A quantum computer works in a totally different way from a classical computer. Quantum bits or 'qubits' can exist in a superposition state of both zero and one simultaneously. This means that a set of two qubits can be in a superposition of four states, which therefore require four numbers to uniquely identify the state. So the amount of information stored in N qubits is two to the power of N classical bits.

it's amazing I don't even understand a single bit.

Yes, but how does the computer

Wasn't expecting Loki to do an explanation about quantum computing

This video should be titled “Italian Metalhead Explains About Qubits”

Really like how this professor teaches. He's very understandable.

Who else is still confused?

I lost it at the when he started explaining about the coefficient part

That physicist thought he was explaining himself but he really wasn't..

Well that explains a lot, still don't know a thing

That's the first time I've 'got' how quantum computers work. -'it's not the speed of the individual operations, it's the number of operations it takes to reach the result.' No magic. Andrea is a superb scientist. I love his explanations. Thank you!

almost 8 years since the video was made and i still think this is one of the best explanations i can find for my tiny brain to comprehend the basic definition of quantum computing.

For those wandering, why when you add up the coefficients in front of the possible states of the electron spin at

I have what scientists call QI or Quantum Intelligence, which exists in two states, before you measure it, I am both Intelligent and not, but once you measure it, what you find is that I am not intelligent 99% of the time. By the way, I don't even understand this enough to make an appropriate metaphor, and this is the 1% trying it's hardest here.

Finally someone actually explained how they work! I’ve know for years about how, “it’s nothing like a classical computer, it can have bits in superposition” but no one told me how to read the qbits or how they interact.
