Quantum entanglement is frequently mediated through the use of single photons, which immediately means that any loss in components can be catastrophic to quantum systems. 11 Some of these areas include aerospace, communications, health care, food, and energy, with many set to benefit from quantum photonics technologies. 10 A report released by the Institute of Physics in May 2018 described the “health of photonics” and highlighted many of the areas that this technology feeds into. 9 A report by the Photonics Leadership Group revealed that the UK photonics industry is worth around £12.9 billion (GBP) and employs > 65, 000 people. Photonics is a major part of modern quantum science, with photons being the main route for mediating quantum interactions, entanglement, and measurement. The first round of the UKNQT was summarized and reviewed by Knight and Walmsley in Quantum Science and Technology, 8 which includes an outlook toward the new hubs and the commercialization of quantum technologies. These hubs have since been superseded by four new hubs that feature updated goals and directions to the research, with strong input from industry to guide the technology developed over the last seven years to commercialization. 7 This is the largest of the four hubs and is working toward building a hybrid quantum computer linking light and matter technologies for quantum information processing. 6 The fourth hub, and the focus of the work presented here, is the NQIT hub led by the University of Oxford. The first round of the hub ran from 2014 to 2019 and consisted of the Sensors and Metrology hub led by Birmingham University 4 the Communications Technologies hub led by the University of York 5 the Quantum Enhanced Imaging hub (QuantIC) led by the University of Glasgow. 3 Part of this is an Engineering and Physical Sciences Research Council (EPSRC) funded national network of four different quantum technology hubs, with each focusing on a different aspect of quantum science and technology. The £270 million (GBP) UK National Quantum Technologies Programme 2 (UKNQTP) is designed to bring together academia, industry, and government as part of a strategy to develop the UK as a future leader in quantum technology. We will also discuss the reception of the device and any feedback given, as well as lessons learned over the course of the project. This paper discusses the motivation behind the project, the design, and construction of the demonstrator, as well as suggestions for a more accessible “home-made” model for the education of quantum entanglement. The unit has also been exhibited at the annual Southampton University Science and Engineering Festival as well as featuring on the university roadshow stand at the New Forest Show in 2019. The demonstrator was part of the Quantum City stand at the 2018 Cheltenham Science Festival-one of the UK’s leading public engagement and science outreach events-and was exhibited with a handout for visitors to take away with them explaining the importance of photonics for quantum technologies. 1 The system was exhibited at 2017, 2018, and 2019 UK Quantum Showcase in London to an audience of industry representatives and government policymakers, and was also featured at the 2018 Innovation South showcase at Farnborough Conference Centre. This work was presented previously at SPIE Optics Education and Outreach V conference, and this paper serves to present and renew the findings. The software was developed to accompany the demonstrator to show how the real-world device works on a single-photon level. In this paper, we present a project by the lead author in developing an interactive demonstrator of a key optical component of the NQIT project to showcase it to a wider audience. However, with the increasing interest in quantum technologies and their impact in the future, it is important to engage people with this science and technology. A key part of this project involves building an optical network to support the construction of a quantum computer.ĭue to the complex nature of quantum science, it is often seen as a difficult area for engagement and outreach. The Networked Quantum Information Technologies (NQIT) hub is one of the four quantum hubs from the first round of the United Kingdom’s (UK’s) flagship scheme, bringing together academia, industry, and government to develop the UK as a leader in quantum technology.
