A scalable numerical framework simulates laser cooling of large 3D ion crystals in Penning traps, identifying axial mode additions and prolate geometries that achieve sub-1 mK perpendicular temperatures with simplified beam setups.
Squeezing phase noise in a trapped-ion Duffing oscillator induces stochastic resonance that amplifies weak electric-field signals and raises SNR by 4.28 dB over conventional noise-driven SR.
Sequential weak measurements on a quantum harmonic oscillator enable simultaneous quadrature estimation, with backaction increasing information for some strengths and post-processing extending dynamic range while improving decoherence robustness.
For suitable spatial and temporal correlations in non-Markovian dephasing, entangled probes achieve superior sensitivity scaling with probe number compared to separable states in Ramsey spectroscopy.
Phase-locked phonon laser in levitated nanoparticles reduces force noise to 4.0(3)×10^{-22} N/√Hz, achieves 12,500 s coherence, and delivers 8(4)×10^{-24} N resolution.
