Turquoise clock-magic-wavelength tweezer arrays of fermionic strontium atoms for quantum metrology and computation

State-insensitive optical traps of neutral atoms offer a platform for precision quantum metrology and computing. These traps are created using magic wavelengths of light, which uniformly shift the energy levels of two atomic states throughout the trap and preserve the transition frequency. Trapping strontium atoms in an optical tweezer array at 497.0 nm, we measure this new theoretically predicted magic wavelength for the clock transition. This turquoise wavelength has five times the polarizability and allows smaller spot sizes than previously achieved. Our measurement also aids in the determination of excited state transition matrix elements and their effects on the clock transition. This new magic wavelength has facilitated our creation of more closely spaced 2D optical fermionic tweezer arrays loaded from a degenerate fermi gas, and it will enable new experiments with entangled tweezer clocks and quantum computing.
