(quirky music) (electronic music) – A quantum computer uses quantum physics to do calculations. The reason this is so amazing, is that it allows exponentially
faster calculation, compared to the digital
computer in front of you. To see how this is, recall
that normal digital computers uses bits, ones and zeros. In contrast, quantum computers
use Qubits, or quantum bits. Quantum bits can exist
as both a one and a zero. And so they can do two
calculations at once. This may not seem very
impressive, but each Qubit has a multiplicative effect. Ten Qubits can do a thousand
calculations at once, and 30 Qubits can do a
billion calculations at once. This still doesn’t mean that you just install your favorite app
on a quantum computer, and you’re ready to go. The code required for quantum
computers is so different, that it needs specialized
quantum algorithms to operate. And right now, there aren’t many of these. The quantum algorithms
are usually developed by physicists and mathematicians,
and so take advantage of the unique properties
of quantum physics. A quantum computer also
relies on probability, so the answers it produces
may not always be correct. This might seem odd. How can a computer give
an incorrect answer? It’s because in the
world of quantum physics, things are always a bit
fuzzy, and the answer may occasionally be wrong. This is why most
applications will be hybrid quantum-digital, to combine
the speed of quantum with the certainty of digital. An example might be modeling
the chemical process for fertilizer. The digital computer can
set up the basic model, and the quantum computer can determine the right energy levels. Since fertilizer is about 2%
of the world’s energy supply, this could have enormous consequences for food production, and energy costs. So, if you’re homework involves some of the most promising
applications, cryptography, molecular modeling,
financial predictions, yes, you will be doing your
homework on a quantum computer.

I look forward to more videos

It sounds like none of these reasons are economically convincing as we have all those supplies here in Earth, we do science with or without the moon but not necessarily are willing to pay so much to do those experiments and since the moon is so close to the Earth it's probably a good thing to have as a gas station but not a big difference.

So… what will make us do these things is having the budget to do them and it's all about getting that budget or not.

consequences?

Nice owl cup. You headed to Bohemian Grove? đŸ˜‰

You left out the part about how quantum computer's communicate with fallen angels in other dimensions and will soon screw the world to no end with the help of CERN. Jus sayin….
