The monitoring of physiological biomarkers is fundamental to the diagnosis and treatment of disease. We describe here the development of molecular sensors which can be read by magnetic resonance (MR) relaxometry. MR is an advantageous bio-sensor readout because it can be determined from opaque samples and through intervening layers of matter. Wash steps can therefore be avoided in in vitro MR a...

The application of nuclear magnetic resonance (NMR) imaging to a stereotactic method is described. The physical properties of NMR offer some important advantages such as good contrast between grey and white matter and the possibility to scan the brain in three planes and at any desired angle. Stereotactic localisation by NMR gives very satisfactory and precise visualisation of the target struct...

Nuclear Magnetic Resonance spectroscopy and imaging can be classified as inductive techniques working in the near- to far-field regimes. We investigate an alternative capacitive detection with the use of micrometer sized probes positioned at sub wavelength distances of the sample in order to characterize and model evanescent electromagnetic fields originating from NMR phenomenon. We report that...

We offer an improved method for using a nuclear-magnetic-resonance quantum computer (NMRQC) to solve the Deutsch-Jozsa problem. Two known obstacles to the application of the NMRQC are exponential diminishment of density-matrix elements with the number of bits, threatening weak signal levels, and the high cost of preparing a suitable starting state. A third obstacle is a heretofore unnoticed res...

Nuclear Magnetic Resonance (NMR) is a spectroscopic technique widely used by organic chemists. NMR provides details about the location, number and environment of specific types of atoms within a sample. The proper interpretation of this information allows detailed chemical structures to be discerned. The same basic instrumentation used in this week’s experiment is used in physician offices when...

Nuclear magnetic resonance or NMR is one of the most widely used discoveries of Modern Physics. NMR is based on the bulk magnetic properties of materials made up of certain isotopes, most notably, protons (1H), but encompassing a wide variety of species including C, F, and Si. NMR is used to measure magnetic fields with exquisite precision. NMR is used in chemical analysis, oil exploration, and...

Nuclear Magnetic Resonance (NMR) is arguably both the best and the worst technology we have for the implementation of small quantum computers. Its strengths lie in the ease with which arbitrary unitary transformations can be implemented, and the great experimental simplicity arising from the low energy scale and long time scale of radio frequency transitions; its weaknesses lie in the difficult...

Nuclear magnetic resonance (NMR) is typically thought of as a possible technology for quantum computation. Here we instead outline how commercially available NMR spectrometers could be used to perform non-quantum computation: from addressable 3D memory, to a programmable 3D reaction-diffusion computer.
