The founder of Cambridge-based Riverlane, Steve Brierley, predicts quantum computing will have its “Sputnik” breakthrough within years. “Quantum computing is not going to be just slightly better than the previous computer, it’s going to be a huge step forward,” he said. Phys.org reports: His company produces the world’s first dedicated quantum decoder chip, which detects and corrects the errors currently holding the technology back. In a sign of confidence in Riverlane’s work and the sector in general, the company announced on Tuesday that it had raised $75 million in Series C funding, typically the last round of venture capital financing prior to an initial public offering. “Over the next two to three years, we’ll be able to get to systems that can support a million error-free operations,” said Earl Campbell, vice president of quantum science at Riverlane. This is the threshold where a quantum computer should be able to perform certain tasks better than conventional computers, he added.
Quantum computers are “really good at simulating other quantum systems”, explained Brierley, meaning they can simulate interactions between particles, atoms and molecules. This could open the door to revolutionary medicines and also promises huge efficiency improvements in how fertilizers are made, transforming an industry that today produces around two percent of global CO2 emissions. It also paves the way for much more efficient batteries, another crucial weapon in the fight against climate change. “I think most people are more familiar with exponential after COVID, so we know how quickly something that’s exponential can spread,” said Campbell, inside Riverlane’s testing lab, a den of oscilloscopes and chipboards.

While today’s quantum computers can only perform around 1,000 operations before being overwhelmed by errors, the quality of the actual components has “got to the point where the physical qubits are good enough,” said Brierley. “So this is a super exciting time. The challenge now is to scale up… and to add error correction into the systems,” he added. Such progress, along with quantum computing’s potential to crack all existing cryptography and create potent new materials, is spurring regulators into action. “There’s definitely a scrambling to understand what’s coming next in technology. It’s really important that we learn the lessons from AI, to not be surprised by the technology and think early about what those implications are going to be,” said Brierley. “I think there will ultimately be regulation around quantum computing, because it’s such an important technology. And I think this is a technology where no government wants to come second.”
