NMR Quantum Computation with a hyperpolarized nuclear spin bulk
We consider two new quantum gate mechanisms based on nuclear spins in hyperpolarized solid Xe and HCl mixtures and inorganic semiconductors. We propose two schemes for implementing a controlled NOT ( CNOT ) gate based on nuclear magnetic resonance ( NMR ) spectroscopy and magnetic resonance imaging ( MRI ) from hyperpolarized solid Xe and HCl mixtures and optically pumped NMR in semiconductors....
متن کاملUnderstanding brute force
. A properly designed 2-dimensional parallel computer of size n can do both jobs in time n. A serial computer for either problem is much, much, much slower and can’t be much smaller: it needs n serial accesses to n bits of memory. A related myth is that analyzing the time of a computation on a huge serial computer is equivalent to analyzing the price and performance of parallel versions of the ...
متن کاملA Fuzzy Brute Force Matching Method for Binary Image Features
Matching of binary image features is an important step in many different computer vision applications. Conventionally, an arbitrary threshold is used to identify a correct match from incorrect matches using Hamming distance which may improve or degrade the matching results for different input images. This is mainly due to the image content which is affected by the scene, lighting and imaging co...
متن کاملHyperpolarized long-lived nuclear spin states in monodeuterated methyl groups.
Monodeuterated methyl groups may support a long-lived nuclear spin state, with a relaxation time exceeding the conventional spin-lattice relaxation time T1. Dissolution-DNP (dynamic nuclear polarization) may be used to hyperpolarize such a long-lived spin state. This is demonstrated for the CH2D groups of a piperidine derivative. The polarized sample is manipulated in the ambient magnetic field...
متن کاملNuclear spin noise imaging.
NMR images were obtained from the proton spin noise signals of a water-containing phantom, which was placed in the highly tuned, low-noise resonant circuit of a cryogenically cooled NMR probe in the presence of systematically varied magnetic field gradients. The spatially resolved proton spin density was obtained from the raw signal by a modified projection-reconstruction protocol. Although spi...
