Quantum computing exploits the bizarre behavior scientists have observed for decades in nature’s smallest particles. They are atoms, photons, or electrons. At this scale, the classical laws of physics cease to apply. Then we move on to quantum rules.

Researchers don’t understand everything about the quantum world. But they do know is that quantum particles have immense potential. It is especially for containing and processing large amounts of information. Getting to grips with these particles in a quantum computer could trigger an explosion in computing power.

That would dramatically advance innovation in many areas requiring complex calculations. This includes drug discovery, climate modeling, and optimization, financial or logistics. Bob Sutor, head of the quantum section at IBM, explains to ZDNet: “Quantum computing is our way of emulating nature to solve extraordinarily difficult problems, and to make them affordable.” Now let us see how Quantum Computing works in computers.

What is a Quantum Computer?

Quantum computers come in different forms, but they’re all based on the same principle. They house a quantum processor. These quantum particles can be isolated for manipulation by engineers. The nature of these quantum particles varies. Also, the method used to control them varies from one approach to quantum computing to another. Some methods require cooling the processor to freezing temperatures.  Others play with quantum particles using lasers. But they all have the goal of finding out how to best harness the value of quantum physics.

What is the Difference Between a Quantum Computer and a Classical Computer?

The systems that we have been using since the 1940s in various forms are known as classical computers. They are based on bits. It is a unit of information that feeds into every calculation performed in the device. In a conventional computer, each bit can take the value of 1 or 0 to represent and transmit the information used to perform the calculations. Using bits, developers can write programs. These are sets of instructions read and executed by the computer.

How does Quantum Computing Improve Classical Devices?

At the heart of any quantum computer are qubits. They are also called quantum bits. They can be freely compared to the bits that process information in classical computers. Qubits, however, have very different properties from bits. They are made up of quantum particles that occur in nature. These are the same particles that have obsessed scientists for many years.

One of the properties of quantum particles most useful for quantum computing is known as superposition. This allows quantum particles to exist in multiple states at the same time. The best way to imagine layering is to compare it to throwing a coin. Instead of tossing a coin, quantum particles are the coin as it spins. About Quantum Computing this is most essential.

By controlling quantum particles, researchers can load data into them to create qubits. With layering, a qubit does not have to be 1 or 0. It can be both at the same time. In other words, while a classic bit can only be a coin toss, a qubit can be both a coin and a coin. This means that, when asked to solve a problem, a quantum computer can use qubits to perform multiple calculations at once in order to find an answer, exploring many different paths in parallel.

Why is Quantum Computing so Important?

The time savings researchers predict from quantum computing are not in the order of a few hours or even a few days. Rather, it is about being potentially able to calculate. In just a few minutes, the answer to problems that today’s most powerful supercomputers can’t solve in thousands of years. They range from modeling hurricanes to the cracking of encryption keys protecting the most sensitive government secrets.
