Oxford physicists reproduce the Aharonov-Bohm effect on a single loop of a simulated gauge theory
Oxford physicists reproduced the Aharonov-Bohm effect in a trapped-ion simulation of one gauge-theory loop built from two qubits and two oscillators. The simulated field was itself quantum and evolved with the matter, on a system far smaller than the lattices that strain classical computers.

Trapped-ion simulation finds gluon strings break first at the edges
Christopher Monroe's Duke team simulated gluon string breaking on trapped ions and got results similar to earlier neutral-atom and superconducting work. The team found the break starts at the edges, contrary to Schwinger's predictions.

Oxford physicists recreate the Aharonov-Bohm effect on a two-qubit trapped-ion loop
Oxford physicists used a hybrid trapped-ion quantum computer to stop a simulated particle tunneling with a magnetic flux it never crossed. Their setup is one loop of two qubits and two oscillators, a first building block for simulations that get harder for classical machines as they grow.

Universal Quantum, a University of Sussex spin-out, raised more than $100 million in a Series A co-led by DCVC and Firgun Ventures. The money goes into commercialising hardware at a company already delivering a $77 million contract for Germany's DLR, startup.eu reported.

Duke team uses 13 trapped ions to watch a simulated particle string break
Duke-led physicists used 13 trapped ions to reproduce string breaking, in which a stretched bond between particles snaps and new pairs form. Two other teams saw similar physics on other hardware, though at this size any payoff for particle physics is still a forecast.

A classical computer confirmed Duke's 13-ion simulation of string-breaking
String-breaking, the moment a stretched bond between two building blocks of matter snaps and new particles appear, has now been observed on a trapped-ion quantum simulator at Duke. Two other groups saw it on different hardware.

IonQ decodes 408 logical qubits in real time on twelve cores of an Apple M4 Max
IonQ researchers report a real-time error-correction decoder that added under 0.3% to runtime at a CNOT error rate of 10^-4, and under 12% at five times that rate, on workloads simulated against the company's own proposed architecture.

One trapped calcium ion shows a focused laser couples most strongly off the beam axis
A single trapped calcium ion has confirmed a years-old prediction that the strongest coupling point of a tightly focused laser sits off the beam axis, and the size of the displacement tracks wavelength alone.

A new IACR estimate sizes the secp256k1 break at 1,450 logical qubits and 40 million Toffoli gates
The algorithm-level numbers are the part of the estimate that can be recompiled onto any fault-tolerant machine, and the headline 25.7 days on 19,397 physical qubits belongs to the trapped-ion architecture its own authors proposed.

A trapped calcium ion finds peak laser coupling 463 nanometers off the beam's center
ETH Zurich scanned a tightly focused 729-nanometer beam across a nearly motionless ion and found the coupling peak sitting hundreds of nanometers to the side, by an amount that changes with the transition being driven.
