Rainer Blatt
Rainer Blatt (born 8 September 1952) is a German-Austrian experimental physicist. His research centres on the areas of quantum optics and quantum information. He and his team performed one of the first experiments to teleport atoms, the other was done at NIST in Boulder Colorado. The reports of both groups appeared back-to-back in ''Nature''. Early life and education Blatt graduated in physics from the University of Mainz in 1979. He finished his doctorate in 1981 and worked as research assistant in the team of Günter Werth. Career In 1982 Blatt received a research grant of the Deutsche Forschungsgemeinschaft (DFG) to go to the Joint Institute for Laboratory Astrophysics (JILA), Boulder, and work with John L. Hall (Nobel Prize winner 2005) for a year. In 1983 he went on to the Freie Universität Berlin, and in the following year joined the working group of Peter E. Toschek at the University of Hamburg. After another stay in the US, Rainer Blatt applied to qualify as a profess ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Idar-Oberstein
Idar-Oberstein () is a town in the Birkenfeld district in Rhineland-Palatinate, Germany. As a ''Große kreisangehörige Stadt'' (large city belonging to a district), it assumes some of the responsibilities that for smaller municipalities in the district are assumed by the district administration. Today's town of Idar-Oberstein is the product of two rounds of administrative reform, one in 1933 and the other in 1969, which saw many municipalities amalgamated into one. The various '' Stadtteile'' have, however, retained their original identities, which, aside from the somewhat more urban character encountered in Idar and Oberstein, tend to hearken back to each centre's history as a rural village. Idar-Oberstein is known as a gemstone town, and also as a garrison town. It is also the largest town in the Hunsrück. Geography The town lies on the southern edge of the Hunsrück on both sides of the river Nahe. Constituent communities The following are the divisions within the town ...

Freie Universität Berlin
The Free University of Berlin (, often abbreviated as FU Berlin or simply FU) is a public research university in Berlin, Germany. It is consistently ranked among Germany's best universities, with particular strengths in political science and the humanities. It is recognised as a leading university in international university rankings. The Free University of Berlin was founded in West Berlin in 1948 with American support during the early Cold War period as a Western continuation of the Friedrich Wilhelm University, or the University of Berlin, whose traditions and faculty members it retained. The Friedrich Wilhelm University (which was renamed the Humboldt University), being in East Berlin, faced strong communist repression; the Free University's name referred to West Berlin's status as part of the Western Free World, in contrast to communist-controlled East Berlin. In 2008, as part of a joint effort, the Free University of Berlin, along with the Hertie School of Governance, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quantum Information Processing
Quantum information science is an interdisciplinary field that seeks to understand the analysis, processing, and transmission of information using quantum mechanics principles. It combines the study of Information science with quantum effects in physics. It includes theoretical issues in computational models and more experimental topics in quantum physics, including what can and cannot be done with quantum information. The term quantum information theory is also used, but it fails to encompass experimental research, and can be confused with a subfield of quantum information science that addresses the processing of quantum information. Scientific and engineering studies To understand quantum teleportation, quantum entanglement and the manufacturing of quantum computer hardware requires a thorough understanding of quantum physics and engineering. Since 2010s, there has been remarkable progress in manufacturing quantum computers, with companies like Google and IBM investing heavily ...

Quantum Metrology
Quantum metrology is the study of making high-resolution and highly sensitive measurements of physical parameters using quantum theory to describe the physical systems, particularly exploiting quantum entanglement and quantum squeezing. This field promises to develop measurement techniques that give better precision than the same measurement performed in a classical framework. Together with quantum hypothesis testing, it represents an important theoretical model at the basis of quantum sensing. Mathematical foundations A basic task of quantum metrology is estimating the parameter \theta of the unitary dynamics \varrho(\theta)=\exp(-iH\theta)\varrho_0\exp(+iH\theta), where \varrho_0 is the initial state of the system and H is the Hamiltonian of the system. \theta is estimated based on measurements on \varrho(\theta). Typically, the system is composed of many particles, and the Hamiltonian is a sum of single-particle terms H=\sum_k H_k, where H_k acts on the kth particle. ...

Spectroscopy
Spectroscopy is the field of study that measures and interprets the electromagnetic spectra that result from the interaction between electromagnetic radiation and matter as a function of the wavelength or frequency of the radiation. Matter waves and acoustic waves can also be considered forms of radiative energy, and recently gravitational waves have been associated with a spectral signature in the context of the Laser Interferometer Gravitational-Wave Observatory (LIGO) In simpler terms, spectroscopy is the precise study of color as generalized from visible light to all bands of the electromagnetic spectrum. Historically, spectroscopy originated as the study of the wavelength dependence of the absorption by gas phase matter of visible light dispersed by a prism. Spectroscopy, primarily in the electromagnetic spectrum, is a fundamental exploratory tool in the fields of astronomy, chemistry, materials science, and physics, allowing the composition, physical structure and e ...

Experimental Physicist
Experimental physics is the category of disciplines and sub-disciplines in the field of physics that are concerned with the observation of physical phenomena and experiments. Methods vary from discipline to discipline, from simple experiments and observations, such as Galileo's experiments, to more complicated ones, such as the Large Hadron Collider. Overview Experimental physics encompasses all the disciplines of physics that are concerned with data acquisition, data-acquisition methods, and the detailed conceptualization (beyond simple thought experiments) and realization of laboratory experiments. It is often contrasted with theoretical physics, which is more concerned with predicting and explaining the physical behaviour of nature than the acquisition of empirical data. Although experimental and theoretical physics are concerned with different aspects of nature, they both share the same goal of understanding it and have a symbiotic relationship. The former provides data abo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quantum Computing
Quantum computing is a type of computation whose operations can harness the phenomena of quantum mechanics, such as superposition, interference, and entanglement. Devices that perform quantum computations are known as quantum computers. Though current quantum computers may be too small to outperform usual (classical) computers for practical applications, larger realizations are believed to be capable of solving certain computational problems, such as integer factorization (which underlies RSA encryption), substantially faster than classical computers. The study of quantum computing is a subfield of quantum information science. There are several models of quantum computation with the most widely used being quantum circuits. Other models include the quantum Turing machine, quantum annealing, and adiabatic quantum computation. Most models are based on the quantum bit, or "qubit", which is somewhat analogous to the bit in classical computation. A qubit can be in a 1 or 0 quantum s ...

Lindau Nobel Laureate Meetings
The Lindau Nobel Laureate Meetings are annual scientific conferences held in Lindau, Bavaria, Germany, since 1951. Their aim is to bring together Nobel laureates and young scientists to foster scientific exchange between different generations, cultures and disciplines. The meetings assume a unique position amongst international scientific conferences, as from 30 to 65 Nobel laureates attending each edition they are the largest regular congregation of Nobel laureates in the world, apart from the Nobel Prize award ceremony in Stockholm. Purpose Every Lindau Meeting consists of a multitude of scientific sessions like plenary lectures and panel discussions as well as a variety of networking and social events. The meetings are not centered on the presentation of research results, but instead, their main goals are the exchange of ideas and the discussion of topics globally relevant to all scientists. The Nobel laureates do not receive any kind of payment for their participation and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
