The Rise of Quantum Computing: Transforming Data Processing as We Know It

In the world of data processing, a revolution, also known as quantum computing, is underway that promises to reshape the foundations of information technology. Quantum computing, a revolutionary technology that utilises the principles of quantum mechanics, is rapidly emerging as a transformative force (Hyseni, 2023). In this blog, we will explore the rise of quantum computing and its potential to revolutionize data processing as we know it.

Quantum Computing

Quantum computing, unlike classical computing, relies on the principles of quantum mechanics to perform computations using quantum bits, or qubits (Hyseni, 2023). These qubits can exist in multiple states simultaneously, making it possible for quantum computers to solve complex calculations rapidly and efficiently. This difference opens up a world of possibilities for data processing, explains Hyseni (2023).

Significant milestones have been reached in recent years in the field of quantum computing. In 2019, Google’s quantum computer achieved “quantum supremacy” by demonstrating that it could perform a calculation remarkably quicker than what classic computers could (Roush, 2020). One of the most promising applications of quantum computing lies in its ability to solve complex problems that are practically impossible for classic computers to solve. This kind of computing can be beneficial to a number of industries / areas like; healthcare, climate change, AI, transportation and big data (Turner, 2023).

Continuing with a focus on data, with the rise of quantum computing, the landscape of data security is also set to change. Quantum computers possess the capability to break traditional cryptographic algorithms,which form the backbone of today’s cybersecurity protocols (CIO, 2023).  Some ways that quantum computing could potentially put data security at risk and what’s being done in response to this is discussed below:

  1. Breaking Encryption: Quantum computers have the ability to break many of the cryptographic algorithms that are currently being used to secure sensitive data (Parker, 2023).
  2. Public Key Infrastructure (PKI): PKI relies on public key algorithms to ensure information confidentiality and integrity. Quantum computers can hypothetically break these public key algorithms, potentially allowing for unauthorized access to sensitive information (Entrust, 2019).
  3. Post-Quantum Cryptography: The field of post-quantum cryptography has emerged in response to the vulnerabilities that are predicted to come with quantum computing. The researchers involved in this field are focused on the continuous development of new encryption methods that will resist attacks from quantum computers (Entrust, 2019).
  4. Quantum Key Distribution: Quantum key distribution (QKD) makes use of the principles of quantum mechanics to establish secure communication channels. QKD uses the properties of quantum entanglement and measurement to create unbreakable encryption keys. By sharing these keys, QKD offers a promising solution for secure communication even in the presence of quantum computers. (Toshiba Asia Pacific, n.d).

In conclusion, the rise of quantum computing marks a transformative era in data processing. While quantum computers continue to evolve and bring immense opportunities, they also bring challenges to the field of data processing.
