Highlights from our latest papers and preprints.
We inject electron wavepackets as short as 4 ps into a quasi-one-dimensional electron waveguide, 10 to 40 µm long, and actively control their propagation speed. This is a building block for ultrafast quantum operations with flying electrons.
Using a cavity, we isolate and select the electron conduction channels that contribute to a plasmon wavepacket, which gives precise control of its eigenstate and so of its propagation speed.
We inject ultrashort single-electron plasmonic pulses into a 14-micrometre-long electronic Mach-Zehnder interferometer, a step towards flying electron qubits operated on picosecond time scales.
