Tomographic Reconstruction Apparatus and Removing Diffraction Effects in a Tomographic Image

NIST Inventors

Zachary H. Levine

The invention is a method for creating improved tomographic reconstructions in the presence of diffraction. The new feature is the recognition that it is possible to make an iterative method which has the same scaling in computation time as projective tomography.

Nearly Optimal Time-Independent Reversal of a Spin Chain

NIST Inventors

Alexey Gorshkov

This technology is a time-independent protocol that reverses the order of qubits in a chain (e.g., changing the order $1, 2, 3$ to $3, 2, 1$). It uses a pre-engineered "Hamiltonian"—a specific set of fixed magnetic fields and interactions between neighboring qubits—to naturally evolve the system
