Rare-earth ions could enable telecom-ready control of interacting qubits

July 29, 2026 Quantum technologies are devices and systems that exploit the laws of quantum mechanics and could perform tasks that are difficult or impossible to tackle using their classical counterparts. These technologies process and store information using qubits (i.e., quantum bits), which can exist in a superposition of multiple states simultaneously. Read the full

New research shows how ‘hot electrons’ can reshape metals in billionths of a second

July 28, 2026 Researchers at The University of Manchester have revealed how intense electronic excitation can trigger rapid structural changes in metals—without heating the atomic lattice—offering new insight into ultrafast materials behavior. Read the full article →

A way to read quantum bits faster and with less hardware

July 28, 2026 Quantum computers process information in a fundamentally different way from conventional computers, using quantum bits, or qubits, that can exist in multiple states at once. This could allow them to tackle problems beyond the reach of today’s machines, from simulating new materials to optimizing complex systems. Read the full article →

Quantum spin effects may enhance one-way electrical transport in chiral magnets

July 30, 2026 Quantum fluctuations influence direction-dependent electrical transport in chiral magnets, researchers from Science Tokyo report. In chiral magnetic systems, electric current flows differently depending on its direction, but the role of quantum effects in this behavior has remained unclear. Through theoretical analysis, the researchers showed that chiral magnetic systems exhibit logarithmic temperature dependence

Cesium atoms and quantum dots generate indistinguishable photons for modular quantum networks

July 30, 2026 Large-scale quantum communication networks require both reliable quantum memories and coherent single-photon sources that can exchange quantum information efficiently. A coherent source of single photons with narrow linewidth, high brightness, spectral uniformity and compatibility with quantum memories is necessary. While a variety of single-photon sources, such as quantum dots (QDs) and atoms

Light’s hidden properties save quantum information from the chaos of bad weather

July 30, 2026 For years, researchers have tried to harness the “twist” of light to transmit data. This property describes how light spirals as it travels forward, and because it can be molded into a virtually infinite number of different twists, it provides a massive, promising alphabet for high-capacity communication.

Physicists link the Riemann Hypothesis to phase transitions in quantum systems

July 30, 2026 A new study in Nature Communications has established a link between the Riemann Hypothesis and dynamical phase transitions in engineered quantum systems, demonstrating the effect on a quantum processor. Read the full article →

Quantum computer completes verified task beyond practical reach of classical simulations

August 1, 2026 IBM and researchers from the University of Chicago announced a demonstration in quantum computing that meets the fundamental criteria for “quantum advantage”—the point where quantum computers can be confirmed to have outperformed classical computers on trusted computations.

Diamond’s newfound defect may tame vibrations that hinder quantum light sources

July 31, 2026 Researchers in the Department of Electrical and Computer Engineering at the University of Illinois Urbana-Champaign have discovered a new type of quantum light emitter in diamonds that could help overcome a number of challenges facing quantum technologies. Read the full article →

Less-explored form of quantum code could be more powerful—and more stable—than its alternative in error correction

July 31, 2026 In mathematics and getting dressed, some processes are commutative, while others are noncommutative. Commutative means the order doesn’t matter (3 + 2 is the same as 2 + 3, and it doesn’t matter which sock goes on first). Noncommutative means the order does matter. Read the full article →
