The companies report a component-level measurement of 7 mdB, about a third of the roughly 20 mdB published in 2025. In photonic quantum computers, photon loss accumulates across switches.
A prototype at TU Wien locks a laser to thorium nuclei without a conventional atomic clock. Its precision is about 10^-15, still below the best optical atomic clocks.
A Delft University of Technology team flipped the nuclear spin of a single atom even when it was largely disentangled from the electron spin, contrary to the authors' expectations.
Photon pairs from two independent gallium arsenide quantum dots were used for entanglement swapping in a laboratory setup, a step toward quantum repeaters. Fidelity reached 0.71 with time selection.
A prototype three-qubit superconducting processor performs CCZ in one pulse instead of the usual eight two-qubit operations, which reduces accumulated error.
A prototype speckle spectrometer built around an integrating sphere resolves 6 fm at 780 nm, about 80 times finer than earlier speckle devices, and measured rubidium hyperfine structure.
ML-DSA and SLH-DSA are final, FN-DSA has no public draft, and on May 14, 2026 NIST named nine candidates for a third round of additional signatures.
A 1-bit feedback protocol on an FPGA controller compensated TLS-induced frequency jumps of a superconducting qubit, lowering average single-gate error from 0.14% to 0.065%.
Floquet-engineered interference between two Feshbach resonances decoupled a molecular state from the continuum in ultracold lithium-6 collisions, the authors report.
Researchers at the University of Osaka ran a four-hydrogen-atom quantum chemistry test as a single workflow across a supercomputer and a superconducting quantum computer. It is a first in Japan.
Researchers at Ames National Laboratory report that magnon bands of opposite handedness cross in RMn6Sn6 ferrimagnets and can be gapped by changing the magnetic order or applying a field.
Laser pulses drove a magnetic material out of equilibrium, and neutron scattering at the Spallation Neutron Source showed detailed balance broken and the state persisting.
On China's space station, researchers tracked a rubidium cloud for seven seconds in microgravity and derived a temperature equivalent of 9.7 picokelvin, a quarter of the prior record.
Researchers from nanoGUNE, Quantum Motion and partner universities made a nonlinear superinductor in a silicon circuit with commercial CMOS fabrication, as reported in Nature Electronics.
Leiden physicists distinguished one, two and three or more photons in recorded signals of a superconducting nanowire detector, a step toward optical quantum computers.
A preprint by Alice & Bob and a Rennes researcher gives a theoretical estimate for factoring RSA-2048. No machine of this size exists, and the paper is not peer reviewed.
In an optical lattice, a team resolved three fermion components atom by atom, observed a Mott state and competing magnetic correlations, and compared the data with numerical calculations.
A theoretical study shows how a three-junction node in a magnetic field can create, move and fuse Majorana states, steps needed for braiding in topological qubits.
A laser experiment with a metal tip resolved electron tunneling on attosecond scales and showed that finer timing stretches the electron wave packet in space.
An international team created a supersolid state of a quantum fluid of light at room temperature in a microcavity with liquid crystal, with no cryogenic cooling needed.
