Electron Timing Limit Could Enable Far Faster Electronics

Buzzline

Physicists at the University of Regensburg and the Max Planck Institute in Hamburg experimentally demonstrated a new “space-time limit”: an electron’s location and timing cannot both be pinned down with unlimited precision, ScienceDaily reports. With a new laser system and an ultrafast microscope, the team filmed electrons tunneling across a gap of a few atoms in attoseconds. Their motion lagged the laser by about 500 attoseconds. The researchers say understanding this trade-off could open the door to quantum electronics far faster than today’s devices.

00:00Physicists just filmed electrons moving faster than almost anything ever measured,

00:04and they found a new rule of nature along the way.

00:07The team works at the University of Regensburg and the Max Planck Institute in Hamburg.

00:12They built a laser system paired with an ultra-fast microscope.

00:15Laser pulses pushed electrons from a sharp metal tip toward a silver surface.

00:20The gap was just a few atoms wide.

00:22The electrons crossed it by quantum tunneling,

00:25slipping through a barrier like a ghost through a wall.

00:28It all happened in attoseconds, billionths of a billionth of a second.

00:32The electrons lagged the laser by about 500 attoseconds.

00:36Then came the big finding, a space-time limit.

00:39The more precisely they timed an electron, the more it spread out in space.

00:44Understanding that trade-off could help engineers design much faster quantum electronics.

00:49Future chips may run on attosecond timescales.

00:52Disclosure.
