Phase estimation in lossy optical interferometry without a reference beam
We investigate phase estimation in a lossy interferometer using entangled coherent states, with particular focus on a scenario where no reference beam is employed. By calculating the quantum Fisher information, we reveal two key results: (1) the metrological equivalence between scenarios with and without a reference beam, established under ideal lossless conditions for the two-phase-shifting configuration,breaks down in the presence of photon loss, and (2) the pronounced inferior performance of…

Good to see the other states have come on board with police officer decertification policies. Rhode Island needs to get with the program.

Rhode Island resists efforts at policing reform embraced by every other state
In October, a Newport County jury found that former Jamestown Police Det. Derek Carlino was negligent in his involvement in the death by suicide of a teenager. But it won’t end Carlino’s career in policing. A report commissioned by the Portsmouth School Department found Carlino had worked with a football coach to pressure fifteen-year-old Nathan […]

Digital twins enable full-reference quality assessment of photoacoustic image reconstructions
Quantitative comparison of the quality of photoacoustic image reconstruction algorithms remains a major challenge. No-reference image quality measures are often inadequate, but full-reference measures require access to an ideal reference image. While the ground truth is known in simulations, it is unknown in vivo, or in phantom studies, as the reference depends on both the phantom properties and the imaging system. We tackle this problem by using numerical digital twins of tissue-mimicking phan…

Optical frequency division referenced to microhertz-linewidth quantum-noise-limited lasers
Optical frequency division (OFD) implements the conversion of ultra-stable optical frequencies into microwave frequencies through an optical frequency comb flywheel, generating microwave oscillators with record-low phase noise and time jitter. However, conventional OFD systems face significant trade-off between division complexity and noise suppression due to severe thermal noise and technical noise in the optical frequency references. Here, we address this challenge by generating common-cavity…
