The quantum nature of an oscillating mechanical object is anything but apparent. The
coherent states that describe the classical motion of a mechanical oscillator do not have a …

In optics, the ability to measure individual quanta of light (photons) enables a great many
applications, ranging from dynamic imaging within living organisms to secure quantum …

Precisely engineered mechanical oscillators keep time, filter signals and sense motion,
making them an indispensable part of the technological landscape of today. These unique …

Achieving coherent quantum control over massive mechanical resonators is a current
research goal. Nano-and micromechanical devices can be coupled to a variety of systems …

Cold, macroscopic mechanical systems are expected to behave contrary to our usual
classical understanding of reality; the most striking and counterintuitive predictions involve …

Heisenberg's uncertainty principle results in one of the strangest quantum behaviours: a
mechanical oscillator can never truly be at rest. Even at a temperature of absolute zero, its …

The energy damping time in a mechanical resonator is critical to many precision metrology
applications, such as timekeeping and force measurements. We present measurements of …

Quantum information can be stored in micromechanical resonators, encoded as quanta of
vibration known as phonons. The vibrational motion is then restricted to the stationary …

Mechanical objects have important practical applications in the fields of quantum information
and metrology as quantum memories or transducers for measuring and connecting different …

The observation of the quantum states of motion of a macroscopic mechanical structure
remains an open challenge in quantum-state preparation and measurement. One approach …
