if the hackers break the laws of quantum physics in order to break the human laws,  do they go to jail or go get a nobel prize, or both ?

To sum up:
“It’s very complicated.”
“It’s so complicated that we can’t actually explain it other than stating that it’s non binary”
“It’s so complicated that it can change the way the world works”
“If you don’t get it, you’re beginning to understand it”

"the future is fundamentally uncertain but certainly exciting "...WOW!

@puzzleperson2007

A physicist friend of mine loves this quote...”if you say that you completely understand quantum physics, then it is obvious that you know nothing of quantum physics.”  So, kudos to you for helping the masses at least understand a tiny part of it!  I find the entire matter the most fascinating endeavor in science.

@RussellCatchpole

I must have missed the bit where she explained how quantum computing works :-(

@JJ-kl7eq

Thanks for making that quick.  I can now relax in a quantum of solace.

Quantum computing NOT explained in 10 minutes

@abelkips6627

Amitab bachan in the movie sholay had the quantum physics coin.

@d.e8282

I'm looking forward learning more (and understanding in my own way, by being confused) about this topic that lures and fascinates me and I consider Shohini Ghose managed to speak about a large scale of it in a beautiful way.

@Timlagor

The coin-flipping thing told me absolutely nothing about how quantum computers work

@JustinY.

TLDR It just works

@Greasyspleen

"If you are confused by quantum, don't worry. You are getting it." Wow, that's a really sly way of pretending you're explaining something when you aren't at all.

@NK-fx1qs

There is no spoon. You meant a fork. No, it's a spork.

@GeorgeMuammar

It must be a superposition of an explanation and a non-explanation

Quantum computer: "It's MA'AM!"

The real question is can it run minecraft with shaders?

@hadensnodgrass3472

They didn't even talk about what this means for specialized mathematics and storage capacities. A classical bit(Binary Digit, [0, 1]) is an characterized by a O(n^2), while a qubit(Quantum Bit) is characterized by a O(2^n). This makes seemingly enormous problems somewhat more manageable. For example: Say a classical computer the size of earth would have about the same computing power as quantum computer the size of an elephant(theoretically). 

They fundamentally work differently, so don't expect quantum computers to make your phone or laptop any faster, but for the scientific community that need solutions to extremely large data-set problems, or fundamentally complex can now be rapidly calculated.

@pc300000

Great job Dr. Ghose. I love simplifying complex stuff and your explanation of such a complex topic was brilliant. Especially, the idea that it is a fluid mix and that the computer will un-mix after the user. GREAT JOB!

@haydenhoodless2055

Actually I did kind of get this. We know that modern computers work with bits representing 1s and 0s and combinations of them to represent data. Bits can only ever be a 1 or a 0, but never both at the same time, the same as when you flip a coin and see the result, you can't have heads and tails at the same time. With a quantum computer however, bits can be both 1 and 0 at the same time. If you understand Schrodinger's cat, it's basically the same principle, it's only when you look into the box will you see whether the cat is dead or not, but you can never know the answer until that, so you have to accept both possibilities at the same time. That's why quantum encryption is unhackable, because even if you manage to "see" the data in it's quantum form, it's kinda like you're trying to figure out whether the cat is dead or not. 


If you ever delve deep enough into chemistry and physics, you might have heard that, rather than orbit the nucleus like a planet in a predictable path, it's kind of impossible know where exactly an electron is, it's at every point around the nucleus at the same time whilst also not being there as well. *mind explodes*. 


The fact that we struggle with these mind boggling concepts and pinpoint things is precisely why the quantum computer is useful. It's bits behave the same way. That's why it's useful for chemistry, because it imitate the behaviour of atoms in the same black magic way, we can model reactions without having to worry about the infinite crazy possibilities the direction of a particle might fly off to, and then translate the important information to us in a digestible format. 


At least that's what I'm getting.

@kennetharmbruster

I actually thought it was the best explanation of quantum computing I’ve heard yet, I’m endorsing this woman.
