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…
Single device amplifies signals while shielding qubits from unwanted noise
Optical micrograph of the traveling-wave parametric amplifier and converter chip. The periodic square structures along the central transmission line are Josephson junctions, while the larger rectangular structures are the capacitors…
Machine learning unravels quantum atomic vibrations in materials
Credit: Rosa Romano, EAS Communications/Caltech Caltech scientists have developed an artificial intelligence (AI)–based method that dramatically speeds up calculations of the quantum interactions that take place in materials. In new…
Seeing a trio of entangled photons in one go
Achieving the entanglement measurement of the W state. Credit: KyotoU / Takeuchi lab The concept of quantum entanglement is emblematic of the gap between classical and quantum physics. Referring to…
New quantum sensors can withstand extreme pressure
A schematic image shows a 2D sensor squeezed between two diamond anvils. Credit: Chong Zu The world of quantum physics is already mysterious, but what happens when that strange realm…
