Demonstrating entanglement in extreme ultraviolet light is a useful step for quantum optics, since it shows the entanglement certification can work at frequencies where earlier methods needed extra optical hardware. The method's practical value depends on whether attosecond photoelectron measurements can reliably reproduce these witnesses outside controlled experiments. For readers, the main takeaway is a new verification tool, not a near-term application.
Researchers Certify Entangled Light with Electron Interference

Entangling light at extreme ultraviolet wavelengths has outpaced our ability to prove it actually works, until now. Attosecond photoelectron interferometry offers experimentally accessible tests confirming quantum links in these fields, bypassing complex optics needed by previous methods. This establishes a versatile new approach to certifying entangled light regardless of frequency, opening avenues in strong-field quantum optics.
Attosecond photoelectron interferometry offers an experimentally accessible method to certify entanglement in extreme ultraviolet radiation. Linking measurements of electron signals from multiple sidebands, central, upper and lower, to optical correlation functions provides witnesses for infrared-XUV entanglement and genuine multipartite entanglement without needing additional optical instruments. It is a flexible framework applicable across various frequencies for verifying quantum light properties. A new technique confirms entanglement, a key quantum property, within extreme ultraviolet radiation. The…
