    "abstract": "We present an optical \"enantio-selective switch\", that, in two steps, turns a\n(\"racemic\") mixture of left-handed and right-handed chiral molecules into the\nenantiomerically pure state of interest. The optical switch is composed of an\n\"enantio-discriminator\" and an \"enantio-converter\" acting in tandem. The method\nis robust, insensitive to decay processes, and does not require molecular\npreorientation. We demonstrate the method on the purification of a racemate of\n(transiently chiral) D$_2$S$_2$ molecules, performed on the nanosecond\ntimescale.",
