The superposition principle is the cornerstone of quantum mechanics, leading to a variety of
genuinely quantum effects. Whether the principle applies also to macroscopic systems or …

Optomechanics is concerned with the use of light to control mechanical objects. As a field, it
has been hugely successful in the production of precise and novel sensors, the …

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 …

Photonic integrated circuits (PICs) based on lithographically patterned waveguides provide
a scalable approach for manipulating photonic bits, enabling seminal demonstrations of a …

We discuss effects of loss of coherence in low energy quantum systems caused by or related
to gravitation, referred to as gravitational decoherence. These effects, resulting from random …

Cavity optomechanical systems have been shown to exhibit an analogon to atomic
electromagnetically induced transparency that a transmission window for the propagation of …

Large-scale quantum effects have always played an important role in the foundations of
quantum theory. With recent experimental progress and the aspiration for quantum …

Cavity electromechanics relies on parametric coupling between microwave and mechanical
modes to manipulate the mechanical quantum state, and provide a coherent interface …

We consider two interacting systems when one is treated classically while the other system
remains quantum. Consistent dynamics of this coupling has been shown to exist, and …

Quantum technologies are opening novel avenues for applied and fundamental science at
an impressive pace. In this perspective article, we focus on the promises coming from the …
