Description: Nanogrippers allow structures with at least one dimension being of order 100 nm or smaller to be manipulated in a predictable manner. Such grippers consist of one or more actuators, which determine the gap between two or more end-effectors. The actuators are operated through variations of a physical quantity, which is typically an electrical current or voltage, but might also be the temperature, a magnetic field, or even light. While there is a wide selection of actuators available for conventional microelectromechanical systems (MEMS), nearly all nanogrippers which have been demonstrated in practical manipulation of nanostructures so...

Moreover, a photonic platform is a natural choice for testing foundational aspects of quantum mechanics. Most seminal experiments in quantum mechanics, including the work that led to the 2022 Nobel prize in Physics, have been done using photons Aspect et al., 1981, Aspect et al., 1982; Bouwmeester et al., 1997; Clauser & Shimony, 1978; Freedman & Clauser, 1972; Giustina et al., 2015, Giustina et al., 2017. How do we create single photons or, for that matter, entangled photons? A large part of this chapter will be devoted to discussing the means to generate single photons. We will see that there are two broad generation schemes: probabilistic and deterministic. In the former, one cannot deterministically generate single photons on demand, while the latter lends itself to such possibilities. We will specifically discuss spontaneous parametric downconversion (SPDC) and four wave mixing (FWM) as examples of probabilistic photon generation and quantum dots (QD) as well as color centers in diamond, including nitrogen-vacancy (NV) centers, as examples of deterministic photon generation. We will study in detail the various properties that determine the quality of the photon source. In the second part of the chapter, we will discuss the usage of single and entangled photons in different quantum technology applications. We will specifically focus our attention on two major applications, i.e., Quantum Communications and Quantum Computing. Next, we go on to discuss the various properties that single photons need to satisfy. Description: Restricted Access Sun, 01 Jan 2023 00:00:00 GMT http://hdl.handle.net/2289/8156 2023-01-01T00:00:00Z
