Quantum Computing: Real-Time Applications


Quantum Computing(QC) can revolutionize the field of cryptography. In particular, it can provide unbreakable encryption through quantum key distribution (QKD). QKD uses the principles of quantum mechanics to securely spread encryption keys between two parties. This methodology is established on the fact that any attempt to intercept the quantum signal used to distribute the keys would cause it to be altered, and the recipient would be alerted to the presence of an intruder. Companies like ID Quantique and Toshiba already use QKD to provide secure communication channels for financial institutions and government agencies.

Drug Discovery:

QC is being used to simulate the behavior of molecules, which can help experimenters identify conceivable drug candidates. This approach can predict the effectiveness of various drugs and identify the optimal molecular structures for specific applications. For instance, IBM is using its QC platform to explore possible drug treatments for COVID-19.


Companies like DHL already use QC to upgrade their delivery routes and reduce conveyance costs. It can help enhance complex logistics networks, considering the weather, traffic, and other variables affecting delivery times. This can help companies reduce their operating costs and enhance their efficiency.


QC helps to optimize financial portfolios and predict market trends. Financial institutions can quickly analyze vast data using quantum algorithms and identify complex ways to catch up with classical algorithms. This can help them make better investment decisions and reduce their risk. For instance, Goldman Sachs is using QC to develop algorithms for trading options.

Artificial Intelligence:

Quantum computing can be used to optimize ML algorithms and enhance their accuracy. Quantum machine learning can help identify conventions in data much quicker than classical algorithms, which could lead to breakthroughs in fields like computer vision, natural language processing, and robotics. For instance, Google uses QC to enhance its voice-recognition machine-learning algorithms.


Using quantum computing, one can optimize the design of abstracts for use in renewable energy technologies. For instance, experimenters at Harvard University are using QC to explore the properties of goods that could be used to enhance the efficiency of solar cells.

Aerospace and Defense:

Quantum computing is being explored for use in aerospace and defense enterprises. One conceivable application is to optimize aircraft designs for maximum efficiency and safety. Besides, it could enhance the security of military communications and enhance radar systems.

Environmental Monitoring:

Using QC, one can simulate complex environmental systems and monitor changes in climate and ecosystems. For instance, Oak Ridge National Laboratory investigators use it to simulate the demeanor of large-scale environmental systems, such as the carbon and water cycles.

Supply Chain Management:

Optimizing inventory levels, reducing conveyance costs, and improving delivery times can optimize supply chain management through QC. Companies can reduce waste and enhance their customer service by using this.

Materials Science:

QC can design new materials with specific properties, such as superconductivity or high strength, and investigators at Volkswagen use it to design new goods for electric vehicle batteries.


Quantum computing is still a relatively new tech, but its possibility for revolutionizing a wide range of persistence is enormous. Experimenters are exploring the use of quantum computing in areas such as weather forecasting, protein folding, and space exploration, in addition to the applications discussed above. They are steadily developing practical QC systems that can be used in real-life, although they still need to overcome many challenges such as error correction and scalability.
