Quantum Computer is a form of computer computation that uses Qubits (bits on normal computers) to complete complex computations or calculations that previously took thousands of years to complete in seconds.
Big companies like Google, IBM, Microsoft, and Airbus are investing heavily in this technology. Starting from finding cures for rare diseases, fighter aircraft designs, to market forecasts.
Despite having the highest level of interest, the continuity of the Quantum project is still arguably not experiencing major developments.
How Do Quantum Computer Work?
On a normal computer, it uses Bits (0 and 10) to process data. So for example 4 bits in one line, it can be described as follows:
But unlike a quantum computer, it uses Qubits (0 and 1 at the same time). If for example Bits are only denoted by 0 and 1 separately, the Qubits can represent both simultaneously. So 0 = 1 = 0.
At first glance it looks confusing, but it’s actually easy. For example, suppose that you currently want to hack your friend’s account password, which is exactly the same as the list of bits above.
If done on a regular computer, you have to enter everything one by one until you find the correct password combination.
Whereas on a Quantum computer that uses Qubits (0 and 1 at the same time), you only need to insert 4 digits and the computer will automatically look for the right combination.
However, later the results can mean right and wrong, because Quantum computing displays both the right and wrong answers. To rule out incorrect answers, the Grover Operator technique is used .
This is the advantage of quantum computers. Instead of trying all the possible passwords one by one, quantum computers try them all at once and figure out which one is the right one.
As a result, calculations that take a very long time to find the answer, with Quantum only takes a short time.
Quantum Computer Potential for the World
If quantum computers are developed further, it is clear that current technology will be very helpful in finding solutions to problems for an industry.
For example, for medical companies, with quantum computers they can speed up the process of finding new drugs for some rare diseases, new trading strategies, optimization of transportation routes for logistics companies, and many others.
According to tractica data, although the Quantum market is still relatively new, it is forecast that the total market revenue will increase in the next few years, increasing from USD$39.2 million in 2017 to USD$2.2 billion per year in 2025.
The Market Intelligence Firm projects that North America will be the leading region for quantum computing system adoption with revenues of $718.3 million by 2025, followed by Europe ($695.8 million) and Asia Pacific ($650.9 million).
