Research Breakthrough in Entanglement Could Lead to High-Dimensional Encoding of Quantum Information, Future Quantum Devices

Quantum entanglement—or what Albert Einstein once referred to as “spooky action at a distance”— occurs when two quantum particles are connected to each other, even when millions of miles apart. Any observation of one particle affects the other as if they were communicating with each other. When this entanglement involves photons, interesting possibilities emerge, including entangling the photons’ frequencies, the bandwidth of which can be controlled.

Making Quantum Devices With Higher-Dimensional Topological States

Linked Weyl surfaces, a novel type of topological phase that exists in five-dimensional space, were experimentally observed for the first time by a team led by Professor Shuang ZHANG from the Department of Physics at The University of Hong Kong(HKU). The work provides a unique platform for exploring various topological phases, the transition between them, and the corresponding boundary effects in five dimensions. The research paper was recently published in the renowned journal Science.

Uranium Ditelluride as a Topological Superconductor

Scientists on the hunt for an unconventional kind of superconductor have produced the most compelling evidence to date that they’ve found one. In a pair of papers, researchers at the University of Maryland’s (UMD) Quantum Materials Center (QMC) and colleagues have shown that uranium ditelluride displays many of the hallmarks of a topological superconductor–a material that may unlock new ways to build quantum computers and other futuristic devices.
