In recent years, many renowned companies and organizations are working on something that sounds very interesting and important: Quantum computing. This statement has probably raised the curiosity of many of us because it is a topic that causes us many questions. That is why today we have decided to clarify what exactly it is and how quantum computing can be useful for:
Our computers in the majority interact with the data represented in binary digits known as bits (0 and 1). In other words, everything is stored in bits. For computers, the bits are the presence or absence of voltage (1 or 0), or the change or preservation of the magnetic address on the magnetic hard drives. Computing is generally done by transistors that control the electronic signal’s passage (If it allows the signal to pass, it is bit 1 and if the signal is cut off, it is 0).
Quantum computing uses qubits instead of bits to represent data.
The power of quantum computing comes from the fact that bits are 1 or 0, but qubits can be 1 and 0 simultaneously, due to a property called superposition (where quantum particles are in multiple states at the same time) This increases the qubit computing power, since it can be used as 1 and 0 at the same time during the calculation, and in the end it becomes 1 or 0.
Superposition with other properties such as quantum entanglement can significantly reduce computing time compared to traditional computers. In other words, let’s say that 2 qubits get entangled, if one of the qubit states is changed, the other will also change, causing real parallel processing or computation.
Once this is understood, we can start to see the need to improve and implement this style of computing for the future. The clearest examples are the chips, many of us have noticed that they are getting smaller and smaller, and that is where the need for powerful computing on smaller devices arises. Quantum Computing is the most advanced way to process data that require less time and space.
Quantum computing can be a big change solving many of the existing problems right now.
But unfortunately there is a problem that we have not been able to solve, and it is the building of quantum computers. That machine have to be a piece of extremely complex equipment, it would work at a temperature close to absolute zero and have to be an extremely stable machine.
If we overcome these obstacles, quantum computing will revolutionize everything we know so far. This type of computing could facilitate the way to the SDGs. Quantum computing promises to be the ultimate engine for the optimization of global logistics, allowing the development of all areas of the planet. On the other hand, molecular structures can also be created, simulated and modelled and that means the improvement of the chemical industry and the science of materials, creating new alternatives and greener technologies
In conclusion, quantum computing means the end of everything we know about computing and the move towards a more sustainable future. If this powerful way of storing and working data is used correctly.
