Scientists have shown for the first time that entanglement, the mysterious link between quantum particles, can be reversibly manipulated just like heat or energy in a perfect thermodynamic cycle.
For more than a century, the laws of thermodynamics have helped us understand how energy moves, how engines work, and why time seems to flow in one direction. Now, researchers have made a similarly powerful discovery, but in the strange world of quantum physics.The researchers support their findings using a novel concept called an entanglement battery, which allows entanglement to flow in and out of quantum systems without being lost, much like a regular battery stores and supplies energy.
It can give or take entanglement during transformations, so long as the total amount stored in the battery isn’t reduced.By carefully accounting for the flow of entanglement into and out of the battery, the researchers showed that even the most complicated entangled states could be converted into other states and then brought back without any loss.Their results apply in the asymptotic limit, meaning when large numbers of identical entangled states are used.
