A team at the University of Kansas will develop intelligent spectrum management frameworks to enable reliable communication for drones. They aim to study how to use a proposed 5030-5091 MHz frequency band efficiently, with potential benefits including quicker deliveries and improved emergency response.
Researchers developed a low-power, high-frequency signal transmission tag that can efficiently reflect signals at untapped frequencies, eliminating the need for power-hungry signal transmitters. This technology enables real-time monitoring in industrial settings and has potential applications in smart cities and agriculture.
A team of international researchers successfully controlled the quantum states of matter at ultrafast time scales and its chemical properties with extreme precision using light in the extreme ultraviolet. The technique was demonstrated on helium atoms, enabling the enhancement of selected quantum processes while suppressing others.
A recent breakthrough in ultra-broadband diffractive imaging has enabled the handling of unknown probe spectra, overcoming constraints on non-dispersive specimens. This innovation provides a nearly fourfold improvement in bandwidth over current mono CDI methods.
A team of researchers has demonstrated a novel way of storing and releasing X-ray pulses at the single photon level, enabling future X-ray quantum technologies. This breakthrough uses nuclear ensembles to create long-lived quantum memories with improved coherence times.
Researchers have developed Coherent Two-Photon LIDAR, eliminating range limitations imposed by coherence time. This technique uses phase-dependent interference to measure distances beyond the coherence time of the light source.
Researchers have developed a novel air-laser-based standoff Raman spectrometer with high temporal and frequency resolutions. The device enables remote detection of chemical species in real time, monitoring their rovibronic levels and populations in the frequency domain.
