company Commonwealth Fusion Systems.

University of Arizona College of Engineering researchers Christos Gagatsos and Bane Vasic received two grants from the federal government to advance novel areas in quantum information. Gagatsos was awarded $1.4 million from the U.S. Army Research Office to investigate the application of quantum error correction in magnetic field sensing, and Vasic was awarded $600,000 from the National Science Foundation to stabilize quantum computing with error correction codes.

The Photonics and Quantum Sensing Technology Lab at IIT Bombay is ready with some technologies that can give the newly initiated Quantum Sensing and Metrology Hub a kick start into the world of quantum technologies.

Silicon is the best-known semiconductor material. However, controlled nanostructuring drastically alters the material's properties. Using a specially developed etching apparatus, a team at HZB has now produced mesoporous silicon layers with countless tiny pores and investigated their electrical and thermal conductivity. For the first time, the researchers elucidated the electronic transport mechanism in this mesoporous silicon. The material has great potential for applications and could also be used to thermally insulate qubits for quantum computers.
