What is Quantum Computing?

Quantum computing is a very interdisciplinary field of computer science, physics, and mathematics that uses quantum mechanics for problem-solving much faster than classical computers. This program involves research in hardware as well as in application development. Quantum computers use quantum mechanical effects like superposition and quantum interference to outperform classical computers in some problem-solving scenarios.

Its applications take advantage of this speed, including machine learning, optimization, and simulation of physical systems. Potential future use cases are portfolio optimization in finance and the simulation of chemical systems to solve problems not yet accessible to the most powerful supercomputers.

The Impact of Quantum Computing on Data Security

Quantum computing marks a significant shift in the data security landscape. Existing encryption, outlined in algorithms such as RSA (Rivest-Shamir-Adleman) and ECC (Elliptic Curve Cryptography), depends on the complexity of mathematical operations, including factoring large prime numbers or calculating discrete logarithms. These operations, which represent the mathematical foundation of modern encryption, may be rendered trivial for a suitably advanced quantum computer.

More Frequent Data Breaches

As quantum computing gains ground, so too will the interception, manipulation, and exfiltration of data. Businesses will suffer heavy losses, and one attack will cost an average of more than $4.24 million.

Use of the Stolen Information

Usability, if the data is stolen, is generally lost once it is encrypted. But quantum computing is about to change that. It will enable the thief to decrypt this currently unusable information. Cybercriminals often retain stolen data, expecting it to become useful in the future. Quantum computing can allow them to decrypt it, leading to heavy losses for most businesses.

More Prevalent Cyber Attacks

Cybercriminals can use quantum computing to intercept and read information, which can be used to facilitate man-in-the-middle attacks more efficiently, as well as credential-based and malware attacks.

Tighter Budget Restrictions

Not every company will have the capital to invest in quantum-proof security. Many companies will be forced to cut corners to stay compliant, so organizations could suffer from security breaches. The costs of infrastructure associated with special-purpose equipment and increased attack frequency will stretch cybersecurity budgets, making them less flexible even when more funds are allocated.

Increased Cybersecurity Budgets

Protection against quantum-computing-induced cyberattacks requires special-purpose equipment that is costly upfront. On the surface, higher budgets seem to be a good thing, but they actually result in a more acute eye being fixed on details and a narrower scope for mistakes, leading to lower flexibility of the budgets.

Implications of Quantum Computing in Cryptography, Drug Discovery, and Financial Services

Quantum computing is poised to significantly influence various sectors, particularly in cryptography, drug discovery, and financial services, due to its potential to process complex calculations much faster than traditional computers.

Cryptography and Cybersecurity

Quantum computing poses a significant threat to current cryptographic systems, such as RSA and elliptical curve cryptography, which could be efficiently broken by quantum algorithms like Shor’s Algorithm. This has led to a surge in developing quantum-resistant cryptography (PQC), with initiatives spearheaded by organizations like the National Institute of Standards and Technology (NIST). NIST and other agencies like the NSA and CISA are actively working on standards for PQC to secure digital communications against future quantum threats​.

Drug Discovery

In the pharmaceutical industry, quantum computing is being leveraged to revolutionize the drug development process by enabling the simulation and analysis of complex molecular structures at an unprecedented scale. Companies like POLARIS^qb are utilizing quantum technologies in combination with AI to expedite the discovery of novel therapeutics, significantly reducing the time and cost associated with traditional methods. This advancement is particularly impactful in developing treatments for complex diseases like cancer​ (McKinsey & Company)​​ (Nature)​.

Financial Services

Quantum computing offers significant financial modeling and risk management benefits through its ability to process large, unstructured data sets and perform high-dimensional and combinatorial optimization. Financial institutions are exploring quantum computing to enhance areas such as algorithmic trading, asset pricing, and portfolio optimization. However, the same quantum capabilities that aid in data processing also threaten the security of financial data, prompting the sector to invest in quantum-safe security protocols​
