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.

Download or read book Robust Quantum Logic in Neutral Atoms Via Adiabatic Rydberg Dressing written by and published by . This book was released on 2015 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: We study a scheme for implementing a controlled-Z (CZ) gate between two neutral-atom qubits based on the Rydberg blockade mechanism in a manner that is robust to errors caused by atomic motion. By employing adiabatic dressing of the ground electronic state, we can protect the gate from decoherence due to random phase errors that typically arise because of atomic thermal motion. In addition, the adiabatic protocol allows for a Doppler-free configuration that involves counterpropagating lasers in a [sigma]+/[sigma]- orthogonal polarization geometry that further reduces motional errors due to Doppler shifts. The residual motional error is dominated by dipole-dipole forces acting on doubly-excited Rydberg atoms when the blockade is imperfect. As a result, for reasonable parameters, with qubits encoded into the clock states of 133Cs, we predict that our protocol could produce a CZ gate in

Book excerpt: Abstract: In this work we present the results of studies of one-dimensional (1D) and two-dimensional (2D) optical lattices on a chip. We have developed a method to create 1D and 2D optical lattices above an optical waveguide. The method is based on the destructive interference of the evanescent waves of two modes of the waveguide, resulting in a periodic array of nodes above the waveguide surface. For blue-detuned light, this constitutes an array of optical dipole traps for neutral atoms. One pair of modes coupled into a ridge waveguide creates a 1D array of nodes in this manner, and two orthogonal pairs of modes in a slab waveguide result in a 2D array of nodes. Computational analysis of our method showed that these optical atom chips may be suitable for use as a quantum register, and for studies of atom-surface interactions between the trapped atoms and the waveguide surface. Using realistic waveguide materials and laboratory laser parameters we found that for a laser power of [approx.]100 mW nodes can be created [approx.]100 nm above the waveguide surface. The nodes constitute atom traps that are [approx.]1mK deep, and have trap frequencies [approx.]1MHz and ground state sizes of [approx.]10 nm. The spacing between traps is [approx.]1 um enabling individual addressing with a focused laser beam. With the implementation of two-qubit gates in mind, initial investigations of extensions of the basic 2D optical lattice were conducted. Computational results for a counter-propagating 2D optical lattice with very close trap spacing ([approx.][lambda]/4) in one dimension, and for a 2D optical lattice with adjustable spacing between pairs of traps in one dimension are presented. An experimental setup for the realization of the proposed 2D optical lattices on a chip was designed and built. Several cooling and trapping steps necessary to prepare a cold atom sample for loading of the 2D optical lattice have been implemented successfully. In the course of previous studies of atom-surface interactions, a novel surface-ionization detector for 2D imaging of neutral atom samples was built and characterized. We find a detection efficiency [approx.]50 %, a spatial resolution of 20 um and a time response
