Demonstration of wideband RF electric field sensing in a trapped ion via motional Raman transitions, achieving 3.4 dB below the standard quantum limit over a frequency range more than 800 times larger than prior QHO methods.
Reports experimental measurement of RF signal frequency at 7e-9 fractional uncertainty using subharmonic excitation in a single Ca ion quantum harmonic oscillator, claimed as most precise with this platform.
Non-Markovian local dissipative environments protect spin squeezing, enabling robust steady-state squeezing beyond the Born-Markov approximation.
Proves equalities among quantum Wasserstein distances obtained from optimizations over general versus separable bipartite states and shows relations to Uhlmann-Jozsa fidelity and superfidelity, including equality for qubits.
Extends qubit-channel metrology to spectator noise, supplying algebraic tests that decide when correlated n-qubit inputs beat single-qubit inputs under different noise types.
Design proposal for an entanglement-enhanced BEC atomic sensor targeting microgravity experiments in the Einstein-Elevator, addressing SWaP and noise constraints for future space use.
