Quantum computers

Science and technology have been abuzz about quantum computers for years but the device is not yet affecting our daily lives. The nebulous quantum future became one step closer this November when the journal Nature published two papers that showed some of the most advanced quantum systems.

It's still too difficult to understand what a quantum computer is and what it can do, for that we have to know what a classical computer can do and how quantum computers differ from it.

In classical computers for solving a problem, you have to enter the formula as input which would be taken as binary digits such as 0s and1s by the computer. So you have to solve problems based on this stream.

But in quantum computers, your computer for instance can be placed in two different states at once. This principle called quantum superposition is used in quantum computers. Quantum computers could seamlessly encrypt data, help us make sense of the huge amount of data we have already collected, and solve complex problems that even the most powerful classical computer cannot The idea of the quantum computers is to basically make use of the principle of quantum superposition to process information. It's quite complicated to understand how this can be so powerful.

We all feel excited to know how a quantum computer exactly looks like, Here's the answer.

If you were to walk in a room with a quantum computer in it you would see a vacuum cell or tube and a bunch of lasers that shine into it. Inside we have a very low density of certain atoms. We have lasers to slow down the atomic motion very close to the absolute zero which is called laser cooling.

Both Google and Microsoft have just announced that they are expecting to reach a key milestone in the development of the technology in the nearest future.

Here are some interesting facts about quantum computing:

• Quantum computing aims to take advantage of unusual properties that matter exhibits.
• Quantum computers use quantum bits that can exist in both states simultaneously and many other states in between.
• Qubit exhibits the property of quantum entanglement, which is defined as the phenomenon of pairing or grouping of particles that cannot be measured or described independently, they are entangled and their state depends on that of particles in the group.

Finally, there's one thing beyond dispute - quantum computing is very interesting but it's too early to predict the time horizon of quantum computers. Many technical challenges are needed to be resolved before we reach this milestone.
