in Danish Resumé på dansk Overordnet handler denne bacheloropgave om hvorledes kvantetilstanden for en lyspuls kan gemmes i, og senere udlæses fra, en gas af atomer, hvorved sidstnævnte fungerer som en kvantehukommelse. Dette hører ind under feltet kvanteoptik, som netop beskæftiger sig med lysets kvanteegenskaber, som de manifesterer sig i vekselvirkningen med atomer. Kvantehukommelse udgør en...

Background: The effect of Dps-DNA co-crystals formation, which occurs in stressed Escherichia coli cells exposed to extreme conditions, is well described the literature. However, exact mechanisms formation are yet be postulated remaining largely unknown. Here we summarize results obtained by our group over last few years using cryo-Electron Microscopy (cryo-EM) and Small Angle X-ray Scattering ...

Quantum computers operate with qubits, which are entities that can be in the state |0〉, state |1〉 or any superposition (linear combination) of those. One of the essential parts of a quantum computer is a controlled two-qubit gate. An example of such gate is the controlled phase gate, which imparts a phase of π (i.e. multiplies by −1) to the state, where both qubits are in |1〉. In this thesis we...

+MacLeod, T D; Snyder-Mackler, L; Axe, M J; Buchanan, T S + Center for Biomedical Engineering Research, University of Delaware, DE [email protected] ABSTRACT INTRODUCTION: Anterior cruciate ligament (ACL) reconstruction is commonly performed with a cadaveric allograft (ALLO) or a hamstring semitendinosus-gracilis (STG) autograft. Knee flexor strength deficits following STG reconstruction are a g...

This thesis concerns methods for developing control software for autonomous systems with a high level of modularity, striving towards a declarative control paradigm, where the control system is able to solve control and estimations tasks based on system and objective descriptions alone. This is pursued on the basis of Quantised State Systems (QSS) which is a recent formalism for working with sy...

We fabricate graphene-TiOx-Al tunnel junctions and characterize their radio frequency response. Below the superconducting critical temperature of Al and when biased within the superconducting gap, the devices show enhanced dynamic resistance which increases with decreasing temperature. Application of radio frequency radiation affects the dynamic resistance through electronic heating. The relati...
