Ultrafast Laser Creates Spin-Entangled Electrons

Facebook X LinkedIn Email
A research team at the University of Michigan in Ann Arbor and the University of Notre Dame in Indiana has reported the entanglement of three electrons in a CdTe quantum well using ultrafast laser pulses. The work, which was published in the March issue of Nature Materials, promises to enable the entanglement of larger numbers of particles for use in the development of a quantum computer. To produce entangled electrons, the scientists generated localized excitons in the quantum well with 130-fs pulses from a mode-locked Ti:sapphire laser by tuning the laser to resonate with a gap 80 meV...Read full article
