Quantum Measurement Unlocks W-State Entanglement Researchers at Kyoto University and Hiroshima University have experimentally demonstrated an entangled measurement that identifies multi-photon W states, solving a challenge open for more than 25 years. The method uses cyclic shift symmetry and a photonic quantum circuit performing a quantum Fourier transform to distinguish three-photon W states in a … Read more
Starship Reaches Orbit for First Time SpaceX’s Starship completed its first orbital flight on 28 September 2026 during its 14th integrated test. The vehicle launched from Starbase, Texas, reached a roughly 275 km orbit despite an early Raptor engine shutdown on the upper stage, deployed 26 next-generation Starlink V3 satellites, and returned after about three … Read more
Quantum Simulator Recreates Matter Formation Researchers led by Duke Quantum Center used a 13-ion trapped-ion quantum simulator to observe string-breaking dynamics, in which energy buildup between simulated particles causes new particle-antiparticle pairs to effectively pop into existence. The work, published in Nature Physics and covered this weekend, recreates a process normally seen only in extreme … Read more
Holographic Nature of Gravity A Quanta Magazine analysis published September 25 examines the holographic principle as modern theoretical physics’ biggest breakthrough: gravity can make the contents of any spatial region fully equivalent to information on its boundary surface. This collapses the distinction between volume and area, implying space itself may emerge from quantum information. The … Read more
Time Crystals Synchronize Across a Semiconductor Physicists at TU Dortmund University have shown that multiple continuous time crystals inside a gallium arsenide semiconductor can lock their electron-nuclear spin oscillations to a shared frequency. The effect, reported in Nature Communications and highlighted on 24 September 2026, occurs when a broad laser beam illuminates separate regions, coupling … Read more
First Real-Time Quantum Jumps Observed in Sound Stanford researchers have recorded the first direct, real-time observation of quantum jumps in sound. Using a chip-scale mechanical resonator coupled to a superconducting qubit, the team watched individual phonons—discrete quanta of vibrational energy—abruptly transition from the one-phonon excited state to the ground state. The findings, published in Science, … Read more
Quantum Jumps of Sound Observed in Real Time Stanford researchers have recorded the first real-time quantum jumps of individual phonons—quanta of sound—in a mechanical resonator. A microscopic device coupled to a superconducting qubit showed a vibration abruptly dropping from one energy quantum to zero, rather than fading continuously. The result, published in Science and highlighted … Read more
Roman Telescope’s 300-Megapixel Camera Comes Online NASA’s Nancy Grace Roman Space Telescope has successfully powered up its Wide Field Instrument, a 300-megapixel infrared camera, while en route to the Sun-Earth L2 point. The activation, following cooling of its 18 detectors to operating temperatures near –143 °C, and early checks of the Coronagraph Instrument mark a … Read more
NIST Measurement Deepens Gravity Constant Puzzle A decade-long NIST experiment measuring the gravitational constant G has yielded a value 0.0235% lower than a leading 2007 French BIPM result, after researchers unsealed a blinding envelope containing a secret offset. The team used a torsion balance with copper and sapphire masses, combining free-deflection and electrostatic-servo methods, reporting … Read more
Graph Sandwich Conjecture Resolved Mathematicians have completed a decades-old proof showing that large random regular graphs can be rigorously “sandwiched” between two simpler random binomial graphs. The result, detailed on 18 September, lets researchers transfer many known properties of easy-to-analyze binomial graphs directly onto the harder regular graphs that better model real networks. It stands … Read more
