Patterns in chaos have been proven, in the incredibly tiny quantum realm, by an international team co-led by UC Santa Cruz physicist Jairo Velasco, Jr. In a new paper published on November 27 in Nature, the researchers detail an experiment that confirms a theory first put forth 40 years ago stating that electrons confined in […]

A team experimentally observed higher-order and fractional discrete time crystals (DTCs) in periodically driven Rydberg atomic dissipative systems. Their study was published in Nature Communications. The team was led by Prof. Ding Dongsheng from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences.

High harmonic generation (HHG) is a highly non-linear phenomenon where a system (for example, an atom) absorbs many photons of a laser and emits photons of much higher energy, whose frequency is a harmonic (that is, a multiple) of the incoming laser’s frequency. Historically, the theoretical description of this process was addressed from a semi-classical […]

The deep neural network models that power today’s most demanding machine-learning applications have grown so large and complex that they are pushing the limits of traditional electronic computing hardware.

In recent years, quantum physicists and engineers have been trying to develop quantum computer processors that perform better than classical computers on some tasks. Yet conclusive demonstrations proving that quantum systems perform better than their classical counterparts (i.e., realizations of a quantum advantage) remain scarce, due to various experimental challenges.

Over the past few years, some researchers have been working on alternative energy storage systems that leverage the principles of quantum mechanics. These systems, known as quantum batteries, could be more efficient and compact than conventional battery technologies, while also achieving faster charging times.
