STEP TOWARD QUANTUM COMPUTING, SPINTRONIC MEMORY, BETTER
DISPLAYS
University of Utah physicists read the subatomic “spins” in
the centers or nuclei of hydrogen isotopes, and used the data to control
current that powered light in a cheap, plastic LED – at room temperature and
without strong magnetic fields.
The study – published in Friday’s issue of the journal
Science – brings physics a step closer to practical machines that work
“spintronically” as well as electronically: superfast quantum computers, more
compact data storage devices and plastic or organic light-emitting diodes, or
OLEDs, more efficient than those used today in display screens for cell phones,
computers and televisions.
