Abstract:
Due to their electrical charge-to-mass ratio, levitating electrons are ideal candidates for a medium to detect particles with very low momentum or energy, such as photons in the microwave and radiofrequency range. This fact can be utilized for the passive detection of devices emitting in those frequency bands or in quantum illumination protocols. However, this requires preparing the electrons in specific quantum states, which is the topic of this thesis. Specifically, it will address the cooling of electrons in interactions with laser-cooled ions. Within this work, we will further develop the latest model of a microwave trap capable of holding both ions and electrons. After successful operational tests, we will examine the interaction of the quantum ion-electron system following exposure to external electromagnetic radiation and work on defining a suitable detection protocol. These efforts will take place in conjunction with theoretical research at the Czech Academy of Sciences and the development of other parts of the experimental apparatus. The goal of the thesis is to synthesize all available knowledge and components into a functioning device.
