Quantum entanglement could link distant telescopes for sharper images

Astronomers propose using quantum entanglement to link distant telescopes, potentially revolutionizing long-baseline interferometry for sharper cosmic images by 2026. This method could surpass classical limits by leveraging quantum correlations between photons. Current interferometry combines light from separate telescopes to simulate a larger aperture, but distance and noise limit resolution. Quantum entanglement may eliminate these barriers by synchronizing telescopes with unprecedented precision. Researchers suggest entangled photon pairs could encode celestial light signals, enabling error-free data fusion across continents or even space-based observatories. This would unlock finer details of black holes and exoplanets. The technique builds on recent quantum networking advances, including satellite-based entanglement distribution. Early lab tests show promise, though scaling remains a challenge for real-world astronomical applications. If successful, this approach could redefine observational astronomy, offering resolutions rivaling theoretical maximums—without building physically larger telescopes. Peer-reviewed trials are expected within the decade.
