Abstract: Millicharge particles with charge just evading accelerator bounds, possess charge large enough to accumulate on earth and cause gigantic build-up over the age of the earth. I introduce a new idea that sets exquisite bounds on millicharge particle dark matter and promises to reach interesting parameter space in the near future. The new detection concept involves the remarkable sensitivity of standard model ions trapped in E&M fields which are being developed for quantum computing. If time permits another exotic signature; dark matter - standard model bound states mediated by a heavy dark photon will also be presented.
