The analysis of these properties could provide essential information for future innovative optical photon-to-spin conversion interfaces, long-sought after for entanglement distribution. A 30-band k•p model is used to evaluate the electronic properties in the material for a relatively wide range of energies, and a linear tetrahedron method is employed for the Brillouin zone integrations. Carrier, spin, current, and spin current injection rates are calculated for a bichromatic field of frequencies ω and 2ω.","PeriodicalId":189647,"journal":{"name":"Quantum Nanophotonic Materials, Devices, and Systems 2021","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125989806","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Experimental investigation of these phenomena requires a nanoscale probe that directly interacts with PSD. Here, we propose and demonstrate that the nitrogen-vacancy (NV) center in diamond can be used as a quantum sensor for detecting the spinning nature of photons. This room temperature magnetometer can measure the local polarization of light in ultra-subwavelength volumes through photon-spin-induced virtual transitions. The direct detection of light's spin density at the nanoscale using NV centers in diamond opens a new frontier for studying exotic phases of photons as well as future on-chip applications.","PeriodicalId":189647,"journal":{"name":"Quantum Nanophotonic Materials, Devices, and Systems 2021","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128160730","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We show that this exchange allows boosting the learning of the agent. Another experiment underlines the feasibility of such photonic integrated processors for a homomorphically-encrypted quantum walk computation. This secure quantum computation exploits path- and polarization as degrees-of-freedom for encrypting the input and output of the photonic processor. As last demonstration I will present counter-intuitive quantum communication tasks that are linked to the Zeno effect. As outlook I will discuss technological challenges for the scale up of photonic quantum computers, and our group’s current work for addressing some of those.","PeriodicalId":189647,"journal":{"name":"Quantum Nanophotonic Materials, Devices, and Systems 2021","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132325320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since their discovery, most work on these materials has focused on their electronic properties, whilst their interaction with electromagnetic fields has largely been untouched. In small topological insulator nanoparticles (TINPs) the dispersion relation of the topological surface states is no longer continuous but discretized. This system forms a type of topological quantum dot. \u0000 \u0000By studying the optical transition properties between the states of the topological quantum dot we explore their use as a lasing system.

Routing the current through a parallel electrical connection to set the microbridge back to the superconducting state after photon absorption enabled us to overcome the hysteresis of the state transition. Our approach combines facile fabrication of fast microscale detectors with efficient current redistribution mechanism, enabling prospective applications in quantum photonics which requires accurate estimation of photon arrival events.","PeriodicalId":189647,"journal":{"name":"Quantum Nanophotonic Materials, Devices, and Systems 2021","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130251028","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
