Derives differential upper bounds on quantum Fisher information for time-dependent metrology under Markovian noise and proves universal long-time scaling laws saturated by quantum error correction.
A polylog-sized quantum computer achieves exponential advantage over classical machines in classification and dimension reduction of massive classical data using quantum oracle sketching combined with classical shadows.
VISTA achieves near-Heisenberg scaling in moderately noisy quantum magnetometry by passively evolving a probe, comparing it via swap test to a physics-informed quantum twin circuit, and optimizing only physical parameters with quasi-normalization.
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.
An Al+ single-ion clock is evaluated at 1.6×10^{-18} systematic uncertainty with absolute frequency 1121015393207859.19(24) Hz and ratio to Sr clock of 2.611701431781462668(36).
A full-stack quantum receiver with qubit ensembles is proposed that achieves channel capacity beyond the SIC limit in low-SNR multiple access channels via quantum correlated measurements.
Fast quantum-battery charging and generation of metrologically useful entanglement are shown to arise from the same dynamics, with a proposed dual-use superconducting protocol.
