Quantum Computing, which was once limited to research labs, has now entered real life as well. It has made its presence felt in sectors like healthcare, finance, cybersecurity, energy and logistics and in the coming time, it can change the face of entire industries. Let us know what quantum computing is and how it is becoming a game-changer for the entire world including India.
What is Quantum Computing?
In simple words, while normal computers work only on 0 and 1 (bits), quantum computers use “qubits”. These qubits can be in many states simultaneously (called superposition) and can also be connected to each other (called entanglement). This is the reason why quantum computers can perform certain tasks very quickly and accurately, which is beyond the capability of classical computers.
Where is Quantum Computing being used?
1. Healthcare and Drug Discovery
The most important use of quantum computing in the healthcare sector is in discovering new medicines and understanding small molecules. Our old computers fail to understand the process of large and complex molecules because many things have to be understood simultaneously. But with the help of quantum computers, these particles can be understood in their smallest form (at the atomic level) in a simple way.
Latest update: In 2024, Google Quantum AI scientists used quantum simulations to understand the workings of the enzymes (Cytochrome P450) that make medicines effective in our bodies. This will make it easier to develop personalized medicines.
2. Cybersecurity and cryptography
While quantum computers can break old encryption systems, they can also create ultra-secure systems like Quantum Key Distribution (QKD).
Latest update: In June 2025, DRDO and IIT Delhi successfully showcased quantum-secure communication across a 1 km distance. This can make quantum encryption a standard for data security in the future.
3. Optimization in logistics and supply chain
Quantum computers can solve tough problems like traffic, delivery, and warehouse management in minutes. Volkswagen and DHL have implemented quantum algorithms to improve route optimization. In the future, just 5-10% optimization can save crores of rupees in industries.
4. Financial Modelling and Risk Management
Understanding the mood of the financial market, making investment plans, and predicting risks can become easier with quantum computing.
Latest update: In 2024, JPMorgan Chase worked with Quantum startups to work on trading strategies and credit risk. This will make future investments more precise and less risky, as well as make it easier to track market fraud.
5. Energy and Materials Science
Quantum computing is proving to be a boon for batteries, superconductors, and clean energy technologies.
Latest update: In 2025 , scientists at QuEra Computing used quantum computers to understand battery design issues that could lead to batteries that are more energy efficient.
Top Quantum Updates of 2025
- Google’s Willow Chip: In December 2024, Google launched a chip that controls error correction to a great extent.
- Advantages in quantum simulation: A March 2025 study showed that low-energy states of quantum systems can be found efficiently. Whereas this task is extremely difficult and time-consuming for classical computers. This will directly benefit industries like pharma and material science, where such simulations are very important for making medicines and new materials.
- Companies like SandboxAQ have introduced real-time quantum navigation systems like ‘AQNav,’ which solve problems like GPS jamming by using AI and quantum sensors.
But there are challenges too…
- Quantum computers are currently very sensitive and need to be kept cool at zero degrees to operate.
- There is a huge shortage of specialists. There are only less than 1000 quantum PhD holders in the whole world.
- Scalability and efficiency will take more time.
Final Note: The Quantum Future Is Not Far Away!
Quantum computing is no longer just a fantasy but is showing its impact in the real world. From healthcare to finance and energy to logistics, this technology is going to change the game in every field.
However, this journey is not over yet. Business and government will have to prepare for the Quantum Era. They will have to invest in research, create quantum-ready systems, and prepare people who can work in this field.
