Quantum Newton’s cradle set to level up computing

July 23, 2026 Sending quantum information through a chain of qubits, like energy through a Newton’s cradle, could be the key to faster operations and take quantum computing to the next level. Read the full article →

Simple circuit brings topological insulators closer to practical electrical measurement standards

July 23, 2026 Researchers at the University of Würzburg have succeeded in detecting exceptionally robust electrical transport in a topological insulator. This could lead to new metrological applications. The work is published in the journal Nature Communications. Read the full article →

Engineers observe quantum heat waves at room temperature

July 23, 2026 Efficient heat management in solids is key to advancing the next generation of electronics. However, wave-like heat movement—known as phonon focusing—had been observed only at extremely low, or cryogenic, temperatures, limiting its study and practical use. Read the full article →

World’s first ‘zinc oxide spin qubit’ could advance scalable quantum devices

July 24, 2026 A research team led by SKKU professor Hosung Seo of the Department of Quantum Information Engineering and the SKKU Advanced Institute of Nanotechnology, working with the University of Wisconsin–Madison and the University of Washington, has identified—for the first time—an atomic defect structure in the zinc oxide (ZnO) semiconductor with outstanding properties for

Quantum Zeno effect could freeze computations as qubit systems scale up

July 24, 2026 The promise of quantum computing is to solve complex problems faster and more energy-efficiently than today’s supercomputers—from optimizing logistics to simulating molecules. This goal is coming within reach as the number of qubits—the computational units of quantum computing—increases. Read the full article →

Near a black hole, gravity changes a quantum circuit’s readings, not its rules

July 26, 2026 Imagine holding one of our most precise quantum devices at a fixed position outside a black hole. A Josephson junction—two superconductors separated by an ultrathin barrier—can turn a voltage into a quantum oscillation with extraordinary precision. Would intense gravity change that quantum rule, or only change how a faraway observer reads the

A quantum heat engine that simultaneously provides work and refrigeration

July 26, 2026 The laws of thermodynamics state that heat naturally flows from hotter systems or regions to colder systems or regions until a state of thermal equilibrium is reached. This simple principle underpins the operation of numerous technologies, ranging from refrigerators to power plants. Read the full article →

Long-lived ytterbium states could sharpen quantum computing and atomic clocks

July 24, 2026 Researchers from the University of Amsterdam and the University of New South Wales have answered a question that has been around for decades: whether ions of the metal ytterbium can enter certain long-lived, nearly stable states and, if so, for how long. The measured long-lived states may find applications in quantum computers

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 →

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.
