Quantum Computing for the Rest of Us: Demystifying Qubits & Practical Applications by 2030
Quantum computing: In very simple language
When we hear the name of quantum computing, people often think, "This is a very difficult thing!" But in reality, it is not that difficult to understand.

| Quantum computing: In very simple language |
The computers we have in our homes work with bits. These bits are either '0' or '1' - just like an electric switch is either 'on' or 'off'. They understand only two things.

But quantum computers work in a different way. They have Qubits. The biggest feature of Qubits is that they can be both '0' and '1' at the same time. Imagine, a magical switch that is both 'on' and 'off' at the same time! This amazing thing is called Superposition.

Another magic is entanglement. This means that two Qubits are connected to each other in such a way that if you change one, the other will also change immediately, no matter how far away it is from it. These two special things - superposition and entanglement - together make quantum computers very, very fast and more intelligent. They can do things that even today's biggest computers cannot do.
π Where will it be useful by 2030?
Quantum computing is still new, but by 2030 we will start seeing its benefits:
i) New medicines and good health: These computers will help in discovering new medicines. They will be able to tell how a medicine will work in the body, which will make treatment faster and better.

ii) More secure online world: Quantum computers may be able to break the online security we use today. But don't worry, they will also create new and stronger security techniques themselves, so that our online data will be even more secure.

iii)Understanding the weather and environment: These computers will give more accurate information about the weather and climate. This will help us to prepare better for natural disasters like storms or floods. They will also help in finding new, clean energy.

⚠️ It is a little difficult right now
Qubits are very delicate, so they have to be kept in a very cold place. These machines are very expensive and difficult to make right now. But scientists are constantly working to improve them.
