July 13, 2026• Physics 19, 91 Two independent groups have demonstrated ways to entangle quantum bits without the need for precisely timed control pulses. Figure 1: Two entangled qubits driven by a microwave signal. Figure 1: Two entangled qubits driven by a microwave signal. × Quantum entanglement describes a link, or correlation, between the states of two or more quantum particles.

Processing math: 100% July 10, 2026• Physics 19, 102 Decades-old experiments have now been enlisted to set new bounds on the properties of a hypothetical particle that bears a tiny fraction of the electron’s charge. Lightning generator. In 1929, American inventor Robert Van de Graaff created a device for generating large electrostatic fields from the friction of a rotating belt. The charge accumulates on the hollow metal sphere and can be discharged by bringing another metal object nearby.

July 9, 2026• Physics 19, 98 What can past bottlenecks and imagined technologies tell us about the future of AI? Imagined by artist Sébastien Garnier, the Kairos One facility combines linear and nonlinear quantum computing to perform calculations on a yottaflop (1024 floating-point operations per second) scale—a million times beyond today’s supercomputers.

A Widening Anomaly Strains the Standard Model July 8, 2026• Physics 19, 94 Does a new measurement of a rare decay of the neutral B meson portend new physics? Figure 1: The beam pipe of the LHCb experiment at CERN. The beam pipe’s main function is to sustain an ultrahigh vacuum for the colliding proton beams while enabling particles produced in the collisions to pass through its walls. Figure 1: The beam pipe of the LHCb experiment at CERN.

July 8, 2026• Physics 19, s79 New theoretical work indicates that an array of helium-3 atoms could enable more complex quantum simulations. Physicists orchestrate interactions between individual neutral atoms in arrays to simulate other quantum systems. However, the atoms can only encode information for as long as they retain their coherence, which limits the complexity of the simulations. Moving atoms faster to fit in more operations within the coherence time would circumvent that limitation.

July 7, 2026• Physics 19, 97 The exceptionally long sperm of fruit flies are able to fit in their small storage organ by swimming in opposite-direction lanes, new experiments show. This snapshot shows fluorescently labeled sperm swimming inside a male storage organ. The cells align with each other without forming knots. This snapshot shows fluorescently labeled sperm swimming inside a male storage organ. The cells align with each other without forming knots.

July 6, 2026• Physics 19, 99 A study of online language shows that niche terms—like the name of a narrowly popular music group—spread less quickly than mainstream words. Building followers. The Japanese musical group AKB48 grew in popularity on Japanese blogs, but their name spread slowly, being shared primarily within smaller subculture communities. Building followers.

July 1, 2026• Physics 19, s92 A technique combining spectroscopy and computational simulations allows the geometry and spin magnetic moment of iron nanoclusters to be determined more precisely. Nanoscale atomic clusters exhibit electronic properties unlike those of bulk materials made of the same atoms. Those properties depend sensitively on how the atoms are arranged, and they become hard to predict as the number of atoms rises beyond a handful.

June 30, 2026• Physics 19, 95 A long-awaited survey gets rolling, beginning a decade-long effort to produce the most expansive movie of the Universe ever recorded. Panning across the high-resolution “Ocean of Stars” image of the constellation Lupus, captured by the Rubin Observatory. Today, the NSF–DOE Vera C. Rubin Observatory kicks off its Legacy Survey of Space and Time (LSST), a ten-year effort to create a time-lapse record of the cosmos.
