The entanglement of quantum objects can take surprising forms. Quantum physicists at the University of Innsbruck have investigated several flavors of entanglement in four trapped ions and report their results in the journal Nature Physics. Their study promotes further developments towards quantum computing and a deeper understanding of the foundations of quantum mechanics.<!--eec6d63ab9254743b4cb276771aa8eaa-->
