          Abstract

          The estimations done confirm a feasibility of the idea that gold nanobars (GNBs) and nanorings (GNRs) irradiated by microwaves could become the terahertz (THz) emitters with photon energies within the full width at half maximum of longitudinal acoustic phononic DOS of gold (~13.7-17.5 meV, i.e., 3.3-4.2 THz). A scheme of the THz radiation source is suggested based on the domestic microwave oven irradiating a substrate with multiple deposited GNBs or GNRs.

              Non-classical correlations between single photons and phonons from a mechanical oscillator

              , , (2016)
              Interfacing a single photon with another quantum system is a key capability in modern quantum information science. It allows quantum states of matter, such as spin states of atoms, atomic ensembles or solids, to be prepared and manipulated by photon counting and, in particular, to be distributed over long distances. Such light-matter interfaces have become crucial to fundamental tests of quantum physics and realizations of quantum networks. Here we report non-classical correlations between single photons and phonons -- the quanta of mechanical motion -- from a nanomechanical resonator. We implement a full quantum protocol involving initialization of the resonator in its quantum ground state of motion and subsequent generation and read-out of correlated photonphonon pairs. The observed violation of a Cauchy-Schwarz inequality is clear evidence for the non-classical nature of the mechanical state generated. Our results demonstrate the availability of on-chip solid-state mechanical resonators as light-matter quantum interfaces. The performance we achieved will enable studies of macroscopic quantum phenomena as well as applications in quantum communication, as quantum memories and as quantum transducers.
