Quantum computing is attracting great interest due to its potential for solving computationally hard problems. The QRydDemo project aims to build a quantum computer based on neutral strontium atoms individually trapped in an optical tweezer array. We will study a so far unexplored qubit encoded in the 3P0 and 3P2 fine-structure states of Strontium. This qubit provides "triple magic trapping" and the potential to improve the coherence time by a factor of 1000 from previous demonstrations of 10 microseconds to 10 milliseconds. We will combine this qubit with a novel tweezer architecture which allows for reshuffling of the qubits during the quantum computation. Such a dynamically adjustable qubit array allows for new algorithmic possibilities by effectively increasing the connectivity for deep quantum circuits to solve real-world problems. We plan to offer access to the hardware through a currently developed compiler software stack via our website www.thequantumlaend.de.
