Fundamentals of quantum computation and basic quantum gates
(IGI Global, 2024) Mummadi, S.; Rudra, B.
Quantum computing plays a major role in modern computation. It can perform operations exponentially faster when compared to classical computation. It has applications in various areas like secure communication, drug design, artificial intelligence, cyber security, etc. Thus, the researchers and students are showing interest to perform experiments in quantum computing to design novel architectures. But to learn/understand quantum computing, one should have strong knowledge of its basics. Because quantum computing performs operations at the atomic level, so the learners need to understand basic concepts like Qubits, superposition, quantum gates, etc. This chapter gives a clear idea about the basic concepts of quantum computing like Qubits, superposition, entanglement, and quantum gates.

Optimisation of quantum circuits using cost effective quantum gates
(Inderscience Publishers, 2025) Mummadi, S.; Rudra, B.
The importance of reversible operations has increased with the emergence of new technologies. Reversible operations are crucial for developing energy-efficient and cost-efficient circuits. The efficiency of a quantum circuit is measured in terms of quantum cost and quantum depth. In this paper, we propose an optimisation algorithm for reversible gates like the Peres gate, Toffoli gate, and the entanglement purification method. Peres and Toffoli gates play an important role in quantum circuit implementation, and entanglement purification plays a key role in various applications like quantum teleportation, secure communication, quantum key distribution, etc. The proposed algorithm optimises the quantum cost and quantum depth to 20% compared to the existing approaches. © 2025 Inderscience Enterprises Ltd.
Practical Demonstration of Quantum Key Distribution Protocol with Error Correction Mechanism
(Springer, 2023) Mummadi, S.; Rudra, B.
Quantum Key Distribution is a major building block of Quantum cryptography. A Quantum key is generated through the quantum particles. Quantum particles perform operations based on quantum mechanical principles like superposition and entanglement. With these principles, it is not possible for a third party to observe the quantum information. This proves that the Quantum key is highly secured and unbreakable compared to the current existing classical keys. But the major problem observed with quantum information is inbuilt noise which results in high error rates. To overcome this problem, we propose a Quantum key distribution protocol with entanglement purification and asymmetric quantum error correction. With the experiment, we have observed that the proposed method reduces the third-party quantum key detection probability and also increases the quantum key length and communication efficiency by reducing the error rate to 0.04%. © 2023, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.
Quantum Cost Optimization Algorithm for Entanglement-based Asymmetric Quantum Error Correction
(Springer, 2023) Mummadi, S.; Rudra, B.
The importance of reversible operations has been increasing day by day to overcome the drawbacks of irreversible computation. Quantum computers perform operations exponentially faster by taking advantage of reversible operations. Reversible operations play an essential role in developing energy and cost-efficient circuits. The efficiency of a quantum circuit is measured in terms of Quantum cost and Quantum depth. In this paper, we propose an optimization algorithm for Entanglement-based Quantum error correction, which plays a crucial role in various applications like quantum teleportation, secure communications, quantum key distribution, etc. We performed the experiments using Qiskit and RCViewer+ tools. Qiskit tool is used to run the quantum algorithms and measure the quantum depth; the RCViewer+ tool is used to measure the quantum cost. The proposed algorithm optimizes the quantum cost and depth compared to the existing approaches. © 2023, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.
