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 →

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

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 →

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

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 →

New quantum chip architecture could use built-in vibrations to link distant qubits

July 27, 2026 A new concept from Warwick researchers could help solve one of the biggest challenges to building large-scale quantum computers: enabling communication between vast numbers of quantum bits (qubits) over long distances across a single chip. 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

Quantum neural networks get their first hardware test

July 27, 2026 Neural networks have transformed how machines find patterns in data, from recognizing faces in photos to predicting the shapes of proteins. So far, all of this progress has been made on ordinary classical computers, but with quantum computers now edging into practical use, there is a real possibility that neural networks could

Simple semiconductor films break light’s front-back symmetry

July 27, 2026 Light typically interacts with a material the same way whether it enters through the front or the back—like polarized sunglasses that work the same from either side. Cornell researchers have demonstrated a simple route to breaking that symmetry, opening new possibilities for photonics and quantum information processing. 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 →
