A team of researchers from Harvard University and Massachusetts Institute of Technology has found that they could use an optical tweezer array of laser-cooled molecules to observe ground state collisions between individual ...
A team of researchers from Xiamen University, the University of Ottawa and the University of Rochester has shown that it is possible to entangle photons with correlations between their radial and momentum states. In their ...
Dead or alive, left-spinning or right-spinning—in the quantum world particles such as the famous analogy of Schrödinger's cat can be all these things at the same time. An international team, including researchers from ...
