As compared to lots delivered in our previous trap fabs 2. Including two quantum computer generations (256 - qubit and 10K), quantum networking devices, and low - SWaP optical control technology Footnote 2: For visibility, this is how I am counting it: 1. 256 trap devices; 2. 10k trap devices; 3. Low-loss, wideband SiN photonic integrated circuits (PICs); 4. Ultra-high efficiency fiber-to-chip optical couplers; 5.
