A physics research group at TU Darmstadt, which has received funding of 3.3 million euros as part of the “Quantum Technologies\u201c program of the German federal government, is pursuing ambitious goals.<\/p>\n\n\n\n
\u201cLarger memory units and more processing cores result in increased computing power.\u201d We are all familiar with this classification from the technical specifications of classical computers. This applies even more to quantum computers and quantum simulators. A sufficiently large number of memory cells for storing quantum information \u2013 we speak of quantum bits or qubits in reference to bits as the classical information units \u2013 is required in order for these novel computing systems to exploit their full potential.<\/p>\n\n\n\n
Accordingly, intensive research is being carried out worldwide to develop novel technological platforms for quantum computers and quantum simulators that make it possible to increase the number of qubits with a reduced use of the additional resources required for this. So what is required is the most efficient scalability of the underlying quantum processors, writes TU Darmstadt in a press release<\/a>.<\/p>\n\n\n\n In this worldwide competition, the Institute of Applied Physics at the Technical University of Darmstadt can now provide new impulses. With the \u201cDarmstadt Neutral Atom Quantum Technology Platform (DaNaQTP)\u201d<\/a> project, which is funded by the Federal Ministry of Education and Research (BMBF) by a total of 3.3 million euros as part of the \u201cQuantum Technologies\u201d funding program, Professor Gerhard Birkl\u2019s<\/a> team can significantly develop its architecture for quantum processors, which is particularly ambitious in international comparison, and fully exploit the potential for scalability. The approach is based on a combination of state-of-the-art optical technology with the most advanced methods of quantum optics, which facilitate scalable manipulation of quantum states.<\/p>\n\n\n\n Based on lithographically manufactured microlens arrays, two-dimensional trapping architectures for individual neutral atoms are generated with laser light. Every single atom stores a qubit, which presents the lowest physically achievable limit of material allocation for a qubit. In DaNaQTP, each atom can be individually inscribed with quantum information \u2013 and this can be read out again in a fully controlled manner. The necessary control of one qubit by another qubit \u2013 required for processing information in the quantum processor \u2013 is achieved by the interaction between the atoms in high-lying states, known as Rydberg states.<\/p>\n\n\n\n The central goals of the project are, on the one hand, to develop the quantum memory already demonstrated in Darmstadt into a functional quantum processor with 100 interacting qubits, and on the other to significantly increase the number of memory cells for qubits. Here, the tremendous innovation potential of the DaNaQTP platform comes into its own. The next step with scaling to 1000 qubits is to be achieved during the course of the project. But beyond that, the technological basis used already points the way to quantum processors with 100,000 fully controllable qubits. Currently, only few other platform can predict scalability such explicitly.<\/p>\n\n\n\n Also interesting: <\/strong><\/em>Fraunhofer and QuTech partner up for quantum internet<\/a><\/p>\n","protected":false},"author":2084,"featured_media":324473,"template":"","meta":{"_acf_changed":false,"advgb_blocks_editor_width":"","advgb_blocks_columns_visual_guide":""},"categories":[8553],"tags":[126190,37153,33511,37501,30377],"location":[24456],"internal_archives":[],"class_list":["post-324480","selected","type-selected","status-publish","has-post-thumbnail","hentry","category-digital","tag-federal-ministry-of-education-and-research","tag-quantum-computers","tag-quantum-physics","tag-qubit","tag-tu-darmstadt-en","location-germany"],"blocksy_meta":[],"acf":[],"featured_img":"https:\/\/ioplus.nl\/archive\/wp-content\/uploads\/2022\/04\/kqQgEqcl-20210928_DaNaQTP_ag_birkl_Img160978_870x0-1.jpg","coauthors":[],"author_meta":{"author_link":"https:\/\/ioplus.nl\/archive\/author\/mauro-mereu\/","display_name":"Mauro Mereu"},"relative_dates":{"created":"Posted 4 years ago","modified":"Updated 4 years ago"},"absolute_dates":{"created":"Posted on December 15, 2021","modified":"Updated on December 15, 2021"},"absolute_dates_time":{"created":"Posted on December 15, 2021 4:00 pm","modified":"Updated on December 15, 2021 4:00 pm"},"featured_img_caption":"\u00a9 TU Darmstadt","tax_additional":{"category":{"linked":["Digital<\/a>"],"unlinked":["Digital<\/span>"],"slug":"category","name":"Categories"},"post_tag":{"linked":["Federal Ministry of Education and Research<\/a>","quantum computers<\/a>","quantum physics<\/a>","qubit<\/a>","TU Darmstadt<\/a>"],"unlinked":["Federal Ministry of Education and Research<\/span>","quantum computers<\/span>","quantum physics<\/span>","qubit<\/span>","TU Darmstadt<\/span>"],"slug":"post_tag","name":"Tags"},"language":{"linked":["EN<\/a>"],"unlinked":["EN<\/span>"],"slug":"language","name":"Tags"},"post_translations":{"linked":["pll_61b9ffa0e508b<\/a>"],"unlinked":["pll_61b9ffa0e508b<\/span>"],"slug":"post_translations","name":""},"location":{"linked":["Germany<\/a>"],"unlinked":["Germany<\/span>"],"slug":"location","name":"Locations"},"internal_archives":{"linked":[],"unlinked":[],"slug":"internal_archives","name":"Internal Archives"}},"series_order":"","_links":{"self":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/selected\/324480","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/selected"}],"about":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/types\/selected"}],"author":[{"embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/users\/2084"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/media\/324473"}],"wp:attachment":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/media?parent=324480"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/categories?post=324480"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/tags?post=324480"},{"taxonomy":"location","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/location?post=324480"},{"taxonomy":"internal_archives","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/internal_archives?post=324480"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}New impulses<\/h3>\n\n\n\n
