Controlling electron interference in time with chirped laser pulses
Illustration of chirped laser-assisted dynamic interference. Credit: Federico Vismarra, ETH Zürich In quantum mechanics, particles such as electrons act like waves and can even interfere with themselves—a striking and counterintuitive…
Quantum scars boost electron transport and drive the development of microchips
The image depicts a quantum scar connected between conductors. It can be controlled using a so-called nanotip carrying an electric charge. Credit: Quantum Control and Dynamics research group, Tampere University…
‘Quantum squeezing’ a nanoscale particle for the first time
(Upper panel) Experimental time sequence to realize and observe quantum squeezing of a levitated nanoparticle. After cooling the center-of-mass motions, the researchers vary the laser intensity to deform the uncertainties…
