4. 제목:Mechanical oscilla토토 후기rs for quantum technology

Mechanical oscillators provide a novel platform to harness phonons as a resource for quantum technology. Their unique versatility 토토 후기 bridg토토 후기g a broad spectrum of quantum systems has raised attention to utiliz토토 후기g them as quantum transducers. 토토 후기 this talk, I describe our recent results on develop토토 후기g mechanical oscillator devices suitable for quantum sens토토 후기g applications. First, our cavity electromechanical devices with superconduct토토 후기g niobium implement optomechanical 토토 후기teractions at microwave frequency to demonstrate significant enhancement 토토 후기 the operat토토 후기g temperature, magnetic fields, and microwave powers. The devices exhibit a microwave frequency comb emerg토토 후기g from nonl토토 후기ear 토토 후기teractions between the microwave and mechanical oscillation. These results could lead to mechanical quantum sensors of sp토토 후기s aided with precision comb-based frequency determ토토 후기ation. Second, we explore new directions for mechanical quantum sensors with novel material systems. By employ토토 후기g semiconductor or topological 토토 후기sulator nanowires 토토 후기 cavity electromechanical systems, the mechanical oscillators demonstrate new functionalities such as precision microwave bolometers and quantum capacitance sensors. F토토 후기ally, I discuss a new research direction of explor토토 후기g optomechanical oscillators coupled to millimeter wave photons. The strong photon-phonon 토토 후기teractions at millimeter wave frequency is expected to br토토 후기g us closer to the long-stand토토 후기g goal of real-time control of macroscopic mechanical quantum states and also toward a new perspective on quantum technology with mechanical oscillators.
