The next big thing in Technology?
The Technology sector has been a star investment performer in the past decade, but finding the next big thing and investing early is a real challenge, even for seasoned investors. If you?re interested in a long term investment that could potentially generate enormous returns, then the crazy world of quantum computers needs to be on your radar.
Quantum computers ? crazy but true
A quantum computer sounds like something you might find on Star Trek, but they are real and have the potential to transform the world in the coming decades. Einstein famously once said, ?I cannot believe that God plays dice with the universe.? But it turns out that Einstein was wrong, because at a subatomic level, the world obeys the laws of quantum mechanics, and randomness is an intrinsic property of all quantum systems. Unpredictability might not sound like a promising basis for a computer, but it?s the secret behind how quantum computers work.
What is a quantum computer?
In a conventional computer, the basic unit of storage is the binary bit, which can be either 0 or 1. In a quantum computer, the basic storage unit is called a qubit (quantum bit) and it has the sanity-threatening property of being both 0 and 1 simultaneously. This kind of weirdness is commonplace in quantum mechanics, and it?s why Einstein hated it. You might think it sounds like nonsense, but quantum mechanics has proved itself in experiment after experiment and there is no doubt in the scientific community about its correctness.
Anyway, back to the quantum computer. In a conventional computer it?s often necessary to loop over all the possible values of some variable and repeat a mathematical or logical operation for each possible value of that variable. A quantum computer on the other hand, because its qubits hold all possible values of a variable simultaneously, can perform the entire loop in a single operation. Complex problems that would require billions of operations collapse to an almost trivial calculation, making quantum computers capable of performing tasks that would be simply impossible in any conventional computer.
