Quantum communication (QC) systems harness modern physics through state-of-the-art optical engineering to provide revolutionary capabilities. An important concern for QC engineering is designing and prototyping these systems to evaluate the proposed capabilities. We apply the paradigm of software-defined communication for engineering QC systems to facilitate rapid prototyping and prototype comp...

We propose a new method for generating programmable interactions in one- and two-dimensional trapped-ion quantum simulators. Here we consider the use of optical tweezers to engineer sound-wave spectrum trapped ion crystals. show that this approach allows us tune connectivity qubits beyond power-law accessible current setups. demonstrate experimental feasibility our proposal using realistic twee...

The capacity of optical communication channels can be increased by space division multiplexing in structured fibers. Radial core fibers allows for the propagation twisted light–eigenmodes orbital angular momentum, which have attracted considerable attention high-dimensional quantum information. Here we study generation entangled photons that are tailor-made coupling into ring We show photon pai...

Titanium dioxide (TiO2) nanoparticles were modified onto fluorine-doped tin oxide (FTO) via dip-coating technique with different nanoparticle sizes, lifting speeds, precursor concentrations, and dipping numbers. Electrodeposition-based electrochromic device with reversible three-state optical transformation (transparent, mirror, and black) was fabricated subsequently by sandwiching a suitable a...

The interaction between light and acoustic phonons is strongly modified in sub-wavelength confinement, and has led to the demonstration and control of Brillouin scattering in photonic structures such as nano-scale optical waveguides and cavities. Besides the small optical mode volume, two physical mechanisms come into play simultaneously: a volume effect caused by the strain-induced refractive ...
