Researchers have achieved a significant advance in the performance of neutral-atom quantum processors, overcoming one of the main limitations for their practical application: the low quantum circuit iteration rate (qCIR). They have demonstrated a high-throughput system that integrates a chip-based photonic interface with a 10-qubit array, achieving non-destructive readout and atom reuse.

This new approach allows for a retention probability of 99.7% after readout, which is crucial for maintaining qubit coherence. The system achieved a raw qCIR of 101 Hz and a post-selected qCIR of 74.8 Hz. These values represent a substantial improvement in the speed at which quantum circuits can be executed and repeated, a key factor for debugging, characterization, and the execution of complex algorithms.

Furthermore, the study verified a general throughput optimization methodology, obtaining a normalized Fisher information rate of 57.7 Hz. This represents an improvement of more than an order of magnitude in throughput compared to conventional methods. The ability to reuse atoms after non-destructive readout is a fundamental step towards more efficient and scalable quantum processors, opening a practical path for the development of high-performance neutral-atom quantum computers.
