Superconductivity, discovered 114 years ago, stands as a prime example, offering direct and compelling evidence of macroscopic quantum phenomena. Beyond its ability to conduct immense currents without loss, superconductivity reveals the quantum realm operating on a scale we can directly observe and manipulate. The macroscopic quantum coherence, where an ensemble of particles is described by a single wave function, leads to remarkable consequences: dissipation-less current and flux quantization – the basic properties exploited in superconducting quantum circuit fabrication. This Roadmap has been inspired by intensive discussions and collaborations emerging from the European Cooperation in Science & Technology COST-Action CA21144 (SuperQuMap – Superconducting Nanodevices and Quantum Materials for Coherent Manipulation). The aim of the COST Action SuperQuMap is to establish a strong European network centered on macroscopic quantum behavior in superconductors, bringing together groups of different backgrounds and more than 30 countries. The roadmap outlines the network’s concrete activities, driving advancements in superconductor-based quantum technologies and charting future directions. Spanning fundamental research to practical applications, the roadmap incorporates insights from industry partners developing quantum computation. It begins by exploring quantum materials, highlighting how topology and electronic correlations could catalyze a quantum leap in technology. We then delve into manipulating the superconducting phase, leveraging advancements in magnetism, 3D fabrication, and tunable correlations. Further, we showcase the advanced microscopy techniques—such as angle-resolved photoemission spectroscopy and scanning probes—used to visualize quantum behavior. Finally, and crucially, we detail the quantum devices developed within the network, and their transformative impact on modern quantum computing approaches. 000167845 536__ $$9info:eu-repo/grantAgreement/ES/MICINN/PID2021-124680OB-I00 000167845 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttps://creativecommons.org/licenses/by/4.0/deed.es 000167845 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000167845 700__ $$aSuderow, Hermann 000167845 700__ $$aTafuri, Francesco 000167845 700__ $$aBlack-Schaffer, Annica 000167845 700__ $$aLado, Jose 000167845 700__ $$aSudbo, Asle 000167845 700__ $$aStornaiuolo, Daniela 000167845 700__ $$aLi, Chuan 000167845 700__ $$aBöhmer, Anna E. 000167845 700__ $$aTran, Lan Maria 000167845 700__ $$aZaleski, Andrzej J 000167845 700__ $$aCrisan, Adrian 000167845 700__ $$aPolichetti, Massimiliano 000167845 700__ $$aGalluzzi, Armando 000167845 700__ $$aGencer, Ali 000167845 700__ $$aAichner, Bernd 000167845 700__ $$aBarisic, Neven 000167845 700__ $$aLang, Wolfgang 000167845 700__ $$aSamuely, Tomas 000167845 700__ $$aGmitra, Martin 000167845 700__ $$aCren, Tristan 000167845 700__ $$aCalandra, Matteo 000167845 700__ $$aSamuely, Peter 000167845 700__ $$aCusters, Jeroen 000167845 700__ $$aCordoba, Rosa 000167845 700__ $$aFomin, Vladimir M 000167845 700__ $$aPoccia, Nicola 000167845 700__ $$aSzabó, Pavol 000167845 700__ $$aPorrati, Fabrizio 000167845 700__ $$aKakazei, Gleb N 000167845 700__ $$aAarts, Jan 000167845 700__ $$aRobinson, J W A 000167845 700__ $$aVillegas, Javier 000167845 700__ $$aAlthammer, Matthias 000167845 700__ $$aHuebl, Hans 000167845 700__ $$aKamra, Akashdeep 000167845 700__ $$aWeiler, Mathias 000167845 700__ $$aDil, Hugo Jan 000167845 700__ $$aYevtushynsky, Daniil 000167845 700__ $$aKalisky, Beena 000167845 700__ $$aAnahory, Yonathan 000167845 700__ $$aBending, Simon J 000167845 700__ $$aLiljeroth, Peter 000167845 700__ $$aHassanien, Abdou 000167845 700__ $$aGuillamón, Isabel 000167845 700__ $$aHerrera, Edwin 000167845 700__ $$aSilhanek, Alejandro 000167845 700__ $$aVan de Vondel, Joris 000167845 700__ $$aPalau, Anna 000167845 700__ $$aCharaev, Ilya 000167845 700__ $$aSidorova, Mariia 000167845 700__ $$aLombardi, Floriana 000167845 700__ $$aBauch, Thilo 000167845 700__ $$aFeuillet-Palma, Cheryl 000167845 700__ $$aStolyarov, Vasily 000167845 700__ $$aRoditchev, Dimitri 000167845 700__ $$aKrasnov, Vladimir M 000167845 700__ $$aHampel, Benedikt 000167845 700__ $$0(orcid)0000-0002-8125-877X$$aMartinez Perez, Maria Jose 000167845 700__ $$0(orcid)0000-0002-7742-9329$$aSese, Javier 000167845 700__ $$aKoelle, Dieter 000167845 700__ $$aPoletto, Stefano 000167845 700__ $$aBruno, Alessandro 000167845 700__ $$aMassarotti, Davide 000167845 773__ $$g(2025), [123 pp.]$$pSupercond. sci. technol.$$tSuperconductor Science and Technology$$x0953-2048 000167845 8564_ $$s4082987$$uhttps://zaguan.unizar.es/record/167845/files/texto_completo.pdf$$yPostprint 000167845 8564_ $$s1257640$$uhttps://zaguan.unizar.es/record/167845/files/texto_completo.jpg?subformat=icon$$xicon$$yPostprint 000167845 909CO $$ooai:zaguan.unizar.es:167845$$particulos$$pdriver 000167845 951__ $$a2026-01-21-14:54:44 000167845 980__ $$aARTICLE
