“…This is so despite the fact that direct, magnetometric measurements of the spin via its magnetic moment have, after many years of effort [32], so far failed to achieve anything close to single-spin sensitivity; it is for this reason that we are pessimistic about a magnetic-force-microscope based quantum computer [33]. We feel that a very promising general strategy involves first converting the spin degree of freedom of the electron, which is very hard to measure, into a charge degree of freedom, which is measurable at the single-electron level by well-established electrometric techniques.…”

Abstract. 1 In this chapter we explore the connection between mesoscopic physics and quantum computing. After giving a bibliography providing a general introduction to the subject of quantum information processing, we review the various approaches that are being considered for the experimental implementation of quantum computing and quantum communication in atomic physics, quantum optics, nuclear magnetic resonance, superconductivity, and, especially, normal-electron solid state physics. We discuss five criteria for the realization of a quantum computer and consider the implications that these criteria have for quantum computation using the spin states of single-electron quantum dots. Finally, we consider the transport of quantum information via the motion of individual electrons in mesoscopic structures; specific transport and noise measurements in coupled quantum dot geometries for detecting and characterizing electron-state entanglement are analyzed. Brief Survey of the History of Quantum ComputingThe story of why quantum computing and quantum communication are theoretically interesting and important has been told in innumerable places before, and we will just point the reader to some of those. The "prehistory" of quantum computing (up to 1994) consists of the tinkerings of a small number of visionaries on the question of how data could be processed if bits could be put into quantum superpositions of states.

“…Clearly then, nonlocal effects due to dipole couplings dominate over the applied field gradient in this case. Similarly, Wago et al 8 found that imaging in YIG by standard means involving an applied field gradient was not successful. This contrasts with successful demonstrations of microscopic MRFM imaging by means of both electron spin resonance ͑ESR͒ and NMR.…”

Lateral one-dimensional imaging of cobalt ͑Co͒ films by means of microscopic ferromagnetic resonance ͑FMR͒ detected using the magnetic resonance force microscope ͑MRFM͒ is demonstrated. A novel approach involving scanning a localized magnetic probe is shown to enable FMR imaging in spite of the broad resonance linewidth. We introduce a spatially selective local field by means of a small, magnetically polarized spherical crystallite of yttrium iron garnet ͑YIG͒. Using MRFM-detected FMR signals from a sample consisting of two Co films, we can resolve the ϳ20 m lateral separation between the films. The results can be qualitatively understood by consideration of the calculated spatial profiles of the magnetic field generated by the YIG sphere.

“…115 The promise of spectroscopic measurements continued with a demonstration of MRFM-detected nutation and spin echoes. 116 Nutation spectroscopy was extended to quadrupolar nuclei in an experiment detecting NMR from five nuclei using MRFM ͑ 23 Na, 69 Ga, 71 Ga, 27 Al, and 51 V͒. 117 More recently, MRFM has been used to carry out spin echo spectroscopy 118 and observe dipolar spin echoes 119 in solids.…”

The invention and initial demonstration of magnetic resonance force microscopy (MRFM) in the early 1990s launched a renaissance of mechanical approaches to detecting magnetic resonance. This article reviews progress made in MRFM in the last decade, including the demonstration of scanned probe detection of magnetic resonance (electron spin resonance, ferromagnetic resonance, and nuclear magnetic resonance) and the mechanical detection of electron spin resonance from a single spin. Force and force-gradient approaches to mechanical detection are reviewed and recent related work using attonewton sensitivity cantilevers to probe minute fluctuating electric fields near surfaces is discussed. Given recent progress, pushing MRFM to single proton sensitivity remains an exciting possibility. We will survey some practical and fundamental issues that must be resolved to meet this challenge.
