Photons, the quanta of light, possess several different degrees of freedom, e.g., frequency, polarisation, spatial and temporal modes, which can be used as platforms for quantum information applications. Polarisation, corresponding to the vectorial nature of light, is bi-dimensional and can represent ‘0’ and ‘1’ in the digital world. Unlike, polarisation, transverse and temporal modes would...
Here I discuss the possibilities to use nanomechanical resonators to converter information between microwave and optical domains. Additionally, I demonstrate an on-chip magnetic-free circulator based on reservoir-engineered electromechanical interactions. Directional circulation is achieved with controlled phase-sensitive interference of six distinct electromechanical signal conversion paths....
Despite incredible experimental progress in quantum optomechanics, the intrinsically weak coupling between light and motion remains a bottleneck for accessing the full potential of these systems. While a strong pump field can parametrically enhance the optomechanical coupling, it also acts to obscure the fundamental nonlinearity of the interaction and hinders integration with single photon...
Optical quantum memory that has the ability to store and on-demand, recall the quantum states of light with high efficiency and fidelity which has several applications in linear-optical quantum computation, single-photon detection, quantum metrology, tests of the foundations of quantum physics is one of the essential elements in distribution of quantum entanglement for long distance quantum...
Thin film deposition on substrates inclined with respect to the flux of evaporated materials can be used to produce anisotropic porous nanostructures displaying effective anisotropic optical properties at the wavelength scale. When the orientation of the substrate is changed during the deposition process, sculptured thin films are grown, whose optical properties can be continuously controlled...
Trapped ions for quantum information processing has been an area of intense study in the past twenty years due to the extraordinarily high-fidelity operations that have been achieved experimentally, and the recent microfabricated traps that offer a potential path to scaling the technology. Specifically, the Barium-133 trapped ion has been shown to have some of the highest fidelity operations...
A programmable quantum simulator can simulate models of quantum many-body systems that may otherwise be impossible to be modeled with conventional computers. Simulation of such many-body quantum systems may further advance our understanding of exotic quantum materials, fundamental forces of nature, molecules for drug discovery, etc. Laser-cooled and trapped atomic ions serve as an ideal...
