Researchers restore the quantum state after initial measurement wipes it out.

A newly published study looks at recent advances in quantum measurements, coherent control, and the generation of entangled states, while describing some of the challenges that remain ahead for quantum computing and other applications.

===> In quantum-based sys­tems, the direc­tion of the spin (either up or down) serves as the basic unit of infor­ma­tion, which is anal­o­gous to the 0 or 1 bit in a clas­si­cal com­put­ing sys­tem. Unlike our clas­si­cal world, an elec­tron spin can assume both a 0 and 1 at the same time, a feat called entan­gle­ment, which greatly enhances the abil­ity to do computations. <===
