"strontium or other charged atoms manipulated by EM/ lasers for calculations have difficulty scaling: space constraints, routing complexity... supports several hundred qubits on single chip... optical fibers attached to waveguides split/ rearranged in overlapping tapestry-like patterns so light reaches correct trapping zones... individual beams can be toggled on/ off without affecting others... 2 patterning methods, bubble sort/ blockwise duplication, minimizing power loss depending on specific needs of chip"
