Manipulating the geometry of the 'electron universe' in magnets

Researchers at Tohoku University and the Japan Atomic Energy Agency have developed fundamental experiments and theories to manipulate the geometry of the "electron universe," which describes the structure of electronic quantum ...

Steering toward quantum simulation at scale

Researchers simulated a key quantum state at one of the largest scales reported, with support from the Quantum Computing User Program, or QCUP, at the Department of Energy's Oak Ridge National Laboratory.

Bounding the amount of entanglement from witness operators

A team of researchers has proposed an approach to quantify entanglement using the standard entanglement witness procedure under three common experimental scenarios. Their work is published in Physical Review Letters.

Springing simulations forward with quantum computing

Though "coupled oscillations" may not sound familiar, they are everywhere in nature. The term "coupled harmonic oscillators" describes interacting systems of masses and springs, but their utility in science and engineering ...

Internet can achieve quantum speed with light saved as sound

Researchers at the University of Copenhagen's Niels Bohr Institute have developed a new way to create quantum memory: A small drum can store data sent with light in its sonic vibrations, and then forward the data with new ...

Computing how quantum states overlap

Quantum many-body systems are things such as atomic nuclei that consist of many tiny particles moving in complex ways. This makes it extremely difficult to predict how the systems behave as the particles interact. To study ...

Simulating magnetization in a Heisenberg quantum spin chain

The rapid progress of quantum simulators is now enabling them to study problems that before have been limited to the domain of theoretical physics and numerical simulation. A team of researchers at Google Quantum AI and their ...
