Silicon anisotropy in a bi-dimensional optomechanical cavity

In this work, we study the effects of mechanical anisotropy in a 2D optomechanical crystal geometry. We fabricate and measure devices with different orientations, showing the dependence of the mechanical spectrum and the optomechanical coupling on the relative angle of the device to the crystallography directions of silicon. Our results show...

Towards an Optomechanical Quantum Memory: Preparation and Storage of Non-Classical States in High-Frequency Mechanical Resonators

Cavity Optomechanics is a field employing optical control over mechanical oscillators with a variety of possible applications for sensing, optical signal processing as well as quantum technologies. Such systems are attractive because they are often fully engineerable and can be tailored to specific applications by allowing a large range of...

Proposal for optomechanical quantum teleportation

We present a discrete-variable quantum teleportation scheme using pulsed optomechanics. In our proposal, we demonstrate how an unknown optical input state can be transferred onto the joint state of a pair of mechanical oscillators, without physically interacting with one another. We further analyze how experimental imperfections will affect...

Platform for Measurements of the Casimir Force between Two Superconductors

Several experimental demonstrations of the Casimir force between two closely spaced bodies have been realized over the past two decades. Extending the theory to incorporate the behavior of the force between two superconducting films close to their transition temperature has resulted in competing predictions. To date, no experiment exists that...

Optomechanical Bell Test

Over the past few decades, experimental tests of Bell-type inequalities have been at the forefront of understanding quantum mechanics and its implications. These strong bounds on specific measurements on a physical system originate from some of the most fundamental concepts of classical physics - in particular that properties of an object are...
