How Quantinuum Uses Hardware, Software, and Talent For Historic Inventions


Insider Summary

  • In a historic experiment, a team of scientists led by Quantinuum creates and manipulates non-Abelians.
  • Non-Abelian Anyons can serve as a platform for fault-tolerant quantum computers, in other words stable quantum computers that can be unleashed on complex computational challenges.
  • Quantinuum officials recognize unique hardware and software expertise, along with scientifically driven staff for project success.

A team of scientists led by Quantinuum reports that they are able to create and — most importantly — manipulate exotic particles called non-Abelian anyons, which could pave the way for fault-tolerant quantum computers.

In experiments conducted using Quantinuum’s Quantum Computer System Model H2, the research team was able to demonstrate a non-Abelian topologically ordered state. Many experts consider this new — and, until now, never demonstrated — state of matter to be the most likely path to a quantum computer that does not require extensive error correction, so-called fault-tolerant quantum computers.

“Fault-tolerant quantum computing is our ultimate goal. Our world’s leadership in quantum computing continues to be showcased and proven by real progress, and the creation and manipulation of anyone non-Abelian to create topological qubits is another example that when extraordinary tools are given to brilliant people, they will find something extraordinary to use. done. with them,” Ilyas Khan, Founder and Chief Product Officer at How many, said in an announcement about the find. “This is the transistor moment for the quantum computing industry – and the fact that we have used a quantum computer as a machine tool to build topological qubits that is a significant step towards fault-tolerant quantum computing is further evidence of our longstanding belief that quantum systems are best explored and created by other quantum systems. This is precisely what Feynman anticipated in his now famous remarks that are so often cited as the basis for quantum computing.”

Perfect Platform

Quantinuum, arguably the largest standalone full-stack quantum computer company, relies on hardware, software, and — in short — talent sets to make discoveries.

The company’s quantum device, H2, was instrumental in this historic discovery, said Tony Uttley, COO of Quantinuum, in an exclusive interview with The Quantum Insider.

“On February 16, at 1607 GMT, for the first time, using our H2, we created and controlled these topological non-Abelian qubits – and the last part of the sentence, that we can control them is a very big part of the whole story,” said Uttley. “This is really only possible on this planet because we are using the H2 quantum computer. There’s a set of materials you absolutely must have to make it work. And they’re only available right now on the beautiful platform we just launched.”

The 32-qubit H2 has a new “racetrack” design that maintains all-to-all connectivity between the H1’s qubits. This means that any qubit in H2 can be directly entangled with any other qubit in the system

The H2’s unique design provides the perfect platform for experimentation for several reasons, adds Uttley. First, H2 can provide enough qubits, in this case a total of 30 qubits, which includes three additional qubits.

Experiments also require great precision, which is the strength of H2. Fidelity is important in quantum computing because it determines the accuracy and reliability of quantum operations and algorithms.

“The third thing you need to measure is the count in the middle,” says Uttley. “In this case, you measure the state in the middle, and then can take action. We really have to be able to take an understanding of what you just saw, and pass it back to manipulation of that state. We call this conditional logic.”

Managing all of these requirements at once requires extraordinary precision, even for a quantum computer. The H2 is up to the task.

“All of this has to happen at the same time for the experiment to work – and the only computer in the world that can do that is our H2 quantum computer,” said Uttley.

Henrik Dreyer, theoretical quantum physicist and scientific leader in the condensed matter group at How manyH2 words help turn theory into experimental reality.

“We all know that this is theoretically known and the pathway is valid, but being able to undertake this pathway, in particular, using target measurements is a key ingredient for that theoretical proposal,” said Dreyer.

Talent equipment

Both Uttley and Dreyer say Quantinuum’s emphasis on building teams that value science, indulge creativity, and focus on real business solutions is as critical to the success of finding and controlling anyone non-Abelian as quantum computers and H2. The building of this culture began with the formation of Quantinuum, following the merger of Cambridge Quantum and Honeywell Quantum Solutions.

“We really have at our core that if you want to accelerate how fast quantum computing is valuable to the world, you have to become an integrated company,” said Uttley. “You have to be able to know the hardware and what makes it work and you have to know the operating system layers and how to make the most efficient use of them with applications.”

The topological qubit project exemplifies Quantinuum’s commitment to using cutting-edge science to create practical quantum computing.

“In November 2022, our H2 was up and running and we gathered 50 scientists from around the world and said: This is what this amazing system does. What shall we show you?” said Uttley. “And in typical scientist fashion, they came up with 30. And in typical fashion went through and said, OK, let’s prioritize, and, as you can guess, the qubit topology project came to the top of the list.”

Where Will Quantum Fault Tolerant Computers Take Us?

Realizing that obstacles still stand in the way, the Quantinuum team is excited about where mastering topological qubits will take industry — and humanity.

Many uses of today’s quantum computers are made more possible with fault-tolerant quantum computers. Uttley sees devices playing a dramatic role in chemistry, encryption, and the life sciences, for example.

But using the device to investigate the fabric of reality remains a tantalizing possibility.

“Where we are now, we know what our system can do and we know what our system is good at,” said Uttley. “We have been able to take advantage of the fact that it works as a quantum computer to do things that only a quantum computer can do. In essence, our current system is a condensed matter physics engine. So if you’re a condensed matter physicist, or a high energy physicist, this is another tool you’ve never had before. It never existed on this planet. The government installed very large and expensive hadron colliders to be able to do this kind of physics work. But, now this tool exists.”

The team expects further development, but estimates that practical use of the topological qubits could be made in just 12 to 18 months.

“Ultimately, I think this experiment shows that if anyone wants to build and scale a completely universal fault-tolerant quantum computer, this approach is a good one to try because topological qubits are naturally more immune to noise, which is the reason that people have tried to do something with them for the last quarter century,” Uttley said.
