Quantinuum

For decades, we’ve asked when quantum computers will outperform classical ones – but what if that’s the wrong question? A new framework from Quantinuum researchers, led by our Chief Scientist for Algorithms and Innovation Harry Buhrman, offers a powerful way to discover instances of quantum advantage hidden in the computational landscape. By introducing “queasy instances” (quantum-easy) – specific problem cases that are hard for classical computers but easy for quantum ones – this fresh perspective shifts the conversation from when quantum advantage will appear to where quantum advantage lies. This work provides a roadmap for the hunt for quantum advantage.

What if happiness and income weren’t just loosely related—but circularly correlated? While most of us are familiar with linear correlations (like income and health), life often isn't so simple. Topological data analysis (TDA) offers a way to uncover more complex patterns—like loops and voids—in high-dimensional data. These features are captured by quantities called Betti numbers. At Quantinuum, we've been exploring how quantum algorithms can estimate normalized Betti numbers—even in datasets where classical algorithms struggle. In our latest study, we mathematically characterize the kinds of datasets that cause classical estimation methods to break down. This is a crucial step toward identifying real-world data where quantum advantage can emerge. The implications? We’re getting closer to unlocking insights in data that were previously out of reach—thanks to quantum computing. Read more here: https://lnkd.in/edQREC5R

Don't miss the Bradford Quantum Hackathon 2025 in the UK City of Culture 👏 Read here for more information 👇

This October and November, we and our partners at University of Bradford School of Management, Bradford 2025 UK City of Culture and Aqora look forward to welcoming diverse teams of quantum experts and novices alike to the 𝐁𝐫𝐚𝐝𝐟𝐨𝐫𝐝 𝐐𝐮𝐚𝐧𝐭𝐮𝐦 𝐇𝐚𝐜𝐤𝐚𝐭𝐡𝐨𝐧 2025. Part of our International Year of Quantum Science and Technology program, this event brings together teams from diverse backgrounds in quantum computing, healthcare, technology, business, and the arts. The 𝐁𝐫𝐚𝐝𝐟𝐨𝐫𝐝 𝐐𝐮𝐚𝐧𝐭𝐮𝐦 𝐇𝐚𝐜𝐤𝐚𝐭𝐡𝐨𝐧 2025 challenges teams to build bold, quantum-powered solutions to real-world problems — pushing the limits of what’s possible when quantum technology meets culture in a city with a long tradition at the centre of industrial revolutions. Teams can register today and will be invited to the opening virtual event in preparation for a month-long collaboration period, with final presentations to take place in person at the stunningly restored Bradford Live hackathon venue.

A fascinating exchange at Quantum.Tech 2025 during the Industry Disruptor Panel on optimization challenges: 🔹 Helmut G. Katzgraber, Former Senior Practice Lead of Advanced Solutions at Amazon: “Once you have an optimization problem with 100,000 variables and 10,000 constraints, you will definitely give up on it...Talent is the biggest blocker right now. If we achieve quantum advantage we don’t have enough resource to deliver it. There will be a skills gap for another 10 years as a PHD is required” 🔹 Harry Buhrman, Chief Scientist for Quantum Algorithms and Innovation at Quantinuum: “You should look at small data, big compute problems. And they're also present in optimization. … It’s important that we look at optimization problems that are hard classically, for which we can find a good, easy, quick quantum solution. It won’t be for a world-changing problem at the beginning, but that is the start - that’s where we have to go.” A perfect example of the critical conversations happening here in Rotterdam - where today’s challenges meet tomorrow’s solutions. #QT25 #QuantumTech
