A Quantum Variational Approach to Prototypical Recurrent Unit

Summary

Researchers introduce QPRU, a lightweight quantum recurrent architecture that keeps forecasting performance on par with state-of-the-art classical and quantum baselines while using far fewer trainable parameters, offering a more scalable and parameter-efficient alternative to models such as LSTM, GRU, QLSTM, and QGRU.

Abstract:We introduce a lightweight Quantum Prototypical Recurrent Unit (QPRU) that requires significantly fewer parameters than both classical recurrent architectures, such as Long Short- Term Memory (LSTM) and Gated Recurrent Unit (GRU), and quantum variants, including Quantum LSTM (QLSTM) and Quantum GRU (QGRU). Despite its compact design, the QPRU achieves competitive forecasting performance, matching state-of-the-art baselines while offering important structural and practical advantages, including enhanced scalability and a reduced number of trainable parameters.
