Web2 days ago · In the age of information explosion, the conventional optical communication protocols are rapidly reaching the limits of their capacity, as almost all available degrees of freedom (e.g., wavelength, polarization) for division multiplexing have been explored to date. Recent advances in coherent mode division multiplexing have greatly facilitated high … WebCoherent plane-wave compounding (CPWC) enables high-frame-rate ultrasound imaging, but the imaging quality is mainly determined by the beamforming method. Covariance-matrix-based statistical beamforming (CMSB) was previously proposed for synthetic aperture ultrasound imaging, which provides notable improvements in resolution and contrast over …

WebIf the plane waves or momentum eigenstates have a well-defined phase relationship, the atomic ensemble may be described by a wave packet. A continuous beam experiment cannot distinguish between a coherent superposition of plane waves (wave packet) and an incoherent superposition as in Eq. (10). Therefore, we are free to choose whether we use ... WebThe waves are then entangled with the particle because of momentum conservation (leaving the final particle having momenta k f, k f ′, … respectively). When only the emitted waves are observed, this entanglement can lead to quantum decoherence and lack of interference visibility, resulting in the emission of incoherent radiation.
