Scalable Architecture for Universal Quantum Computing
Dr. Amit BEN KISH, CTO & Co-founder Quantum Art
Abstract
Quantum computation is at an inflection point. As these processors grow in scale and reliability, the need for efficient decomposition of large circuits, becomes critical.
Trapped ions-based systems form a successful platform for quantum computing, due to their high fidelity, all-to-all connectivity, and local control. However, scalability to very large qubit numbers and gate count is still a challenge. Here, we propose and demonstrate the building blocks of a holistic, scalable architecture for quantum computing.
Quantum Art’s approach [1] is centered around 4 core technological pillars: multi-qubit gates [2] capable of executing the equivalent of up to 1,000 2-qubit operations in a single step; optical segmentation into independently operating cores using laser-defined optical potentials; dynamic reconfiguration of multi-core arrays for rapid entanglement distribution; and modular, high-density 2D structures within compact footprints. This result in systems with up to x100 more gates per second, x100 more parallel operations, and a footprint up to x50 smaller. Together with our proprietary compiler [3], these technologies enable high-speed, robust execution across large-scale systems, advantageous both for fault-tolerant digital quantum computation and analog quantum simulations.
