In Layman’s Terms: Quantum Computing Explained in 60 Seconds

If you’ve ever wondered what quantum computing is and why it’s so important that it’s constantly brought up in the context of cutting-edge technology, rest assured that you will understand by the end of this post. It’s not rocket science!


Modern computers run on circuits. Circuitry, which is based on electrical flow, can only have one of two states: on (electricity is flowing) and off (electricity isn’t flowing). These states are depicted as 1 and 0, respectively, and one state represents the smallest possible bit of data.

Quantum computing turns this on its head, as explained in this off-the-cuff video by Prime Minister of Canada, Justin Trudeau:

This is obviously a simplified explanationthe real mechanics are far more complicated How do Optical and Quantum Computers work? The Exascale Age is coming. Do you know how optical and quantum computers work, and will these new technologies become our future? Read More — but it does capture the general essence of the idea. Quantum computing allows for greater “information density” and can process multiple bits of data simultaneously.

One can only imagine how beneficial this could be for the future of computers and electronics. It wouldn’t be a stretch to say that it would change the face of technology as we know it 5 Disruptive Technology Breakthroughs That Will Shock The World Disruptive technologies, like the Internet, industrial agriculture, and aeronautics, have profoundly shaped the world and our daily lives. Here are five technologies that are on the cusp of having a disruptive impact in coming years. Read More .

    What a pointless post. A quick google search on quantum computing tells you the "general essence" in couple of lines without having to click anywhere.
