Dear Reader, Since the launch of our journal Advanced Quantum Technologies (QUTE for short) in 2018, we have been witnessing plenty of very promising research initiatives and activities in the diverse fields of quantum science, quantum materials, and quantum technologies. Key questions like “Where is quantum technology taking us? What are challenges and perspectives?” led our Editorial Advisor Rainer Blatt to edit a special issue Advancing Quantum Technologies – Chances and Challenges that we published in November 2020 (https://onlinelibrary.wiley.com/toc/25119044/2020/3/11). It broadly showcases how to master quantum phenomena for communication, metrology, sensing, simulation, and computation purposes. In a related virtual mini-symposium Rainer Blatt invited the authors Christoph Becher, Dagmar Bruss, Klemens Hammerer, Dieter Meschede, Christian Ospelkaus, and Robert Raussendorf to share their visions of the quantum future, which culminated in a vivid discussion (https://www.workcast.com/register?cpak=6284277449925096). Yet another recent quantum science webinar targeting a large Chinese audience featured our authors Tongcang Li and Yongjian Han who gave talks on quantum simulation in optical systems and quantum spin optomechanics, respectively. Further activities are being planned for 2021 in order to stay in close contact with the quantum community even during the pandemic. Earlier in 2020 Mohamed Benyoucef, Anthony Bennett, Stephan Götzinger, and Chaoyang Lu threw the spotlight on Photonic Quantum Technologies by editing a special issue (https://onlinelibrary.wiley.com/toc/25119044/2020/3/2). The topics addressed include hybrid integration of single-photon emitters, cavity QED and light–matter interactions at the nanoscale, on-chip integration of entangled photon sources, and incorporating color centers into nanophotonic structures. Fabrication of suspended converters, single-photon emission at the telecom wavelength, molecule-based single-photon sources, quantum emitter–plasmonic cavity coupling, vertically coupled quantum dot systems, and optomechanical coupling are also discussed. We are happy to announce that our young and growing journal is being indexed in Web of Science. We are confident that the enhanced visibility of QUTE will trigger increasing submission numbers and a growing impact on the thriving field of quantum science and technology.

2019 promises to be a crucial year for the emerging field of quantum technologies. On the funding side, the Quantum Technologies Flagship of the European Union has kicked off with the first 20 projects,1 and the total funding is expected to reach €1bn over the coming decade.2 Other world regions are not being left behind: In the US, Congress has recently passed the National Quantum Initiative Act, likewise a 10-year program with a budget of $1.3bn. This bold concept is accompanied by further support from government agencies such as the DOE and NSF. Research activities are being intensified not only in academia and research laboratories but also in the R&D centers of giant corporations such as Google, IBM, Microsoft and in many other companies. A key goal is to couple ever more qubits and to demonstrate a working quantum computer that will be able to achieve the ‘holy grail’ of quantum supremacy in computational power – if not yet today or tomorrow, then certainly in the years to come. Last but not least, the Chinese government has announced the provision of no less than $10bn to create a National Laboratory for Quantum Information Sciences. China has already taken crucial steps in creating a quantum network, including satellite-based communication. So, clearly the world is not short of opportunities in pursuing new and exciting quantum science, as well as its applications. On the other hand, it is more than obvious that there are still many fundamental scientific questions to be solved, not to speak of the development of real technologies that are still in their infancy to be implemented on a broader scale. Our journal Advanced Quantum Technologies (QUTE) (www.advquantumtech.com), a young member of the renowned Advanced journal family published by Wiley-VCH, aims to provide a peer-reviewed high quality forum for these topics, ranging from the theoretical basics to future device applications. Key areas include quantum-based communication, computation, control, engineering, information, metrology, optics, sensing and simulation, as well as adjacent areas such as nanophotonics, quasiparticle excitations, topological materials, superconductors, micro- and nano-electromechanical systems, ultracold atoms and others. The first three issues published in 2018 already provided a glimpse of our intended broad topical spectrum, with Reviews on continuous-variable quantum key distribution,3 non-equilibrium Bose–Einstein-like condensation4 and integrated quantum photonics based on diamond,5 accompanied by original research contributions as Communications or Full Papers. Now, what do we have in store for the New Year: The present issue features, for example, a Review on topological insulators and semimetals for magnetoresistive sensors6 and a Progress Report on the Dicke model being relevant for quantum optics.7 Later during 2019, we also plan to present two special issues on the topics of Quantum Machine Learning and Photonic Quantum Technologies that will aim to provide a snapshot of the state-of-the-art in these respective fields. Most importantly, please be reminded that the journal is open for original research submissions at www.editorialmanager.com/advquantumtech as well as your proposals for review-type contributions that you may send to advquantumtech@wiley.com at any time. We will also use forthcoming conference opportunities such as the APS March Meeting in Boston, several DPG (German Physical Society) meetings as well as various events in Asia to meet with you personally to get to know your research, to invite you to submit as well to learn more about the publication needs of the quantum community. Feel free to get in touch with us through any physical or virtual channel! For those of you who might be new to our journals: Online submission and online publication (no print) in QUTE are completely cost-free, and the journal is also free-to-read for anybody during the whole year. If you would like to make use of open-access options, Wiley OnlineOpen with various open access licenses is available through an increasing number of national, consortial or funder agreements (such as the ‘DEAL’ soon to be implemented in Germany8) or via payment of the respective article publication charge by your institution or funder. Details are provided in the ‘Contribute’ section of our homepage. You may also post a preprint of your manuscript to arXiv.org or similar servers, or to a scientific collaboration network that is compliant with the STM sharing principles.9 When doing so, please make sure that the journal reference is always up to date, including the DOI and/or URL of your journal-published article. More information on general article sharing principles is available on howcanishareit.com. These should help you to achieve maximum visibility both of your newest publication and of our young journal, as will news stories on selected top content on our news portal advancedsciencenews.com. We look forward to exciting quantum times and to reading (or hearing) from you! The Editorial Team of Advanced Quantum Technologies
The purpose of this issue is to highlight the recent progress and trends in the development of novel nano- and quantum photonic technologies. The articles published in this issue cover a broad range of areas, including: 1) novel nanophotonic light sources-both classical (lasers) and nonclassical (single- and entangled photon sources); 2) nonlinear optics in nanophotonic structures; 3) quantum optics and quantum information processing based on nanophotonics platform; 4) efficient devices for optical interconnects and optical information processing based on novel nanophotonic structures. This issue contains 25 papers, including eight invited, authored by well-established research groups and promising scientists from all over the world. The invited articles include extended reviews on entangled photon generation using silicon nanowire waveguides; cavity quantum electrodynamics and lasing oscillation in single quantum dot photonic crystal nanocavity systems; quantum plasmonic circuits; theoretical analysis of few-photon single-atom cavity quantum electrodynamics; semiconductor quantum dot micropillar microcavities for quantum optics in solid state; nanofiber-based optical trapping of cold neutral atoms; switching and counting with atomic vapors in photonic-crystal fibers; and production of multiple diamondbased single-photon sources. The contributed articles cover a broad variety of key nanophotonics and quantum photonics research areas, including recently obtained results on bright single-photon emission from a quantum dot in a circular Bragg grating microcavity, supercontinuum generation in nanostructured silicon waveguides, electrically driven photonic crystal nanocavity devices, and silicon quantum dots.
In recent years, the field of quantum nanophotonics has been thriving with an intense interest in the development of new theories, devices, and applications for specific uses.This special issue on "Quantum nanophotonics" highlights some recent developments in this topic through reviews, perspectives, and research papers.This issue contains review and perspective articles that provide a comprehensive overview of cutting-edge topics.Chang and Zwiller [1] review the recent progresses in integrated quantum photonics using nanowires, focusing on integrated emitters, detectors, and fabrication methods.This review also presents the applications for quantum information processing and sensing based on nanowires.Gali [2] summarizes the ab initio theory to fully understand solid-state qubits, which are an essential component in the quantum photonic device.This computational method has been applied to the calculation of excited states, photo-ionization threshold, optical excitation spectra, effective mass states, and spin dynamics.This approach could give insights beyond conventional density functional theory that cannot fully capture the characteristics of excited states.Biotechnologies are being used in a variety of quantum optics and photonics or vice versa.DNA nanotechnology, using the information of DNA to design and manufacture artificial nucleic acid structures for technological uses, has been utilized in the field of quantum emitters.Exotic traits of DNA enable the grabbing of quantum emitters and steering of their directors at the molecular level of resolution.The relevant studies were extensively reviewed by Cho et al. [3].Reversely, the understanding of light-matter interaction in quantum optics provides a hint to investigate chemical and biological processes.Kim et al. [4] present a review of plexcitonic and vibro-polaritonic strong coupling based on light-matter interaction with optical resonators.The authors introduce from fundamentals of strong coupling, configuration and characteristics of plexcitons, and applications for chemistry and biological detection.Kim et al. [5] discuss that nanophotonic resonance engineering can make the near-unity readout fidelity necessary for improving the sensitivity of NV quantum sensing.The perspective gives insight into the background of NV quantum sensing, applications of resonant structures, and the remaining challenges for practical sensing.Zheng and Kim [6] address the degradation mechanisms of perovskite-based light-emitting diodes.The degradation can potentially occur in external and internal processes, leading to distinct effects on performance and stability.Various research articles on quantum nanophotonics are included.There is growing interest in optimizing the single photon emitter (SPE) that can be integrated into the photonic circuit and enable practical application.Azzam et al. [7] demonstrate the Purcell enhancement of WSe 2 SPE using a dielectric cavity.The dielectric cavity imposes an oriented strain profile on the WSe 2 , which can make the polarization state of the SPE selectively controlled.Xu et al. [8] report a high-purity SPE based on nanodiamonds (NDs) with negatively charged silicon vacancy (SiV -) centers using an ion implantation method.They successfully prevent SiV -emitters from
