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

Photoacoustic Soot Measurement System for Cleaner Engines

NIST Inventors
Amy Mensch , Ryan Falkenstein-Smith and Thomas Cleary
This invention introduces a photoacoustic measurement system that detects soot deposition in engines. It works by irradiating soot deposits with pulsed electromagnetic radiation, causing rapid expansion that generates an acoustic pressure wave. The system then senses the pressure wave using an
