An Apparatus for Controlling the Sr Clock Qubit

Arrays of optical tweezers loaded with neutral atoms have rapidly gained traction as a versatile and scalable architecture for quantum information processing. At Eindhoven University of Technology, we are developing a tweezer apparatus that allows control over single- and multi-qubit gates using the Sr clock qubit. <br/><br/>On the poster, we will present our recent experimental results of preparing single Sr atoms in our array of 5 x 5 optical tweezers. Spectroscopy measurements reveal an average tweezer depth of 0.51(2) mK and a standard deviation across of the array in the depth of 2.8%. Also shown are our first steps towards our two goals, which are site-resolved single-qubit operations using the ultranarrow 1S₀–3P₀ clock transition and implementing multi-qubit entangling gates via coherent excitation to Rydberg states using an ultraviolet laser. <br/><br/>Looking ahead, we aim to make this platform remotely accessible through the open platform Quantum Inspire, opening the door for broader experimentation and algorithm development within the community.<br/>
