Extremely Coherent Mechanical Oscillators and circuit Cavity Electro-Optics

The quest for mechanical oscillators with ultralow dissipation is motivated by classical and quantum sensing and technology, and precision measurements. For decades, the most coherent mechanical oscillators were acoustic vibrations in kg-scale crystalline bars. Recently a paradigm shift has occurred. The combination of elastic strain engineering – a technique used in microelectronics – with phononic mode engineering has resulted in 1D nano-strings with a mechanical quality factor Q of 0.8 billion – the highest ever achieved at room temperature. Remarkably, these new techniques have major untapped potential, as they have only been applied to non-crystalline materials in 1D. We propose a new…
