In the second part I present experimentally accessible conditions for detecting entanglement<br \/>\nin mixed states. These conditions are based on the moments of the partial transposed density operator, which can be measured via local random measurements on single state copies (classical shadows).<\/p>\n<p>Ref:<\/p>\n<p>J.
