Approaching the double-Heisenberg scaling sensitivity in the Tavis–Cummings model

APL Photonics
The pursuit of quantum-enhanced parameter estimations without the need for nonclassical initial states has long been driven by the goal of achieving experimentally accessible quantum metrology.

Precision Test of Bound-State QED at Intermediate-Z with Kaonic Neon

We report Dirac-Fock calculations of transition energies for kaonic neon (KNe). For the most intense line, the 7-6 transition, the calculated energy is 9450.28 eV, which includes a bound-state QED (BSQED) contribution of 12.66 eV. This is in excellent agreement with the recent SIDDHARTHA-2 measurement at DA$Φ$NE of 9450.23 $\pm$ 0.37 (stat.) $\pm$ 1.50

$\alpha_{QED, eff}$(s) for precision physics at the FCC-ee/ILC

, 2019
Discovering “Physics behind precision” at future linear or circular colliders (ILC/FCC projects) requires improved SM predictions based on more precise input parameters. I will review the role αQED, eff at future collider energies and report on possible progress based on results from low energy machines.
