Book Synopsis Quantum Sensing Experiments with Superconducting Qubits by : Schneider, Andre
Download or read book Quantum Sensing Experiments with Superconducting Qubits written by Schneider, Andre and published by KIT Scientific Publishing. This book was released on 2021-06-04 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quantum sensing is a vast and emerging field enabling in-situ studies of quantum systems and hence the development of quantum hybrid systems. This work creates the fundament of direct superconducting-magnetic hybrid systems by developing a local microwave sensing scheme and studying the influence of a static magnetic field on a superconducting qubit. Finally, a proof-of-principle hybrid system is demonstrated, which opens the path towards superconducting-magnetic quantum circuits.

Book excerpt: Complementary to scattering techniques, scanning tunnelling microscopy provides atomic-scale real space information about a material's electronic state of matter. State-of-the-art designs of a scanning tunnelling microscope (STM) allow measurements at millikelvin temperatures with unprecedented energy resolution. Therefore, this instrument excels in probing the superconducting state at low temperatures and especially its local quasiparticle excitations as well as bosonic degrees of freedom.
Book Synopsis Quantum Tunneling of Josephson Vortices in High-Impedance Long Junctions by : Wildermuth, Matthias Micha
Download or read book Quantum Tunneling of Josephson Vortices in High-Impedance Long Junctions written by Wildermuth, Matthias Micha and published by KIT Scientific Publishing. This book was released on 2023-09-11 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last decades, superconducting devices have emerged as a promising platform for quantum technologies, including quantum sensing and quantum computing. Their key elements are Josephson junctions, which allow for coherent supercurrent tunneling between two weakly linked superconductors. If such a junction is extended in one direction to a long junction, the superconducting phase difference can vary in space and time and may allow for quantized phase windings that drive supercurrent vortices.
Book Synopsis Molecular Motor Based on Single Chiral Tripodal Molecules Studied with STM by : Skolaut, Julian
Download or read book Molecular Motor Based on Single Chiral Tripodal Molecules Studied with STM written by Skolaut, Julian and published by KIT Scientific Publishing. This book was released on 2023-09-14 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work presents a single molecular motor driven by the current in an STM. Its chiral functional group is supposed to perform a rotation in a preferred direction, proven by Binomial tests to be statistically significant. The rotation is proposedly driven by the chiral-induced spin selectivity effect (CISS). However, the studies of the rotation on the dependence on the lateral tip position, voltage and current indicate that he CISS is unlikely to cause the preferred rotation direction.

Book Synopsis Quantum Computing by : National Academies of Sciences, Engineering, and Medicine
Download or read book Quantum Computing written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2019-04-27 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quantum mechanics, the subfield of physics that describes the behavior of very small (quantum) particles, provides the basis for a new paradigm of computing. First proposed in the 1980s as a way to improve computational modeling of quantum systems, the field of quantum computing has recently garnered significant attention due to progress in building small-scale devices. However, significant technical advances will be required before a large-scale, practical quantum computer can be achieved. Quantum Computing: Progress and Prospects provides an introduction to the field, including the unique characteristics and constraints of the technology, and assesses the feasibility and implications of creating a functional quantum computer capable of addressing real-world problems. This report considers hardware and software requirements, quantum algorithms, drivers of advances in quantum computing and quantum devices, benchmarks associated with relevant use cases, the time and resources required, and how to assess the probability of success.
Book Synopsis Towards a Spin-Ensemble Quantum Memory for Superconducting Qubits by : Cécile Grèzes
Download or read book Towards a Spin-Ensemble Quantum Memory for Superconducting Qubits written by Cécile Grèzes and published by Springer. This book was released on 2015-08-19 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work describes theoretical and experimental advances towards the realization of a hybrid quantum processor in which the collective degrees of freedom of an ensemble of spins in a crystal are used as a multi-qubit register for superconducting qubits. A memory protocol made of write, read and reset operations is first presented, followed by the demonstration of building blocks of its implementation with NV center spins in diamond. Qubit states are written by resonant absorption of a microwave photon in the spin ensemble and read out of the memory on-demand by applying Hahn echo refocusing techniques to the spins. The reset step is implemented in between two successive write-read sequences using optical repumping of the spins.

Book Synopsis Quantum Machines: Measurement and Control of Engineered Quantum Systems by : Michel Devoret
Download or read book Quantum Machines: Measurement and Control of Engineered Quantum Systems written by Michel Devoret and published by OUP Oxford. This book was released on 2014-06-12 with total page 601 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gathers the lecture notes of courses given at the 2011 summer school in theoretical physics in Les Houches, France, Session XCVI. What is a quantum machine? Can we say that lasers and transistors are quantum machines? After all, physicists advertise these devices as the two main spin-offs of the understanding of quantum mechanical phenomena. However, while quantum mechanics must be used to predict the wavelength of a laser and the operation voltage of a transistor, it does not intervene at the level of the signals processed by these systems. Signals involve macroscopic collective variables like voltages and currents in a circuit or the amplitude of the oscillating electric field in an electromagnetic cavity resonator. In a true quantum machine, the signal collective variables, which both inform the outside on the state of the machine and receive controlling instructions, must themselves be treated as quantum operators, just as the position of the electron in a hydrogen atom. Quantum superconducting circuits, quantum dots, and quantum nanomechanical resonators satisfy the definition of quantum machines. These mesoscopic systems exhibit a few collective dynamical variables, whose fluctuations are well in the quantum regime and whose measurement is essentially limited in precision by the Heisenberg uncertainty principle. Other engineered quantum systems based on natural, rather than artificial degrees of freedom can also qualify as quantum machines: trapped ions, single Rydberg atoms in superconducting cavities, and lattices of ultracold atoms. This book provides the basic knowledge needed to understand and investigate the physics of these novel systems.
