Description
The nature of quantum states of light is inherently governed by the
Heisenberg uncertainty principle, leading to the presence of zero-point
energy. A squeezed vacuum state emerges as a reshaped fluctuation of
this zero-point energy. To characterize and comprehend a squeezed
vacuum, the utilization of a bright field becomes pivotal. This bright
field not only amplifies the squeezed vacuum but also elevates it above
the classical photodetectors' detection threshold. Transforming the
detected electrical signals of the squeezed vacuum into sound via
speakers provides an additional auditory dimension to grasp the
intricacies of this quantum concept.
In this presentation, I will introduce a device designed for generating
a squeezed vacuum. A simple and cost-effective headphone has been
ingeniously modified to convert electrical signals into sound, enabling
us to explore various points in the squeezed vacuum generation system.
Throughout the talk, we will experience the steady sound of a squeezed
vacuum state. By systematically scanning the phase difference between
the squeezed vacuum and the bright field, we can discern the intricate
structure of the squeezed vacuum.
This exploration into sonification not only enhances our understanding
of quantum dynamics but also demonstrates a practical and accessible
approach to studying squeezed vacuum states.
