Nonpolar atoms or molecules with low particle mass and weak inter-particle interactions can
form quantum liquids and solids (QLS) at low temperatures. Excess electrons naturally bind …

The image-charge detection provides a new direct method for the detection of the Rydberg
transition of electrons trapped on the surface of liquid helium. The interest in this method is …

Sensitive detection of electromagnetic wave electric field plays an important role for
electromagnetic communication and sensing. Here, we propose a quantum sensor to …

We report on low-frequency measurements of few electrons floating on superfluid helium
using a bespoke cryogenic cascode amplifier circuit built with off-the-shelf GaAs high …

We propose a frequency-mixed effect of terahertz (THz) and gigahertz (GHz)
electromagnetic waves in the cryogenic system of electrons floating on liquid helium surface …

Over the past decade, numerous reputable companies, including IBM, Google, Microsoft,
and various startups, have invested substantial resources in industrial research on quantum …

The theoretical study [Phys. Rev. A, 2006, 74: 052338] shows that electron spin on liquid
helium surface has a coherence time of up to 100 seconds, and thus could be used for …
