IBM Just Committed to Having a Functioning 1,000 Qubit Quantum Computer by 2023

We're still a long way from realising the full potential of quantum computing, but scientists are making progress all the time – and as a sign of what might be coming, IBM now says it expects to have a 1,000 qubit machine up and running by 2023.

Qubits are the quantum equivalents of classical computing bits, able to be set not just as a 1 or a 0, but as a superposition state that can represent both 1 and 0 at the same time. This deceptively simple property has the potential to revolutionise the amount of computing power at our disposal.

With the IBM Quantum Condor planned for 2023 – running 1,121 qubits, to be exact – we should start to see quantum computers start to tackle a substantial number of genuine real-world calculations, rather than being restricted to laboratory experiments.

"We think of Condor as an inflection point, a milestone that marks our ability to implement error correction and scale up our devices, while simultaneously complex enough to explore potential Quantum Advantages – problems that we can solve more efficiently on a quantum computer than on the world's best supercomputers," writes physicist Jay Gambetta, IBM Fellow and Vice President of IBM Quantum.

It's a bold target to set, considering IBM's biggest quantum computer to date holds just 65 qubits. The company says it plans to have a 127-qubit machine ready in 2021, a 433-qubit one available in 2022, and a computer holding a million qubits at... some unspecified point in the future.

Today's quantum computers require very delicate, ultra-cold setups and are easily knocked off course by almost any kind of atmospheric interference or noise – not ideal if you're trying to crunch some numbers on the quantum level.

What having more qubits does is provide better error correction, a crucial process in any computer that makes sure calculations are accurate and reliable, and reduces the impact of interference.

The complex nature of quantum computing means error correction is more of a challenge than normal. Unfortunately, getting qubits to play nice together is incredibly difficult, which is why we're only seeing quantum computers with qubits in the 10's right now.

Around 1,000 qubits in total still wouldn't be enough to take on full-scale quantum computing challenges, but it would be enough to maintain a small number of stable, logical qubit systems that could then interact with each other.

And while it would take more like a million qubits to truly realise the potential of quantum computing, we're seeing steady progress each year – from achieving quantum teleportation between computer chips, to simulating chemical reactions.

IBM hopes that by committing itself to these targets, it can better focus its quantum computing efforts, and that other companies working in the same space will know what to expect over the coming years – adding a little bit of certainty to an unpredictable field.

"We've gotten to the point where there is enough aggregate investment going on, that it is really important to start having coordination mechanisms and signaling mechanisms so that we're not grossly misallocating resources and we allow everybody to do their piece," technologist Dario Gil, senior executive at IBM, told TechCrunch.

Will it play Doom?

In about 25 years, the computers of today will be utterly primitive. By then, you will be able to hold the world's information in a memory chip the size of your fingernail with plenty of room to spare.

About a trillion yottabytes.

I am committed to a million times more processing power than that by 2022. Doesn’t mean I will get there.

functions in real world applications the uses are unlimited.

Not really. There are whole classes of algorithms that have no advantage being run on quantum computers. Things like simulating chemical reactions is where they'll really shine.

How cold is ultra cold, absolute zero?

Lotus Notes ID files might survive.

The quantum computer might adequately run Notes for once.

A little sarcasm.

I despise Lotus Notes.

Anything complex, like protein foldings and pharmacy drug production or manufacturing of metamaterials will really be where quantum computers will benefit.

It will reduce costs of research

Doom?

No you silly! It will be a powerful new video game that takes graphics to a whole nother level! In this coming new powerful supercomputing era, the player will be walking down a hallway or corridor and be shooting at alien zombies! Can't wait!!!

You remind me of back many years ago when the city council was debating cable deregulation. One of the councilmen declared that we would be able to have 500 channels! A lady went to the mic and asked,
"When we have 500 channels, how many of them will be Geraldo?"

Their Indian programmers are not smart enough.

IBM cannot be trusted. They’ll turn the tech over to the CCP.

For example, all current military grade encryption could be broken in a matter of a few minutes...

And if someone has been recording traffic, they can go back and decipher it. The Brits used computers in the early '70s to crack WW2 era Soviet radio communications with its intelligence agents in embassies. They had been taken down, but never decrypted in the intervening 25+ years. Computers made it possible to do so.

You are thinking of applications we already know about, but with a excuse the pun, quantum leap in computer power things that either were to complicated or had never been thought about will become reality......
