X-rays visualize how one of nature’s strongest bonds breaks
Uppsala University

The use of short flashes of X-ray light brings scientists one big step closer toward developing better catalysts to transform the greenhouse gas methane into a less harmful chemical. The result, published in the journal Science, reveals for the first time how carbon-hydrogen bonds of alkanes break and how the catalyst works in this reaction.

Axions whisper, but can you hear them? FAMU-FSU College of Engineering researchers think so
Florida State University

Researchers at the FAMU-FSU College of Engineering are working with scientists from the Axion Dark Matter Experiment (ADMX) team at Lawrence Livermore National Laboratory (LLNL) on a U.S. Department of Energy project to develop particle detectors that are sensitive enough to find these particles.

The 'breath' between atoms — a new building block for quantum technology
University of Washington

University of Washington researchers have discovered they can detect atomic "breathing," or the mechanical vibration between two layers of atoms, by observing the type of light those atoms emitted when stimulated by a laser. The sound of this atomic "breath" could help researchers encode and transmit quantum information.

Understanding the Tantalizing Benefits of Tantalum for Improved Quantum Processors
Brookhaven National Laboratory

Researchers working to improve the performance of superconducting qubits, the foundation of quantum computers, have been experimenting using different base materials in an effort to increase the coherent lifetimes of qubits. The coherence time is a measure of how long a qubit retains quantum information, and thus a primary measure of performance. Recently, scientists discovered that using tantalum in superconducting qubits makes them perform better, but no one has been able to determine why—until now.

Quantum scientists accurately measure power levels one trillion times lower than usual
Aalto University

Scientists in Finland have developed a nanodevice that can measure the absolute power of microwave radiation down to the femtowatt level at ultra-low temperatures – a scale trillion times lower than routinely used in verifiable power measurements. The device has the potential to significantly advance microwave measurements in quantum technology.

Curved spacetime in a quantum simulator
Vienna University of Technology

The theory of relativity works well when you want to explain cosmic-scale phenomena - such as the gravitational waves created when black holes collide. Quantum theory works well when describing particle-scale phenomena - such as the behavior of individual electrons in an atom.

Seeing electron orbital signatures
University of Texas at Austin (UT Austin)

No one will ever be able to see a purely mathematical construct such as a perfect sphere. But now, scientists using supercomputer simulations and atomic resolution microscopes have imaged the signatures of electron orbitals, which are defined by mathematical equations of quantum mechanics and predict where an atom’s electron is most likely to be.

Columbia University School of Engineering and Applied Science

Columbia Engineering researchers have developed a new class of integrated photonic devices--“leaky-wave metasurfaces”--that convert light initially confined in an optical waveguide to an arbitrary optical pattern in free space. These are the first to demonstrate simultaneous control of all four optical degrees of freedom, setting a world record. Because they’re so thin, transparent, and compatible with photonic integrated circuits, they can be used to improve optical displays, LIDAR, optical communications, and quantum optics.
