Bauteile gegenwärtiger Computer erreichen die Größenordnung von Atomen. Da für atomare und subatomare Physik die Quantenmechanik die akzeptierte und bestens bestätigte Theorie ist, wurde der Vorschlag von Feynman aus dem Jahr 1982 immer aktueller: nämlich Computer zu bauen und Algorithmen zu implementieren, die nach den Prinzipien der Quantenmechanik funktionieren. 
Beim Bau universell programmierbarer Quantencomputer und ihrer Nutzung wurden große Fortschritte erzielt und es gibt Hinweise dafür, dass sie in Zukunft gewisse Aufgabenstellungen wesentlich effizienter lösen können als klassische Computer. Ein viel diskutiertes und beachtetes Beispiel ist die Entschlüsselung aktuell verwendeter, bisher als sicher geltender Verschlüsselungsverfahren.  
Es ist nicht überraschend, dass gerade die der Anschauung am stärksten widersprechenden und daher im Anfangsstadium der Theorie am heftigsten kritisierten Konzepte der Quantenmechanik, wie Superposition und Verschränkung von Zuständen in verschiedenen Anwendungen einen Quantencomputer einem klassischen Computer überlegen machen. 
In der Vorlesung wollen wir insbesondere auf die Verknüpfung von Physik und Informatik in der Quanteninformationstheorie eingehen. 
 - Wir beginnen mit einer Vorstellung aktueller Herausforderungen der Digitalisierung und bekannter Grenzen (klassischer) Computer und geben eine kurze Einführung in Berechenbarkeitstheorie, Rechenmodelle, Algorithmen und reversibles Rechnen. Danach werden das Quantenbit und Rechenschritte darauf definiert, Quantenregister und Quantenschaltkreise eingeführt, wichtige Algorithmen untersucht und gezeigt, wie diese implementiert werden können.
 - Im Zusammenhang mit der Quanteninformatik wird der formale Aufbau der Quantenmechanik noch einmal vorgestellt. Dabei werden die Aspekte, die für die Funktionsweise eines Quantencomputers wesentlich sind, besonders hervorgehoben, z.B. Messprozess, E. Schmidt´scher Formalismus, Quantenkanäle, Superoperatoren und die Quanten-Fouriertransformation.
 - In einem dritten Teil wird die klassische Komplexitätstheorie kurz vorgestellt, um mögliche entscheidende Vorteile eines Quantencomputers aufzeigen zu können.
 - Der nächste Teil der Vorlesung besteht in einer Beschreibung und Diskussion des Shore´schen Algorithmus. Er beruht auf Ergebnissen der Zahlentheorie und der Quanten-Fouriertransformation. Er ist nicht nur der Algorithmus, der aktuell für die größte Aufmerksamkeit sorgt, sondern an ihm lassen sich auch die wesentlichen Vorteile des Quantencomputers und Elemente der Quantenkomplexität sehr gut darstellen.
 - Ein weiterer essentieller Punkt für die Entwicklung der Quantencomputer war die Entdeckung von Verfahren zur Fehlerkorrektur, die wir in diesem Teil der Vorlesung betrachten werden.
 - Die Eigenschaften der Quantenmechanik erlauben die Implementierung abhörsicherer, verschlüsselter Kommunikation. Diese wurde bereits über viele 100 km erfolgreich getestet (Nobelpreis für Physik 2022) und ist wesentliche Voraussetzung für ein Quanteninternet.
 - Abschließend sollen verschiedene Ansätze zum Bau von Quantencomputern und zur Realisierung von Gates vorgestellt werden.

Content

We derive the thermal ground state for the deconfining phase of SU(2) Yang-Mills Thermodynamics, discuss its thermal quasiparticle excitations, and compute the polarization tensor of the effective massless gauge mode. Next, we use these results under the postulate that thermal photon gases of sufficiently large spatial volumes are described by an SU(2) rather than a U(1) gauge principle. For the CMB this gives rise to a modified temperture-redshift relation with an interesting link to 3D Ising criticality. Moreover, we argue that the CMB large-angle anomalies may be traced to SU(2) screening effects and that an axial anomaly with chiral symmetry breaking at the Planck scale yields an ultralight axion particle whose temperature dependent mass essentially is determined by the SU(2) thermal ground state. The super-horizon sized condensate of these particles is a candidate for dark energy. To test the above postulate
recents results of a terrestial blackbody-cavity experiment are discussed and interpreted in the context of SU(2) Yang-Mills thermodynamics.

 Objectives: instanton, Matsubara sum, caloron, thermal ground state, thermal quasiparticle dispersion law, critical exponent, cosmological model, Veneziano-Witten, emissivity, Dicke switch, difference of dBm of noise power
