Honeywell recently announced it created the biggest, baddest quantum computer ever made with 64 qubits. Here is what qubits are all about.
You probably know by now that regular computers use bits to hold information. Each bit of information is either a 0 or a 1. So when a regular computer, even supercomputers, process information, they are powerful because of the speed at which they do one calculation at a time.
Quantum computers use qubits as the basic unit of information. The qubit isn't just 0 or 1. It can be both. That is called superposition and it is what allows quantum computers to work on millions of computations at the same time. And that means that immensely complicated problems can be solved before the best super-computers can get started.
Most attempts at quantum computing have run into problems with storing information or just preserving the existence of qubits. But these problems seem to have been mostly solved and stable machines have been created.
