Quantum information processing relies on the counter-intuitive characteristics of quantum mechanics. But how did this theory appear? And why do we know it is true? What did we learn from it? How can we apply this knowledge? And how come the advent of quantum information processing took so long? These are some of the questions being addressed during this overview. The talk will briefly review the history of quantum mechanics, the lessons we learned and how this knowledge has been applied so far, e.g. the transistor and the laser. Finally, the basics of quantum information processing will be discussed to lay the groundwork for the next talks to come.
After his graduation from the University of Munich with a Diploma in Physics, Thomas Walther moved to the University of Zurich, where he earned his PhD degree with a thesis on quantum beat spectroscopy in 1994. During the same year he joined the Department of Physics at Texas A&M University in College Station, TX as a PostDoc, where he became an Assistant Professor in 1998. In 2002 he returned to Germany as a Full Professor of Physics at TU Darmstadt. His research interests are fundamental quantum effects, quantum cryptography as well as laser spectroscopy and applications.
Discovered in 1993, quantum teleportation is arguably among the most intriguing and fascinating effects of quantum theory. This talk will give a pedestrian introduction to the subject, in particular to the key concept of quantum entanglement. Experimental demonstrations and practical applications in quantum information processing will also be discussed.

The term computer means more than just your average Apple Mac
or PC. A computer, at its most basic level, is any object that can take
instructions, and perform computations based on those instructions. In
this sense computation is not limited to a machine or mechanical
apparatus; atomic physical phenomena or living organisms are also
perfectly valid forms of computers (and in many cases far more powerful
than what we can achieve through our current models).
In my talk I will explain the basic idea behind using quantum systems to perform computation and introduce the notion of quantum bits and quantum gates as the basic elements of any quantum computation. Even though quantum computers are more powerful than any existing (classical) computers, the challenge to build them is still substantial. I will comment on the current state of the art in quantum technologies and explain what the main obstacle is to building large scale quantum computers. Fortunately, as far as we can see there are no fundamental limitations to using quantum systems to compute, and I will explain how quantum error correction can lead us to a fully fledged quantum devices in not too distant a future.

Quantum computers make use of quantum-mechanical effects like superposition, interference, and entanglement. This lecture will explain how quantum algorithms work: by applying a circuit of elementary "quantum gates" on quantum bits. It will then describe some of the fast quantum algorithms that have been found, such as Shor’s algorithm for factoring large integers into their prime factors (which breaks a lot of widely used cryptography), Grover’s algorithm for searching through large databases, and the Harrow-Hassidim-Lloyd algorithm for solving well-behaved systems of linear equations. It will also discuss some known or conjectured limitations of quantum algorithms.

The prospect of large-scale quantum computers forces us to rethink our approach to security of our communication networks already today. In the search of quantum-safe solutions, there are two solutions: classical cryptographic algorithms (post-quantum cryptography) and quantum-based solutions (quantum key distribution [QKD]). QKD protocols provides information-theoretic secure key for two parties using basic principles of quantum mechanics, which means that the security features of this solution does not depend on future technological developments that could play into the hands of an adversary. I will outline the security principles and claims of the protocols, and will also address the performance and security claim of today's implementations.

With the advent of large-scale quantum computers, all current public-key cryptography used in the internet (based on RSA and Elliptic Curves) will be rendered insecure. In this talk I will discuss new approaches to build the next generation of cryptographic protocols that are believed to be secure against attackers equipped with a quantum computer. Cryptography from a mathematical object called "lattices" seems to be among the most promising candidates to withstand quantum attacks. All considered cryptographic protocols are purely classical and do not require quantum computation.

VR-Headset auf und hinein ins Quantenlabor: Im Vorfeld seiner Konferenz "Die Quanten kommen!" hat Golem.de mit Nokias Panoramakamera Ozo ein Forschungslabor besucht und für die Konferenzbesucher Bilder in 360 Grad und 3D mitgebracht.
Das Rennen ist eröffnet: Eine ganze Reihe öffentlicher und privater Forschungsinitiativen bemüht sich um die besten Quantencomputer-Technologien.
Das Rechnen mit Quantenzuständen sollte zuerst ein Problem der Physiker lösen: die seltsame Welt der Quanten zu simulieren. Und vielleicht ist es auch nur dafür sinnvoll.
Bits und Bytes sind für jeden Computer essenziell. Quantencomputer benutzen Qubits zum Rechnen. Was macht sie so besonders?
Neuartiger integrierter Quanten-Schaltkreis-Kühler für heißgelaufene Qubits nutzt Metall-Supraleiter-Tunnelkontakte.
Quantencomputer sind eine Herausforderung für die globale Datensicherheit - aber es gibt bereits Ansätze für ein "quantensicheres" Internet.
Zusammen mit Volkswagen will D-Wave die Rechentechnik revolutionieren und präsentiert dazu stolz eine Quanten-Rechenmaschine auf der Technikmesse Cebit in Hannover. Ob die Technik etwas taugt, muss sie aber noch unter Beweis stellen.
Forscher haben einen praktisch realisierbaren Bauplan für einen universellen Quantencomputer ausgearbeitet. Er soll so groß wie ein Fußballfeld werden und 1.024-Bit-Verschlüsselungen innerhalb von zwei Wochen knacken können.
Quantenkommunikationsnetze und sogar ein Quanteninternet: Die EU hat große Pläne für eine Technologie, die mit großspurigen Behauptungen beworben wird. Doch die dahinterstehenden Quantenschlüsselaustauschsysteme sind weder so sicher wie versprochen, noch lösen sie praktische Probleme.
