Abstract

This proposal aims to push the boundaries of quantum computing by creating a unique 3D "cluster state" of neutral atoms, a form of quantum entanglement that, unlike traditional systems, is highly robust to noise and qubit loss. Cluster states provide unique ways to measure entanglement and could from the basis of future quantum computers. Using a computational imaging technique called point spread function (PSF) engineering, the researchers will significantly speed up the process of detecting the quantum states of atoms in a 3D array, allowing for the kind of faster measurements that are a prerequisite for quantum computing. This imaging system will use specially designed optical elements to capture data from all atoms in one shot, eliminating the need for slower, layer-by-layer imaging methods. The project is a collaboration between Penn State and the Technion, combining expertise in atomic physics and optical engineering. Beyond advancing quantum computing, this work has the potential to inspire innovations in 3D microscopy and atomic-scale imaging, with applications in diverse areas of science and technology. The proposers plan to create 3D cluster states in a 3D optical lattice of neutral atom qubits. This maximally entangled state has a range of dramatic features that will be studied, including: stabilizers that can be used to validate large entangled states (like the initial target 5×5×5 state) with very few measurements; extreme robustness to decoherence, incl
