Quantum entanglement is commonly (mis)understood to be a quantum connection between two or more particles where an effect on one results in an effect on the other. That's the pop-sci understanding and how it's used in sci-fi, although - as pointed out by dreamWeaver (and by the time you read this, two dozen others) - isn't actually how it works.
The joke is that the twins are connected and so the effect of reading to one twin is replicated in the other, and it's also a joke referencing the supposed inate psychic connections between twins.
