Using supercold environments and a quantum computer, Purdue researchers examined the evolution of a network of Ising spins in the presence of a transverse field. Much like ripples on water, the wave moves across the surface, but the water molecules move up and down, perpendicular to the wave's direction. This type of computational discovery is challenging with conventional or even supercomputers. This discovery, led by Arnab Banerjee, an assistant professor at Purdue University's Department of Physics and Astronomy, has been published in Nature Communications.

If you’d like to solve a math problem on a good old-fashioned chalkboard, you want the board clean and free of any previous markings so that you have space to work. Quantum computers have a similar need for a clean workspace, and a team including scientists at the National Institute of Standards and Technology (NIST) and University of Maryland have found an innovative and effective way to create and maintain it.

A research team led by The Hong Kong University of Science and Technology (HKUST) has achieved a groundbreaking quantum simulation of the non-Hermitian skin effect in two dimensions using ultracold fermions, marking a significant advance in quantum physics research.

In a new study, researchers from the Max Planck Institute of Quantum Optics under the lead of Timon Hilker demonstrated evidence of stripe formation, i.e. extended structures in the density pattern, in a cold-atom Fermi-Hubbard system. By using a quantum gas microscope and a special mixed-dimensional geometry, they were able to observe unique higher-order correlations in spin and charge densities related to those seen in some high-temperature superconducting materials. These findings, which shed light on a key phenomenon in condensed matter physics, suggest that individual stripe structures could form at higher temperatures than the much-debated stripe phase. This experiment represents a major step forward in using quantum simulators to explore the most fundamental properties of materials. The work is published this week in Nature.

Recently, a research team led by Prof. LI Chuanfeng from the University of Science and Technology of China (USTC) achieved a breakthrough in quantum photonics.

Airbus and BMW Group have pushed quantum computing forward another step to leverage its significant potential for future mobility solutions. At Q2B, the companies have unveiled the winners of the Quantum Computing Challenge, an international initiative to identify and mature quantum solutions for the most promising mobility applications.

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.

Oxford Ionics, a world leader in trapped-ion quantum computing, today announced it is working together with Quanscient, a leading provider of multiphysics simulation software, and aerospace manufacturer Airbus to develop quantum simulations for computational fluid dynamics.
