“Exotic Kind of Magnetic Behavior” Could Be a Building Block for Future Quantum Computers

  • MIT researchers have taken a new look at an “exotic kind of magnetic behavior” using a technique called spin-polarized neutron reflectometry.
  • The behavior happens when a ferromagnet meets a topological insulator, which prevents electricity from passing through but is actually a good conductor on its surface. When the materials were bonded by researchers, a localized and controllable magnetic pattern was observed at the interface.
  • This is an early stage discovery, but scientists believe the finding could lead to future quantum computers as well as being valuable for physicists as a tool for study.
