Ground-Moving Target Indication Using Along-Track SAR Interferometer Designed With Triangular Frequency-Modulated Continuous Wave Radar

Abstract: Synthetic aperture radar-ground-moving target indication (SAR-GMTI) system generates 2-D images of the observed area and detects moving targets within the image. Along-track SAR ...

Neutral-atom arrays, a rapidly emerging quantum computing platform, get a boost from researchers

For quantum computers to outperform their classical counterparts, they need more quantum bits, or qubits. State-of-the-art ...

Quantum-dot device can generate multiple frequency-entangled photons

Researchers have designed a new device that can efficiently create multiple frequency-entangled photons, a feat that cannot be achieved with today's optical devices. The new approach could open a path ...
