Quantum computing, once a purely theoretical concept, is now moving from the realms of science fiction to reality. With the potential to solve complex problems and accelerate computations that are beyond the capabilities of traditional computers, quantum computing is set to revolutionize various industries. In this blog post, we will explore the intriguing world of applied quantum computing, its potential applications, and what it could mean for our future.


The field of quantum computing is a fascinating intersection of computer science, physics, and mathematics. It leverages the peculiarities of quantum mechanics to process information at an unprecedented speed and complexity. The term ‘applied quantum computing’ takes this a step further, referring to the practical use of quantum computing technology to solve real-world problems and perform useful computations.

Applied Quantum Computing

Applied quantum computing is about leveraging the power of quantum mechanics to solve real-world problems. For instance, quantum computers could potentially revolutionize areas such as drug discovery by simulating molecular interactions at a level of detail far beyond the reach of even the most powerful classical supercomputers.

They could also transform financial modeling by optimizing portfolios in a way that takes into account all possible market conditions simultaneously. The global quantum computing market is expected to reach $2.2 billion by 2026, with a compound annual growth rate (CAGR) of 32.4% from 2021 to 2026, as projected by MarketsandMarkets. This suggests the market’s potential and growth opportunities in the field of applied quantum computing.

Understanding Quantum Computing

In classical computing, data is stored in binary bits that can either be 0 or 1. Quantum computing, however, uses quantum bits, or qubits, which thanks to the phenomenon of superposition can exist in both states simultaneously.

This allows quantum computers to process vast amounts of information in parallel, making them exponentially faster than classical computers when solving certain types of problems.

Exploring Applied Quantum Computing

Applied quantum computing refers to the implementation of quantum computation techniques to address real-world challenges. This involves developing algorithms and applications that can run on quantum computers, exploiting their unique computational capabilities to solve problems more efficiently than classical computers.

The fields of application are wide-ranging, from optimization and simulation to machine learning and cryptography.

How Does Applied Quantum Computing Work

Principles Of Quantum Mechanics

Quantum computing works by harnessing the principles of quantum mechanics. Unlike classical physics, which describes the world at the macroscopic level, quantum mechanics governs the behavior of particles at the microscopic level. Quantum computers exploit these quantum phenomena, such as superposition and entanglement, to process information.

Quantum Computing Technologies

Building a practical quantum computer is a formidable challenge. Various technologies are being explored, including superconducting circuits, trapped ions, and topological qubits. Each approach has its own strengths and weaknesses, and it is still unclear which technology, if any, will ultimately prove to be the most viable for large-scale quantum computing.

Quantum Algorithms

Just as classical computers run on classical algorithms, quantum computers require quantum algorithms to operate. These algorithms take advantage of the peculiarities of quantum mechanics to solve problems more efficiently than classical algorithms.

Notable examples include Shor’s algorithm for factoring large numbers and Grover’s algorithm for searching unsorted databases. Quantum computing is finding applications in various fields. A survey by Deloitte states that 92% of surveyed executives believe that quantum computing will have a significant impact on their industry within the next decade.

Real-World Applications Of Quantum Computing

The global investment in quantum computing research and development is projected to reach $31 billion by 2025, according to a report by Tractica. This indicates the increasing interest and commitment to advancing quantum computing technologies.

1. Encryption And Security

One of the most promising applications of quantum computing lies in the field of encryption and security. Quantum computers could potentially break many of the cryptographic systems currently in use, rendering them obsolete. On the flip side, quantum computers also hold the key to new forms of quantum cryptography that would be theoretically unbreakable.

2. Drug Discovery And Development

Quantum computing could significantly accelerate the process of drug discovery and development. By simulating the behavior of molecules, quantum computers could aid in the design of new drugs and treatments, potentially saving billions of dollars and countless lives.

3. Optimization And Logistics

Quantum computers have the potential to optimize complex systems in a way that is currently not possible. This could revolutionize fields such as logistics, where quantum algorithms could be used to optimize routes and schedules, leading to significant cost savings and efficiency gains.

4. Financial Modeling And Risk Analysis

In the world of finance, quantum computers could be used to model complex financial systems, providing insights into risk management, asset pricing, and macroeconomic forecasting. This could lead to more accurate predictions and smarter investment strategies.

The demand for skilled professionals in quantum computing exceeds the current supply. A report by IBM and Burning Glass Technologies revealed a 56% increase in job postings for quantum computing positions from 2019 to 2020.

Current Advances In Applied Quantum Computing

Collaboration and partnerships play a crucial role in advancing applied quantum computing. The IBM Quantum Network, for example, has grown to include over 125 organizations, fostering collaboration and knowledge-sharing in the field.

1. Quantum Supremacy

In recent years, there has been significant progress towards achieving quantum supremacy – the point at which a quantum computer can perform calculations that are beyond the reach of classical computers. In 2019, Google’s quantum computer successfully solved a problem in just minutes that would have taken the world’s most powerful supercomputers thousands of years to solve.

2. Quantum Computers In The Cloud

While building large-scale quantum computers remains a challenge, companies like IBM and Microsoft are already offering access to quantum computers through the cloud. This allows researchers and developers to experiment with quantum algorithms and gain practical experience in the field without needing their own quantum hardware.

3. Industry Adoption And Investment

There is a growing interest in applied quantum computing from both the public and private sectors. Governments and companies around the world are investing significant resources into quantum research and development, recognizing the potential impact of this technology.

Major players in various industries, including finance, healthcare, and logistics, are exploring how quantum computing can transform their operations.

Challenges And Limitations Of Applied Quantum Computing

1. Overcoming Noise And Errors

One of the major challenges in building practical quantum computers is dealing with noise and errors. Quantum systems are extremely sensitive to their environment, and even tiny disturbances can cause qubits to lose their quantum state, a phenomenon known as decoherence. Overcoming this issue requires sophisticated error correction techniques and advances in quantum hardware.

2. Scaling Up Quantum Systems

Another significant challenge is scaling up quantum systems. While researchers have been able to build small-scale quantum computers, building a large-scale quantum computer – one capable of running complex applications – is a much more daunting task.

This requires not only more qubits but also better control and connectivity between qubits to ensure reliable and accurate computations.

3. Ethical Considerations

As with any emerging technology, there are ethical considerations surrounding applied quantum computing. For example, the ability of quantum computers to break encryption could have profound implications for privacy and security. It is crucial to carefully consider and address these ethical concerns as we continue to develop and deploy quantum computing technology.
