Microsoft, Atom Computing, EeroQ update their quantum computing progress
With dozens of companies, from small startups to tech giants, pursuing quantum computing, there's a steady flow of results as they try to find a path to utility. We typically focus on new technologies and major landmarks, which can obscure the fact that any big success will inevitably have been built on a lot of incremental progress. The past few weeks have seen a number of companies release progress reports on how they're trying to get the technologies closer to general use.

Atom-based quantum computers are catching up in the race to usefulness
The race to build the first truly useful quantum computer just got more exciting. A quantum computer made from extremely cold atoms has now passed some of the most important milestones towards usefulness, joining a small group of equally able and promising machines. Though there is wide agreement that sufficiently powerful quantum computers would transform our ability to discover new materials and drugs, and break the encryption that underpins the internet, there are many competing ideas...
Chip-scale 'acoustic atom' controls sound waves to imitate atomic energy levels and advance computing
Chip-scale 'acoustic atom' controls sound waves to imitate atomic energy levels and advance computing Stephanie Baum Scientific Editor Robert Egan Associate Editor For every action, there is an equal and opposite reaction. What goes up must come down. Physical laws like these govern all of the natural world—except for the tiny internal components of today's microprocessors, which operate according to the unique and complicated rules of quantum physics.
China unveils first-of-its-kind 'dual-core' quantum computer — its makers say it improves stability and efficiency
China unveils first-of-its-kind 'dual-core' quantum computer — its makers say it improves stability and efficiency A new Chinese quantum computing system pairs two independent neutral-atom arrays in one processor, aiming to boost stability, efficiency and scalability. A Chinese company has unveiled what its researchers are calling the world’s first "dual-core" quantum computer. It's a neutral-atom system designed to improve stability, efficiency and error correction by pairing two...
New light-powered chip could accelerate AI and quantum computing
New light-powered chip could accelerate AI and quantum computing - Date: - June 2, 2026 - Source: - Monash University - Summary: - Scientists have created a tiny chip that can generate, steer, and read light-based information all in one device, marking a major leap toward ultra-fast, energy-efficient computing. The breakthrough uses atomically thin materials and nanoscale structures to control a unique quantum property of light called the “valley” degree of freedom, allowing information to...
Symmetry-Protected Quantum Computing using Metamaterials
Announce Type: cross Abstract: We propose a new architecture for practical quantum computing that combines three established principles: symmetry protection of relative-motion qubits via the generalized Kohn theorem, control via twisted-light orbital angular momentum, and metamaterial nanofocusing (e.g. using Weyl-semimetal plasmonics). Crucially, the core mechanism is generic: it applies to any current or future quantum computing system involving parabolic confinement, including cold atoms,...

Development of a 3D-CNN-based Prediction Model for Migration Barriers in Plasma-Wall Interactions
arXiv:2604.05521v2 Announce Type: replace Abstract: Understanding the long-term transport of hydrogen isotopes in plasma-facing materials, such as tungsten, is critical for the steady-state operation of magnetic confinement fusion reactors. However, dynamically updating the transition parameters for kinetic Monte Carlo (kMC) simulations as the atomic structure evolves under continuous plasma irradiation remains a severe computational bottleneck. Conventionally, calculating these migration...
Quantum error correction with the toric code
arXiv:2606.04079v1 Announce Type: cross Abstract: Quantum computing platforms based on arrays of tweezer-confined neutral atoms have recently emerged as a competitive modality thanks to a direct path toward high qubit count, rapidly advancing operation fidelities, and their ability to execute circuits with arbitrary qubit connectivity. These features will enable the use of efficient error correction schemes with high encoding-rates, time-efficient decoding, and resource-efficient...
