PlankDB – A Quantum-Powered Key-Value Store with Grover (Spring Boot)

Hi HN!

We’ve built *PlankDB*, an experimental key-value database that supports quantum-powered search via Grover's algorithm.

It combines: - Quantum search using IBM Qiskit (Grover's Algorithm) - Java 17 + Spring Boot + Clean Architecture - RESTful API with Swagger - Support for local (simulated) and IBM remote quantum execution

The quantum part isn't just a gimmick — it performs a *probabilistic search* over inserted keys using Grover’s quadratic speedup. We also support classical search for comparison.

The project is fully open-source and actively maintained: https://github.com/swampus/plank-db

Would love your feedback — ideas, bugs, or quantum jokes are all welcome!
