Scientists led by Tobias Kippenberg at EPFL have now achieved the long-sought goal: they successfully prepared six mechanical oscillators in a collective state, observed their quantum behavior, and measured phenomena that only emerge when oscillators act as a group. The research, published in Science, marks a significant step forward for quantum technologies, opening the door to large-scale quantum systems.

Scientists at EPFL have made important progress in quantum technology, achieving strong coupling between quantum dots in Germanium and microwave photons, paving the way for scalable quantum computing based on spin qubits.

Optical measurement techniques are increasingly used in surgery for real-time tissue analysis. This technology is particularly important for monitoring during tumor removal, as it helps to detect any malignant cells that may still be present. These innovative techniques will also improve therapies for patients in the future. To this end, researchers from Dresden are collaborating with the Dutch company Single Quantum, which specializes in quantum technology, and Absolut System SAS, a French cryogenic engineering consultancy. They want to bring sensors that have so far only been used in quantum computing and communication to the operating room. An EU grant totaling EUR 5 million over four years is supporting the consortium in developing and implementing this technology.

Planckian, an innovator in quantum technology, today announced the release of a new blueprint for the development a superconducting quantum chip natively designed to address the wiring problem. The new chip architecture employs a cutting-edge control setup that manipulates qubits via a shared control line while at the same time selectively driving them to perform universal quantum computation.

A Japanese research team, led by Professor Dr. Toru Asahi, Researcher Dr. Kenta Nakagawa, and master’s student Keigo Tokita from the Faculty of Science and Engineering, Comprehensive Research Organization at Waseda University, investigated the origin of the strong optical anisotropy of lead-doped Bi2212 single crystals using ultraviolet and visible light transmittance measurements.

Researchers at the UChicago Pritzker School of Molecular Engineering (UChicago PME) have realized a new design for a superconducting quantum processor, aiming at a potential architecture for the large-scale, durable devices the quantum revolution demands.

Researchers at QuTech have managed to, for the first time, perform coherent logic operations between spin qubits 250 micrometers apart on the same chip. Such ‘enormous’ distances create new opportunities for operations between qubits, as they normally only sustain over 100 nm. These results hold promise for scalable networks of spin qubit islands on a chip. The researchers published their results in Nature Physics.

While atoms are known to wiggle very fast, dopants added to a cuprate superconductor can also cause atoms to meander very slowly. A SLAC study shows this process, called atomic relaxation, offers a new way to explore quantum states in these puzzling materials.

The DLR Quantum Computing Initiative (DLR QCI) of the German Aerospace Center has selected IQM Quantum Computers (IQM), a global leader in superconducting quantum computers, to develop quantum embedding algorithms for the simulation of materials science systems.

Two University of Rhode Island physics professors have been awarded separate $800,000 grants as part of the National Science Foundation’s $39 million program to grow quantum research at institutions of higher education across the U.S.
