New method to understand superconductors: ...describe a new method to understand the cooling of atoms, which is to simulate a superconductor using a "quantum simulator" (a kind of bespoke quantum computer for examining specific problems) rather than a supercomputer.
The researchers found that just such a simulator can be built to examine atoms cooled to just a millionth of a degree above absolute zero. The atoms are controlled using laser beams which enhance the electrical forces between the atoms, which are usually weak and unimportant. These forces mimic the physics of the superconductor, and the proposed simulator includes far more physical detail than ever before.
