In the modern world, the financial sector faces a wide range of extraordinary events, from market shocks and geopolitical tensions to pandemics and cyberattacks. These diverse challenges significantly impact banks. Recently, particular attention has been drawn to the influence of artificial intelligence (AI) and quantum computing (QC) technologies on the stability of the financial system. This article analyzes the potential areas of impact of quantum technologies on the financial sphere in general and the resilience of financial institutions in particular.It's determined that quantum technologies can simultaneously pose both threats and new opportunities. Specifically, the article analyzes the potential of quantum technologies to break existing cryptographic algorithms that protect the confidential data of financial institutions' clients. This threat is exacerbated by the possibility of "harvest now, decrypt later" attacks, where malicious actors intercept data today with the intention of decrypting it in the future. This presents challenges and threats for online/mobile banking, payment operations, and corporate communications. Among the positive impacts of quantum technologies on banking, the article highlights improved financial risk assessment, particularly enhanced accuracy in stress testing, portfolio management, and derivatives pricing, by solving problems inaccessible to classical computing. The potential of quantum machine learning for fraud detection is also noted. Attention is given to the financial sector's response to these challenges. Initiatives for developing quantum-resistant (post-quantum) cryptography are considered as the primary method for mitigating the risks associated with the proliferation of quantum computing, along with new cryptographic protocols and quantum key distribution as a new opportunity to enhance security. The article emphasizes the responsibility of central banks in forming quantum-readiness strategies, including investments in post-quantum cryptography, expertise development, and the adaptation of regulatory frameworks. The conclusion drawn is that although the immediate benefits of quantum technologies may be modest, their long-term transformative potential for the financial sector is immense.

The advent of quantum technologies marks a transformative era for cybersecurity, with profound implications for the financial sector. Quantum computing, with its unparalleled computational power, poses both opportunities and challenges. On the one hand, quantum algorithms can optimize complex economic systems, enhance risk management, and improve data analysis. On the other hand, they threaten the security of traditional cryptographic protocols, potentially rendering current encryption methods obsolete. This study explores the dual-edged impact of quantum technologies on the financial sectors cybersecurity framework. It highlights the urgency for quantum-resistant cryptographic solutions and examines ongoing efforts to develop post-quantum cryptography. Furthermore, the paper discusses the potential for quantum key distribution (QKD) to revolutionize secure communication. By analyzing these developments, this research provides a roadmap for financial institutions to adapt and thrive in a quantum-enabled future while safeguarding critical assets and consumer trust.
Quantum computing has emerged as a transformative technology that holds the potential to revolutionize various industries, including banking. As quantum computers continue to advance, they pose significant risks to existing encryption methods that secure sensitive financial data. Traditional cryptographic systems, such as RSA and elliptic curve cryptography (ECC), are foundational to modern banking security; however, these methods rely on mathematical problems that quantum algorithms, notably Shor's Algorithm, could solve exponentially faster than classical computers. This paper explores the impact of quantum computing on banking encryption systems and discusses the urgent need for post-quantum cryptography. We examine the vulnerabilities of current banking encryption protocols, the status of quantum-safe cryptographic algorithms, and strategies for implementing quantum-resistant systems in the financial sector. The transition to post-quantum security requires collaborative efforts among financial institutions, regulatory bodies, and quantum computing researchers to ensure a secure and efficient implementation of future-proof encryption standards. This paper emphasizes the importance of early adoption and the proactive steps required to safeguard banking systems against the imminent quantum threat
The banking sector remains a high-value target for cyberattacks due to its vital role in managing sensitive financial data and enabling large-scale digital transactions. As digital banking expands, cyber risks increasingly carry systemic implications. In this context, quantum computing represents a fundamental shift in the cybersecurity landscape. Widely used encryption mechanisms such as RSA and elliptic curve cryptography (ECC), which underpin digital banking, payments, and data protection, are vulnerable to future quantum attacks particularly under the "harvest now, decrypt later" (HNDL) threat model, where encrypted financial data collected today may be compromised once quantum computing capabilities mature. This research examines the role of quantum computing in reshaping banking cybersecurity, with emphasis on post-quantum cryptography (PQC), quantum key distribution (QKD), quantum random number generation (QRNG), and quantum machine learning (QML) for fraud detection. Drawing on global and Indian banking practices, regulatory guidance from RBI and SEBI, and policy initiatives such as India's National Quantum Mission, the study proposes a structured roadmap for quantum readiness. The NIST finalization of PQC standards (FIPS 203–205, August 2024) has removed a key barrier to action, enabling banks to begin quantum-safe migration immediately. The study concludes that quantum-safe migration is a strategic imperative requiring phased implementation, architectural modernization, and coordinated regulatory and institutional action
The rise of quantum computing presents a profound shift in the cybersecurity landscape, particularly for the banking and finance sectors, where the protection of sensitive data is paramount. Traditional encryption methods are increasingly at risk of being compromised by the computational power of quantum machines, demanding the adoption of quantum-resistant technologies. This discussion delves into quantum key distribution (QKD) and post-quantum cryptographic algorithms, exploring their potential to secure financial transactions, protect customer information, and reinforce the integrity of banking networks. The application of these technologies offers new avenues for safeguarding data against quantum attacks while also addressing the challenges associated with integrating quantum security into existing infrastructures. The exploration also highlights the risks posed by quantum computers to current cryptographic systems and provides guidance on how financial institutions can transition to quantum-secure frameworks. By embracing these innovations, the banking and finance sectors can build resilience against future cyber threats in an era of quantum computing.
Abstract : The financial sector faces escalating cybersecurity threats, exacerbated by the potential emergence of quantum computers capable of compromising widely used classical cryptographic methods. The paper includes an AI-enhanced general review on the use of quantum cryptography to secure financial transactions. Using machine learning methods to assess the principles, potential, and constraints to Quantum Key Distribution (QKD) and PostQuantum Cryptography (PQC), the review is an improvement of the existing view of the current state of quantumsafe technologies. The opportunities and challenges in adopting these technologies in the key financial services, such as banking, digital payments, and blockchain, are analyzed. It has been identified that a hybrid approach that utilizes both QKD to perform secure key exchange and PQC to protect data over the long term can be considered an effective strategy. The review ends by identifying the main future research opportunities and the necessity of standardized, cost-efficient, and scalable quantum security solutions, guided by AI-informed insights, to protect the financial sector against future quantum attacks.
