‘Hot’ Qubits Crack a Major Quantum Computing Challenge

Researchers might have broken one of the biggest obstacles to practical quantum computers with something called ‘hot’ qubits.

As many of you already know, the quantum computer is built around the quantum bit, or qubit.

The colder and more isolated the qubit is, the less likely it is to flip to another quantum state when it’s not supposed to. But well-isolated qubits are also difficult to keep cold, and the more qubits a computer has, the more heat the system generates, and so we have to figure out how to keep these large quantum computers operating at an optimal temperature either by improving the cooling systems or by creating qubits that can operate at warmer temperatures.

This is where researchers believe they have made a major breakthrough by using quantum dots embedded in silicon rather than basing their qubits off superconductors. This approach allows the qubits to operate at hotter temperatures…like 1.5 kelvin hot. That’s 15 times hotter than the main competing chip-based technology being developed by Google, IBM, and others.

So is this the breakthrough quantum computers need? Find out more in this Elements.

Can’t wait to play old school Runescape on one of these

The audio constantly going nigh silent in the middle of sentences makes this video very unpleasant to watch(rather, hear).

[sebastianelytron]

A group of qubits walks into a bar holding hands.



The same group stayed outside the bar.

[droogkloot]

Great vid but the audio sounds like a old VHS.

[heroicninja]

Hands up for those who watch this video even though they're still struggling on how normal comouters work. Count me in.

Scientists: Have major breakthrough in quantum computing

Will Smith: "Ah, that's hot."

[MrWabadabadoe]

Hey man, the gate on your audio is closing to fast making the ends of your words sound odd, good vid, cheers.

[NihongoLoFi]

Technology is advancing much faster than it used to. Everything you think is coming in 20 years really will come in 10... Crazy

[DEEPANJANBISWAS]

Nice video!
But zero direct/semi-direct eye contact when reading from teleprompter, is real odd.
Even the personal message in the end seems to be read from the screen!

"What would I use a quantum computer for?" Glad you asked that question. I'd use it to create a code snippet that would crawl around youtube and remove all the shitty segments where boneheaded growth writers insert dumb call-to-action texts to get a youtube host to create a fake sense of debate in the comments section in order for the video to get more attention. Pls, know your audience and either challenge us with these questions, or just leave it out and for those who genuinely have something to add without the unnecessary fake questions.
Otherwise a fan, and great content.

I dont wanna be mean, but your audio i this video hurts my ear..
Please take it as a constructive criticism...

[DopeAsThePope]

Very fascinating to see where quantum computers will take us in the future.
I'm 44 now and remember when I was a kid in 1984 my elementary school had just 1 computer that would roll around on a stand going room to room to be displayed to the kids.
An old Commodore 64, lol.
Crazy to think what COMPUTERS will be like in 44 years from now!

[Habernoo]

Been watching every single quantum computer related video they are so cool

[MacForaday]

"If you had a quantum conputer, what would you use it for?" Some thing we use everything for Pinky: Try to take over the world!

[vishalmishra]

Bits come in 3 flavors from general to more specific/constrained - quantum-bit (q-bit), probabilistic bit (p-bit) and classical bit (c-bit). They are respectively, complex-valued (probability and phase), real-valued (only probability, that of being 1) and binary-valued (probability of being 1 is 0%=0 for 0-bit and 100%=1 for 1-bit, no intermediate probability other than due to silicon defects).

[yassodude]

It sounds like you're using sidechain compression from the bass drum to your voice track lol

[billyhart]

I can't claim to know much about quantum electronics, but I imagine what this style of electronics could do for radio is out of this world.

[ricomon]

What would I use a quantum computer for? I'd use it for streaming Seeker videos, of course! ;-)

[icecream]

The audio is making my brain screams
Instead of focusing on the information on the video, my brain went nuts on his voice "why does it sound like that?"
