The relevance of SDN as a suitable approach for a real integration between QKD and WDM networks is presented, together with the description of novel rateless error correcting codes (ECC) suitable for QKD reconciliation. Preliminary experimental results on a discrete-variable QKD field trial, over production optical fibers deployed in the metropolitan area of Turin in presence of high-bitrate classic channels, are reported. Stable performance on a week-long interval is demonstrated, showing the capabilities of QKD in short/medium reach optical networks. This work is part of the activities of the PON project “Development of quantum systems and technologies for IT security in communication networks” (QUANCOM) which aims to the realization of a metropolitan quantum communication network through the collaboration between universities, research centers and companies operating in the communication market area.","PeriodicalId":299229,"journal":{"name":"2022 IEEE 15th Workshop on Low Temperature Electronics (WOLTE)","volume":"153 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123602956","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}

Quantum computing systems with high-fidelity control and readout, coherent coupling, calibrated gates, and reconfigurable circuits with low error rates are expected to have superior quantum volumes. Cryogenic CMOS plays a crucial role in the realization of scalable quantum computers, by minimizing the feature size, lowering the cost, power consumption, and implementing low latency error correction. Our approach toward achieving scalable feed-back based control systems includes the design of memory based arbitrary waveform generators (AWG’s), wide band radio frequency analog to digital converters, integrated amplifier chain, and state discriminators that can be synchronized with gate sequences. Digitally assisted designs, when implemented in an advanced CMOS node such as 7 nm can reap the benefits of low power due to scaling. A qubit readout chain demands several amplification stages before the digitizer. We propose the co-integration of our in-house developed InP HEMT LNAs with CMOS LNA stages to achieve the required gain at the digitizer input with minimal area. Our approach using high impedance matching between the HEMT LNA and the cryogenic CMOS receiver can relax the design constraints of an inverter-based CMOS LNA, paving the way toward a fully integrated qubit readout chain. The qubit state discriminator consists of a digital signal processor that computes the qubit state from the digitizer output and a pre-determined threshold. The proposed system realizes feedback-based optimal control for error mitigation and reduction of the required data rate through the serial interface to room temperature electronics.","PeriodicalId":299229,"journal":{"name":"2022 IEEE 15th Workshop on Low Temperature Electronics (WOLTE)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132701894","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}

It is even very often the limitation to the number of channels of the experiments.To tackle this, we have developed a very innovative hybridization technology allowing the interconnections, by a large number of links, of two devices (typically a sub-K detector and the first stage of its readout electronics) cooled at different temperatures (typically 50 mK and 0.3 – 1 K). These hybridizations present a very low electrical resistance and an extremely high thermal resistance, unmatched by existing technologies, thanks to a multilayer superconducting metallization technology.The very low thermal conduction (much lower than the phonon conduction in a homogeneous superconducting material) is obtained thanks to an acoustic mismatch between layers. The link is ultra-compact (≃ μm) and with ultra-low electrical impedance thanks to the use of superconducting materials only. It can be used to interconnect devices, for example when associated with ball hybridization, or inside the elementary cells of low temperature detectors, for example to separate the two functions of absorption and thermometry. So this new process could transform drastically, in the future, the architecture of nearly all sub-K instrumentations.We have already realized such device at the Plateforme Technologique Amont (PTA) Grenoble facility. Measurements in the sub-K range demonstrate very interesting thermal performances. In this paper, we present the principle behind this thermal property of this Multi-Layer, the first results, and the perspectives.","PeriodicalId":299229,"journal":{"name":"2022 IEEE 15th Workshop on Low Temperature Electronics (WOLTE)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134166540","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}
