Outline

This paper presents a quantum cardinality estimation (QCardEst) technique using quantum machine learning and hybrid quantum-classical networks. It encodes SQL queries into a compact quantum state that requires only the number of qubits equal to the number of tables contained in the query, enabling the entire query to be processed by a single variational quantum circuit (VQC) on current hardware. Furthermore, we compare several classical postprocessing layers to convert the probability vector output of VQC into a cardinality value, and introduce quantum cardinality correction (QCardCorr), which multiplies the coefficients generated by VQC to improve the classical cardinality estimator. Using QCardCorr, we achieve a 6.37x performance improvement over the standard PostgreSQL optimizer on JOB-light, an 8.66x improvement on STATS, and a 3.47x improvement over MSCN on JOB-light.

Takeaways, Limitations

•

Takeaways:

◦

We demonstrate that quantum computing can be used to improve the performance of cardinality estimation, a crucial part of database query optimization.

◦

The proposed QCardEst and QCardCorr techniques provide superior performance over existing classical methods.

◦

This suggests that it is possible to design quantum algorithms that operate efficiently even on current quantum computer hardware with a limited number of qubits.

•

Limitations:

◦

The experimental results are limited to specific datasets (JOB-light, STATS), requiring further research on generalizability.

◦

Further validation is needed to verify the scalability of the proposed method and its applicability to various types of SQL queries.

◦

As quantum computing hardware advances, there is room for performance improvements and algorithmic improvements.
