Four experimental plots show how potassium-41 and cesium transfer efficiencies change with gray-molasses duration and optical intensity.

Potassium-41 and Cesium Reached 10 Microkelvin, Opening a New Route Toward Polar Molecules

A Warsaw team trapped more than a million atoms of each species and mapped 14 resonances in a related isotope mixture. Rapid potassium-41 losses still block the spectroscopy needed for molecule assembly.

A scientific workflow diagram connects a matrix-product-state calculation and shallow-circuit compilation to selected qubits on an IBM processor, followed by string-order and entanglement-spectrum measurements.

IBM Hardware Measured 20-Site String Order in a 100-Qubit Spin Chain

Shallow compiled circuits exposed three signatures of topological order, but their 97.9 to 99.0 percent overlaps were classical calculations, not hardware-state fidelities.
