Introduction to Quantum Computing
Overview of quantum computing
In quantum computing, the quantum mechanics uses a combination of mathematics, computational science, and information theory. There will be usage of electrons or protons and quantum bits or qubits which are the particles that exist in 0 or 1 at the same time. The main concepts in quantum computing are qubits, superposition, entanglement, quantum interference, and quantum gates.
Importance of cyber security
From using personal smartphones to various government platforms in our daily lives is involve with the digital revolution and the risk of cyber threats. Consequently, design of cybersecurity to protect against various attacks. It helps with data protection and safeguarding information from various breaches. Moreover, this is used as defense mechanism for national security. In maintaining the privacy of information (Bhushan, 2023). This assists to maintain its reputation and trust by introducing cyber security measures.
Fundamentals of Quantum Computing
Generally, the qualification of quantum mechanics to be able to solve problems beyond the computational capacities in the field of computer science is known to be quantum computing. Qubit is known to be a binary bit which is the unit or basic information that is used for encoding the data in quantum computing. The possibility of the availability of qubits, represented in 0 or 1 values is known to be a superposition (Hurley & Smith, 2023). More quantum particles that is measured either up or down are known to be entanglement. In classical computing, the values are either 0 or 1. Logical operations are followed and data is stored in the same memory. Multiple states such as 0,1 or both exist simultaneously in quantum computing. Perform various calculations.
Shor’s algorithm solves problems such as integer factorization in classical algorithms. It uses the RSA encryption technique which has public and private keys for encryption and decryption which produces security measures. Moreover, it protects against quantum attacks. Grover’s algorithm, it uses an advanced encryption standard where 128 binary keys is used exponentially (Zhang & Li, 2022). Also, it manages the quantum attacks. It continues its expansion for data processing and enhanced quantum applications.

Security measures and limitations of cyber security
Encryption Techniques
The encryption and decryption uses the same keys in symmetric encryption. Then, sharing of the secret key between the two operations. Examples such as AES, DES, and Blowfish are the encryption algorithms. The public key encryption technique is asymmetric where both the public key and private key. For encryption public key is used and the private key for decryption (Villanueva, 2024). For example, it is the RSA algorithm.
Common threats and limitations
There are various threats such as phishing attacks which involve revealing sensitive information, and ransomware attacks where it is infect the website. Similarly, the malware sign viruses have access to damage the networks by introducing malicious software. Data breaches are due to weak passwords and misconfigured databases. The denial of service and distributed denial of service attacks include system inclusions (Li & Liu, 2021). The man-in-the-middle attack helps attackers inject malicious content.
Encryption helps protect private and personal data which makes hackers not understand the data and even if there is a chance of a data breach the encryption provides the data to be safe and protect the sensitive information (Cocoara, 2024). Defense against cyber threats and cybercriminals for misuse of data. To avoid quantum threats there is post quantum cryptography which uses encryption algorithms for classical and quantum. It has also introduced various algorithms for code-based cryptography and hash signatures are used to make the encryption tighter for cyber security.

Threats posed by quantum computing to cybersecurity
There would be computational difficulty for mathematical problems like prime numbers factorization and logarithms that use encryption methods such as RSA and elliptic curve cryptography. Also, it solves long problems by providing security and encrypted data. Generally, the Shor’s algorithm is an advanced technique for factoring large numbers and gives advanced classification by breaking the RSA encryption. It breaks encryption algorithms and protects sensitive data including transactions, security secrets, and personal information. The cyber security maintains the confidentiality of digital communication. Therefore, by imposing cryptographic methods, it saves sensitive information.
As a banking sector, it involves various financial services so digital banking uses encryption algorithms such as RSA and ECC to protect against attacks in financial transactions. To solve efficient problems in banking use Shor’s algorithm. The security of cryptocurrencies and banking systems are maintained through digital quantum computing. In e-commerce platforms there are various payment, personal details, and shipping addresses these are all prone to data breaches. By the usage of mechanisms such as SSL/TLS which secures online transactions. There are many private concerns about personal communication by using quantum-enabled decryption techniques. Moreover, it protects sensitive information and avoid unauthorized access for any data breaches.
