Trapped ions are excellent candidates for quantum computing and quantum networks because of their long coherence times. ability to generate entangled photons as well as high fidelity single- and two-qubit gates. To scale up trapped ion quantum computing. we need a Bell-state analyzer on a reconfigurable platform that can herald high fidelity entanglement between ions. https://www.roneverhart.com/Clear-Zig-Zag-Pet-Gate/
