Boosting the response speed of quantum LEDs via an excitation memory effect
Image of an emitting micro-QLED (approximately 60 microns in diameter) that demonstrates fast response capabilities. Credit: Lu et al. Light-emitting diodes (LEDs) are widely used electroluminescent devices that emit light…
Metasurfaces entangle light and information in new study
Polarization and holographic information become entangled in a quantum hologram. Holographic letters demonstrate entanglement through polarization of paired photons. By selecting different polarizer orientations for one photon, specific letters in…

Quantum entanglement sensors could test quantum gravity
Artist’s concept of SUPREME-GQ. Credit: S. Shahriar / NASA Ask almost any physicist what the most frustrating problem is in modern-day physics, and they will likely say the discrepancy between…
Metasurface technology offers a compact way to generate multiphoton entanglement
Generating multiphoton entanglement with a tiny metasurface. Credit: Peking University Quantum information processing is a field that relies on the entanglement of multiple photons to process vast amounts of information.…
Uncovering Einstein’s relativity in an interacting atomic playground
An optical lattice clock embedded in the curved spacetime formed by the earth’s gravity. Dynamical interplay between photon-mediated interactions and gravitational redshift can lead to entanglement generation and frequency synchronization…
