Experimental observations reveal self-healing in single-photon wave packets, suggesting potential in quantum communication.
We demonstrate experimentally the self-healing of spatiotemporally structured single-photon wave packets. After traversing an opaque obstruction, the single-photon spatial profile (from an entangled-photon pair) is rapidly reconstituted, which may be useful for resilient quantum communication.
