A Quantum computer includes a microprocessor chip with a billion operating devices integrated together to work - qubits. Rather than operating separately like normal computers which solves problems step by step, they do all the steps at once. Qubits only operate in massive machines that have extremely low temperature to work properly.

Quantum Computers Explained – Limits of Human Technology

Each microprocessor chip, contains basic modules, that contain logic gates, that contains transistors. A transistor is the simplest form of a data processor in computers. Logic gates sends out a particular bit, a combination of logic gates form basic modules. Basic modules multiply what the logic gates have sent out.

Quantum computers have the potential to solve problems, such as the design of new medicines, or new ways to solve the world's energy problems. They can also solve problems in seconds that would take normal computers years to solve. This can be achieved with microprocessor chips.

Quantum Computers are designed to be more energy efficient than normal computers. It is stated that by 2040, we will not have the capability to power all the computers around the globe if we continued to use normal computers. Not only do quantum computers save energy, they also get the job done faster than normal computers.

This technology will change the speed on how medicines will be made, chemists need to evaluate the interactions between molecules, proteins and chemicals one by one, the quantum computer can do it simultaneously. Another change would be weather forecasting, the weather isn't always estimated correctly. Since quantum computers can analyse all the data at once, meteorologists will have a much better idea of certain weather on a certain day.

Quantum computers will help to streamline traffic control whether its in air or on land. They will be able to quickly calculate the fastest route which allows for efficient scheduling and would reduce traffic jams. For similar reasons, quantum computers are also powerful for optimising supply chains, air traffic control, fleet operations and deliveries.

There is a significant work that has been done to develop online security while using quantum computers, such as the quantum key distribution, a very secure communication method that requires a key to decipher a message.
