Now scientists at the University of Manchester have proved that storing data with a class of molecules known as single-molecule magnets is more feasible than previously thought.  The new work shows that collections of ultracold molecules can retain the information stored in them, for hundreds of times longer than researchers have previously achieved in these materials.  Quantum entanglement can improve the sensitivity of a measurement, as has been demonstrated previously for atomic clocks and magnetic-field sensors.  Thanks to a new fabrication technique, quantum sensing abilities are now approaching this scale of precision.  For decades scientists have known that a quantum computer—a device that stores and manipulates information in quantum objects such as atoms or photons—could theoretically perform certain calculations far faster than today's computing schemes.  Magnets and magnetic phenomena underpin the vast majority of modern data storage, and the measurement scales for research focused on magnetic behaviors continue to shrink with the rest of digital technology.  Scientists have recently created a new spintronics material called bismuthene, which has similar properties to that of graphene.  The expanding field of spintronics promises a new generation of devices by taking advantage of the spin degree of freedom of the electron in addition to its charge to create new functionalities not possible with conventional electronics.  An international team of researchers, working at the fabricated an atomically thin material and measured its exotic and durable properties that make it a promising candidate for a budding branch of electronics known as "spintronics."  The emerging field of spintronics aims to exploit the spin of the electron.  In a new study, researchers measure the spin properties of electronic states produced in singlet fission – a process which could have a central role in the future development of solar cells.
