Patent of the Month: July 2020

Patent of the Month logo with the title of the patent of the month, Fast Entangled State Generation and Quantum Information Transfer in Quantum Systems with Long-Range Interactions, patent number 10,432,320

Technology Description

NIST has created a method to use quantum systems with long-range interactions to do the following two things faster (in some cases exponentially faster) than in systems with short-range interactions: (1) accomplish quantum state transfer across the system; (2) prepare a large variety of entangled states with applications to metrology and quantum computing.  This method makes use of individual control of all participating quantum bits and takes advantage of long-range interactions in such a way that many interaction pathways coherently and constructively interfere to provide the speed-up.
