The quantum database stores binary data in quantum qubits, and operations like storing, retrieving, and updating data can be performed using basic quantum gates. This is a basic prototype to showcase how can it be integrated into data storage and retrieval systems.","language":"Python","stars":17,"topics":["database","quantum","quantum-computing"],"license":null,"category":"databases-storage","readme_excerpt":"Quantum Database System (qndb) Contributing Welcome This is an active, open-source project. We welcome contributions from quantum computing enthusiasts, database engineers, and anyone interested in the intersection of quantum computation and data management. --- What is qndb? qndb is a quantum-native database engine built on top of Google Cirq. Unlike classical databases that store data in rows and columns on disk, qndb encodes data directly into quantum states — superpositions, amplitudes, and entangled registers — and leverages quantum algorithms to perform database operations with provable computational speedup. The system spans the full database stack : from low-level qubit encoding and error-corrected storage, through query parsing and optimization, all the way up to distributed consensus, enterprise analytics, and fault-tolerant operations on logical qubits protected by surface codes. Why a Quantum Database? Classical Database Quantum Database (qndb) --- --- Search: O(N) linear scan Search: O(√N) via Grover's algorithm Joins: O(N·M) nested loop Joins: O(√(N·M)) via quantum walk Optimization: heuristic query plans Optimization: QAOA/VQE for optimal plans Security: RSA/AES (quantum-vulnerable) Security: QKD + lattice-based (quantum-safe) Error handling: checksums, RAID Error handling: surface codes, logical qubits --- Table of Contents - What is qndb? - Installation - Quick Start - System Architecture - Core Modules Deep Dive - Quantum Engine - Encoding - Operations - Sto","default_branch":null,"files":null,"tree":[],"storefront":"/r/abhishekpanthee","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/abhishekpanthee/quantum-database/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
