When 2 + 2 is not equal to 4 anymore

Is it possible?



By quantum computing.

From the article The Transformations Promised By The Quantum Internet,

Unlike the traditional data encoding based on bits, the quantum world uses data encoded in quantum bits — or qubits — that are inherently different from the traditional coding of information into a sequence of 0's and 1's. Qubits, in contrast to bits, are not binary in their nature, meaning that they can, in fact, hold two states at once, rather than one at a time — a phenomenon known as superposition.

Is this future happening anytime soon?

Well, one thing is for sure. Big tech companies are doing something about it.

From the article IBM quantum computing development roadmap envisions applications running 100 times faster:

“IBM believes it has an achievable timetable to advance its quantum hardware to reach the power and reliability that will allow for commercial applications within 5 years.”

From the same article:

“If you’re a software developer, with this roadmap, you can decide where and when you should jump into quantum,” Sutor said. “This is obviously extremely important because developers are people who will be creating the software for all of us. And on the other hand, if you’re looking at this from a company perspective, they’re saying, ‘When will quantum be powerful enough to be relevant to me?’ And they’ll turn to developers for answers to that question. This roadmap should give them confidence that we will continue on a pace of very aggressive developments.”
