Quantum computing is the holy grail of computer science, and it could be closer than we think.
Quantum Computing is the ultimate step for computers to take, and represents the pinnacle in computing technology. A quantum computer is infinitely more powerful than any computer in existence today, and if one were to be developed it would mark a change in the computing world of a level unseen since computers were first invented.
Normally, computers store information as a “bit”. A bit is stored in either an ON or an OFF state, and be interpreting the various combinations a computer can store and analyse massive amounts of data. However, as explained here, there is a limit to how powerfula computer can be made using bits. Once the amount of stored data reaches a certain amount, the time taken to run simulations and programs increases to a phenomenal degree.
Quantum computing introduces Qubits. Unlike bits, Qubits store information as an ON or OFF state as well as possibly storing it in every position in between. The power of Qubits becomes apparent when you realise that it can see every possible combination of Qubits, all at once. Billions of calculations and combinations can be made in less than a second. The power of computers increases a billion fold, with huge repercussions for society, science and human development as we know it. Sounds like the work of science fiction, right?
Except IBM recently announced they have found a way to stabilise Qubits for 100 milliseconds. Doesn’t sound like much, for a normal person. But for a computer capable of theoretically knowing everything? That’s a lifetime.
This is the future.
