Watch: Media Lab Professor Deblina Sarkar explains "spintronics," which broadly refers to the use of magnetic materials and the "spin" of electrons to perform computation. This technology offers a path to making computers much more energy efficient, a vital need as computation demands related to big data, artificial intelligence, and the Internet of Things (IoT) increase worldwide.
