Abstract

This paper presents an overview of quantum errors and noise channels, their mathematical modeling and its implementation in quantum one time password (QOTP) based user authentication. Quantum noise plays a pivotal role in understanding quantum information theory which is important to build up quantum communication theory. The Kraus operators provide a powerful mathematical tool in understanding and modeling various quantum channels. Use of QOTP provides an impressive method of carrying out user authentication involving quantum operations based on user biometrics. However, the efficiency of this method can be better envisaged by incorporating noise models during qubit transmission.

Two‐factor authentication using biometric based quantum operations

Mohak Dwarkadhish Sharma, Manisha J. Nene

Abstract Two‐way authentication methods are utilized in every online user authentication transactions. Use of one time passwords (OTP) have proved to be more secure method, than one factor authentication when the two authentication schemes are carried out on different media. However, current use of OTP restricts authentication to the device itself rather than the user. The fraud cases with OTP based transactions have also increased due to growth of technology. Hence, there is a requirement of enhancing security of OTP based transactions. The study in this paper anchors on mathematically proven properties of quantum cryptography and utilizes the quantum entanglement property to generate quantum OTP (QOTP) for authenticating the user based on its biometrics. The proposed method takes into consideration various quantum computing capabilities of user, thus paving path for gradual upgradation of infrastructure. The work in the paper gives the outline of infrastructure required for implementing the proposed model and concludes by comparing security analysis of existing and proposed model against man‐in‐the‐middle attack (MITM) and user end vulnerabilities to bring forth the importance of QOTP. The practical implementation of the proposed model is envisaged as future research work due to evolving nature of quantum experiments.

Dual factor third‐party biometric‐based authentication scheme using quantum one time passwords†

Mohit Kumar Sharma, Manisha J. Nene

Abstract One Time Passwords (OTP) are being widely used for authentication of user to access a number of services offered online. The security vulnerabilities in classical execution of OTP schemes are addressed using Quantum OTP (QOTP) scheme with user biometrics. This scheme requires sharing of user biometric data with every service provider. The chances of leakage of user biometrics increase with increase in number of entities holding the data. Further, loss of data by any entity compromises user identity for all other services. The work carried out in this article addresses the above‐mentioned challenges by incorporating a trusted third party which holds user biometric data and carries out authentication on its behalf. The proposed model continues leveraging upon inherent security benefits provided by Quantum Entanglement and Quantum Communication and utilizing user biometrics as authentication data. It modifies the QOTP scheme by carrying out mutual authentication for user and server against a particular transaction. The proposed model brings in the advantages of Single Sign On facility in terms of hardware to reduce infrastructure cost and No Secret Sharing of user biometric data with the servers to protect against rogue servers. The security analysis demonstrates the merit of the inherent procedures of the proposed work which leverage on the no‐cloning and quantum cryptography principles.

Hybrid Quantum Noise Model to Compute Gaussian Quantum Channel Capacity

Mouli Chakraborty, Anshu Mukherjee, Avishek Nag +1 more

Quantum information processing leverages the principles of quantum mechanics, utilizing qubits, to improve computational and communicative tasks. In this realm, the quantum channel’s capacity is pivotal in determining the efficiency and accuracy of quantum information handling, with its performance being significantly influenced by channel noise. Our study aims to establish a holistic hybrid quantum noise model to determine the quantum channel capacity. In this paper, we formulated a mathematical expression for this capacity and conducted simulations for both Gaussian and non-Gaussian inputs. A hybrid noise model is constructed by convolution of Poisson-distributed quantum noise with classical additive white Gaussian noise. We characterized the quantum-classical noise and the received signal using Gaussian Mixture Models. The maximum amount of quantum information that can be reliably transmitted over a quantum channel (per use of the channel) is determined by its capacity, and entropy and related quantities like mutual information play a role in calculating this capacity. Our formulation of quantum channel capacity is derived from the mutual information shared between the transmitter and receiver, encompassing the entropies of the signals. The quantum channel presents a higher capacity-to-signal-to-noise ratio for Gaussian inputs than non-Gaussian ones.

Implementing Noise-Resilient Quantum Encryption with Hybrid Feedback and Non-Markovian Effects

Lokesh B S, Narasimha Kaulgud

Quantum One-Time Pad (QOTP) offers information-theoretic security but its realization on Noisy Intermediate-Scale Quantum (NISQ) devices is challenged by decoherence and hardware imperfections. This work presents a noise-aware QOTP framework that integrates adaptive error mitigation, lightweight 3-qubit repetition coding, and hybrid quantum-classical feedback. The methodology incorporates assumptions such as ideal Pauli gates and i.i.d. noise, and validates feasibility through Qiskit Aer simulations with 1024 shots. Results show that QBER is reduced from$0.21 \pm 0.02$to$0.13 \pm 0.01$under$30\%$depolarizing noise, demonstrating improved robustness without requiring full quantum error correction. While non-Markovian modeling is introduced conceptually, simulations primarily evaluate Markovian noise scenarios. The findings indicate that adaptive, lightweight strategies can enhance QOTP feasibility on current quantum hardware, although scalability to larger systems remains an open challenge.

Quantum channels and memory effects

Filippo Caruso, Vittorio Giovannetti, Cosmo Lupo +1 more

Any physical process can be represented as a quantum channel mapping an initial state to a final state. Hence it can be characterized from the point of view of communication theory, i.e., in terms of its ability to transfer information. Quantum information provides a theoretical framework and the proper mathematical tools to accomplish this. In this context the notion of codes and communication capacities have been introduced by generalizing them from the classical Shannon theory of information transmission and error correction. The underlying assumption of this approach is to consider the channel not as acting on a single system, but on sequences of systems, which, when properly initialized allow one to overcome the noisy effects induced by the physical process under consideration. While most of the work produced so far has been focused on the case in which a given channel transformation acts identically and independently on the various elements of the sequence (memoryless configuration in jargon), correlated error models appear to be a more realistic way to approach the problem. A slightly different, yet conceptually related, notion of correlated errors applies to a single quantum system which evolves continuously in time under the influence of an external disturbance which acts on it in a non-Markovian fashion. This leads to the study of memory effects in quantum channels: a fertile ground where interesting novel phenomena emerge at the intersection of quantum information theory and other branches of physics. A survey is taken of the field of quantum channels theory while also embracing these specific and complex settings.

Quantum Identity Authentication Protocol Based on Three-Photon Quantum Error Avoidance Code

Zhiguo Qu, Xinzhu Liu, Shengyao Wu

Quantum identity authentication is one of important techniques in quantum secure communications. So far, most of the quantum identity authentication protocols proposed are based on noise-free environments. However, due to the existence of quantum noise in quantum channels is inevitable, the noise immunity is very important to quantum identity authentication. In this paper, a novel quantum identity authentication protocol based on three-photon error avoidance code is proposed. In this protocol, quantum information is encoded on the noiseless subsystem, so the protocol can effectively resist on the interference of noise in the quantum channel to information transmission. And the comprehensive analysis of antinoise performance and the security analysis on various eavesdropping attacks shows that the new protocol proposed in this paper has not only good anti-noise performance, but also good security.
