Hong-Ou-Mandel Effect Quantum Light University of Sheffield 2014-05-29 | An animation explaining how two indistinguishable single photons that simultaneously enter a beam splitter will always leave together. We are developing miniaturised semiconductor structures like the one shown in the animation to demonstrate the Hong-Ou-Mandel effect. Our overall goal is to interface static qubits (exciton or spin states in quantum dots) with flying qubits (photons), in order to demonstrate the key components of quantum networks.

Quantum Telescopes Quantum Light University of Sheffield 2024-10-04 | Discovering the secrets of the universe requires increasingly sensitive telescopes. In this video we show how we can use quantum technologies to improve the resolution of existing telescopes.
Twistronics: building moiré superlattices from 2D materials Quantum Light University of Sheffield 2023-01-09 | Follow up to our previous video on van der Waals heterostructures, 2D Materials Beyond Graphene.When ultrathin two-dimensional materials are stacked together to build designer nanomaterials, they can be twisted relative to one another, such that the atoms in each layer line up differently. This twisting, which is not possible in most present-day thin film nanotechnology, can lead to enormous changes of the material properties. The great potential on offer has given rise to a new field of scientific research termed "twistronics", which seeks to discover new functionality by taking two-dimensional materials and adding a twist.Written and directed by Tom Lyons in collaboration with Alexander Tartakovskii's research group.Produced by Gareth Jones, 23i.co.uk
Making Quantum Light with Quantum Dots Quantum Light University of Sheffield 2022-02-24 | This animation explores how we can use semiconductor "quantum dots" to create quantum light for applications in quantum communications, computing and sensing. A quantum dot is a nano-scale defect in a semiconductor that confines single charge particles (electrons). This video shows how we make quantum dots and how we can use them as a source of single particles of light (photons) for quantum technologies. At the University of Sheffield, we are using these techniques to produce nano-photonic semiconductor chips to power the next generation of optical quantum technologies.Learn more at:LDSD Sheffield Research Group - ldsd.group.shef.ac.ukSheffield Quantum Center - quantum.shef.ac.ukDIRECTED BY:Alistair J.

Topological Quantum Error Correction Quantum Light University of Sheffield 2018-09-28 | How can we protect the fragile quantum states to make real-world quantum computing and applications? In this video, we explain why qubits made of single particles are so sensitive and how, in principle, to go around this problem to make robust qubits.Learn more about our research:ldsd.group.shef.ac.uksheffield.ac.uk/physicsearltcampbell.comFollow us on Twitter:twitter.com/ldsd_researchtwitter.com/PhysicsSheftwitter.com/sheffielduniDIRECTED BYMaksym SichWRITTEN BYMaksym SichEarl T.

Timelapse Building an Optics Lab for Studies of 2D Materials Quantum Light University of Sheffield 2017-09-19 | We have built our new lab for studies of optical properties of structures based on 2D materials (youtu.be/jkAXhJWixJ8), such as MoS2, MoSe2, WSe2, WS2, NbSe2, gallium and indium chalcogenides. The University of Sheffield is amongst the leaders in research of complex heterostructures based on 2D materials which is based on our expertise in photonics and magneto-optics of nanostructured semiconductors.Learn more about our research: ldsd.group.shef.ac.uk/research/2d-materialsProduced by Emiliano Cancellieri & Luca SortinoFilmed & Edited by James ParsonsTechnical Support: Giuseppe Buonaiuto & Maksym SichSpecial Thanks to Marie Skłodowska-Curie Actions, Graphene Flagship, EPSRC, and Prof. Alexander I.

2D Materials Beyond Graphene Quantum Light University of Sheffield 2016-10-28 | In this animation, the next gen. of optoelectronic devices based upon the physics and tech. of layered 2D materials is presented. Following the discovery of graphene a host of other 2D materials have been discovered with a wide range of different properties. We explain the concept and unique properties of 2-dimensional materials and show that by stacking different 2D materials into carefully constructed stacks, these properties can be combined to produce artificial materials known as van der Waals heterostructures with tailor-made properties. Such systems are at the forefront of semiconductor research of which our research group in Sheffield is actively contributing: http://ldsd.group.shef.ac.uk/research/2d-materialsFor more info check out our website: http://ldsd.group.shef.ac.ukFollow us on Twitter: http://twitter.com/ldsd_researchDIRECTED BYScott DufferwielMaksym SichPRODUCED BYGareth Jones, 23i.co.ukWRITTEN BYScott DufferwielThomas P.
