Scientists know that entanglement, a special connection that intertwines the fate of quantum particles, is a crucial ingredient for quantum computers. Without it, a quantum computer loses its ability to harness the fullness of quantum complexity—that special sauce that makes the quantum world impossible to emulate on ordinary computers. But whether entanglement is the only key, and exactly how much of it is needed, no one really knows. 

When Hurricane Ian struck southwest Florida in September 2022, it unleashed a variety of Vibrio bacteria that can cause illness and death in humans, according to a new study published in the journal mBio.

If gamblers, investors and quantum experimentalists could bend the arrow of time, their advantage would be significantly higher, leading to significantly better outcomes. Working with collaborators at the University of Cambridge, Nicole Yunger Halpern(link is external), a Fellow in the Joint Center for Quantum Information and Computer Science (QuICS), has shown that by manipulating entanglement, researchers can simulate what could happen if one could travel backwards in time.
