A year earlier, he and Ph.D. student Bin Gui G»14 determined
the quantum numbers of the first neutral, heavy tetraquark candidate, X (3872).
«Even though all four particles contain the same quark composition, each
of them has a unique internal structure, mass and set
of quantum numbers,» says Skwarnicki, who, in April 2014, confirmed the existence
of the world's
first charged tetraquark candidate, called Z (4430) +.
«New chip could bring highest level
of encryption to any mobile device:
First use
of quantum technology to create a random
number generator that is both tiny and fast.»
