BERLIN : This ’90s-Era Quantum Computing Idea Could Lead to a Massive Breakthrough
BERLIN : Quantum computer maker Quantinuum proved the merits of 1990s idea, catching and correcting errors as a calculation progresses.
Why it matters
This key step ultimately could potentially make the revolutionary machines practical, tackling problems in areas like materials science and medicine that are out of the reach of conventional computers.
Quantinuum, a leader in the nascent field of quantum computing, said Thursday it advanced a key technique for correcting errors in calculations done by the advanced machines, a development essential for them to fulfill their revolutionary potential.
A Broomfield, Colorado-based team improved its handling of qubits, the machines’ fundamental data storage and processing elements. Last year, they linked multiple ordinary qubits into a group called a logical qubit that’s more reliable. This year, they got a pair of logical qubits to perform calculations, said David Hayes, leader of the company’s theory group.
The work was notable because Quantinuum’s error correction technology keeps logical qubits stable longer than conventional qubits, and that’s key to coaxing useful work out of quantum computers.
The new achievement could eventually lead to developments that allow quantum computers to crack encryption, design more efficient solar panels and meet other promises of the complex machines. Such potential will likely encourage companies, governments and universities to continue investing in the technology though realizing its potential remains years away.
Quantinuum, created when Cambridge Quantum and Honeywell Quantum Solutions merged in 2021, isn’t the only company working on the idea. Big companies like Google, IBM, Intel and Microsoft are racing with startups like Rigetti Computing, IonQ and others to build the first practical, powerful quantum computers.
Qubits are individual atoms or other elements tiny enough to be dominated by the weird rules of quantum physics. It’s those rules that could help quantum computers solve problems that are beyond classical computers. On Quantinuum’s H1 quantum computers, that means prodding up to 20 electrically charged ytterbium atoms around with a laser inside a cold, airless chamber — an “ion trap.”
One problem with quantum computers is that qubits are hard to control and easily perturbed, derailing calculations. Logical qubits offer a mechanism to stabilize the situation.
Some qubits in the logical qubit flock are used for the data processing while others are used to interact with an ordinary outside computer. That conventional machine oversees the operation by monitoring the logical qubit’s state, checking for errors, and shepherding any errant qubits back into the fold. Quantinuum’s system repeats those error correction steps about five times a second.
With its results, Quantinuum has shown error correction ideas developed in the 1990s really are practical, said Russell Stutz, leader of Quantinuum’s commercialization efforts.
“There’s a path forward to getting lower error rates,” Stutz said.
A calculation with two logical qubits is still an early stage toward powerful, fault-tolerant quantum computers. Quantinuum’s test performed a simple test chore.
“You need more logical qubits to get to the level where this computer can do something that your classical computer can’t simulate,” Hayes said. He estimates about 50 are needed, and that, in turn, means hundreds of underlying physical qubits. That’s beyond Quantinuum today, though quantum computer makers are gradually headed that direction.

CAIRO: Indian-Origin Teen, Son Of IIT-JEE Topper, Wins Gold At World’s Toughest Programming Contest
CAIRO: Agastya Goel, a 17-year-old Indian-origin student from California, has won his second gold medal at the 36th International Olympiad in Informatics (IOI), which took place in Egypt. Agastya, son of Stanford professor Ashish Goel, secured the fourth overall rank at the prestigious contest, also dubbed as the world’s toughest programming competition for high school students.
Agastya scored 438.97 out of 600, while Kangyang Zhou of China topped the event with a perfect score of 600. A total of 34 students were awarded gold medals this year, including fellow Indian participant Kshitij Sodani, who ranked 21st.
This marks the 17-year-old’s second gold at the IOI. His father, Ashish Goel, made waves in 1990 by topping the IIT-JEE exam before going on to build a distinguished career at companies like Twitter and Stripe.
Who is Agastya Goel?
Agastya Goel, a junior at Henry M Gunn High School in Palo Alto, California, loves physics, computer science, and music. His hobbies include tennis, hiking, stargazing, and playing the guitar and piano.
Agastya’s interest in physics began at a young age, with his father introducing him to the subject during car rides and hikes. One memorable experience was learning about projectile motion while playing Angry Birds. This sparked a fascination with physics that has only grown stronger over the years.
Agastya’s competitive spirit was ignited through the USACO competition series, which he started preparing for in 6th grade. His hard work earned him a spot at the USACO training camp in his freshman year, followed by selection for the US IOI team.
Initially, Agastya considered majoring in computer science, but after exploring physics, he discovered a new passion. He spent 14 days intensively studying physics over winter break and was hooked.

CALIFORNIA: PM Modi Put India On World Map As Credible Innovator- IT Industry Leaders
CALIFORNIA: Indian-origin business leaders from the IT industry lauded Prime Minister Narendra Modi’s leadership for putting India on the global map as a “credible innovator and leader” for all nations to invest in and grow.
Speaking at the Indiaspora AI Summit 2024 on ‘Can Artificial intelligence be good force for future or not’ at the University of Stanford on April 26, Informatica CEO Amit Walia said, “India is perceived very differently in the global space. It’s a space of innovation. It’s a space of human capital. It’s a space of progress and innovation. And as we look forward, what Modi has been able to do is put India into the global map as a credible innovator, leader for all countries to invest in and grow.”
Speaking at the same event, Elastic CEO Ashutosh Kulkarni said that PM Modi and the government have been doing amazing work.
Mr Kulkarni said, “The Prime Minister and the government has been doing some amazing work and their focus on being open to innovation, their focus on industry, their focus on bringing the population, India is now one of the, it is the largest, most populous country in the world and bringing that population towards progress, the way they have tapped into the potential of this country has just been fantastic.”
Calling PM Modi’s era “amazing,” Mayfield Fund Managing Partner Navin Chaddha praised PM Modi’s leadership for ties between India and the US and his ability to connect the Indian diaspora which he stressed is doing extremely well in the tech industry. He noted that India is making progress in using technology and improving its infrastructure.
Navin Chaddha said, “The Modi era has been amazing, the kind of relationship they’ve been able to build with the United States. And to be able to connect the Indian diaspora, which is doing extremely well in the tech industry, hats off to them. And also the progress India is making in using technology, improving the infrastructure is just amazing. So, Mr Modi, keep doing what you’re doing.”
Rohit Jain, Speaker and Moderator – CIO, Harvard Business School, called on PM Modi to increase his guarantee, as he has always delivered. The event on Artificial Intelligence was organised to deliberate and discuss artificial intelligence.
He said, “Mr Modi needs to increase his guarantee because he’s always been delivering. So, I think his promises have been 100 per cent true. So, he now needs to promise 110 per cent and then again he’ll deliver on that. Mr Modi, thank you for what you have done, not only for India, but for the world.”
Priya Rajan, Managing Director, National Venture Coverage and Business Development, MUFG lauded PM Modi’s leadership in the entrepreneurial ecosystem. He stated that a number of VCs across the globe want to invest in India.
She said, “I see the Modi magic play is in the entrepreneurial ecosystem, which is an adventure ecosystem. So you can see the number of VCs now wanting to invest, not just where in India, investing in India, but world investors around the world wanting to do things. And you’re seeing kind of US, a ton of US global investors now setting up shops in India. I think that’s all coming back to what Modi magic has created.”
At the event, prominent Indian diaspora, along with the esteemed corporate leaders from the US shared their insights on the topic “Can Artificial Intelligence be a force for future or not.”
Rajya Sabha MP Satnam Singh Sandhu participated in the event. Notably, PM Modi has been advocating that artificial intelligence can provide a great support to help humanity’s development in the 21st century.
Taking to X, Satnam Singh Sandhu stated, “Indiaspora AI Summit, Stanford University, USA: Delighted to be a part of the summit where we had @ericgarcetti, US Ambassador to India, Indian Diaspora and business leaders from IT sectors who reiterated how PM @narendramodi Ji is leveraging AI to shape nation’s future strategy to build Viksit Bharat by 2047.”
“They highlighted PM Modi’s tech-savvy approach and his efforts to promote AI applications in various sectors like agriculture, health-care, and education for social development and inclusive growth. They also condemned the Western bias against India to rank them lower in parameters like Ease of doing business, and cite the irregularities while computing such rankings,” he added.
Earlier in December, PM Narendra Modi said that artificial intelligence is a dynamic issue and that India is working on creating a global framework for AI. He made the remarks while interacting with the participants of the Grand Finale of the Smart India Hackathon.
Speaking to the participants via video conferencing, the Prime Minister said, “AI (Artificial Intelligence) is a very dynamic issue. If one solution is brought in, the mischievous people will find another way. We have to be very alert to any new technology. It can be very useful if used within rules, but if it is used in the wrong way, it can create a lot of problems.”
“We all are aware of the generative AI-created deep fake videos that look completely real. Hence we need to be more alert before believing any photo or video. India is working on creating a global framework for AI,” said PM Modi.
