Google Willow Pushes Us Closer to Mainstream Quantum Computing

Quantum computing has been around for quite some time now, but we have yet to see it become commercially viable. However, Google’s recent announcement of the arrival of Willow, a quantum chip that has reduced the error tendencies of some of its predecessors, proves we are closer than ever.

Willow is a big step toward making quantum computing a reality. Its speed is mind-blowing — Google says it can solve a problem in under five minutes that would take one of today’s fastest supercomputers 10 septillion years to figure out.

For perspective, that’s 10,000,000,000,000,000,000,000,000 years.

The best part about the new chip, according to Google, is its accuracy. Quantum computing has always had a bit of a wild streak, like a garden hose spraying everywhere with no one to control it. Willow hopes to change that by combining speed with accuracy, something we’ve never seen before.

How Is Google Willow Different?

Google unveiled its latest quantum processor, Willow, in December 2024. The company says the chip represents a giant leap forward in the field.

Based on its specs and capabilities, Willow could be the breakthrough that transforms quantum computing from a technical curiosity to a commercially viable tool.

We’ve already talked about how fast it is, putting it into perspective with all those mind-boggling zeros. But the real breakthrough isn’t just the speed – it’s the intended accuracy.

For decades, one of the biggest challenges for quantum computing has been reliability. As quantum systems add more qubits, the quantum equivalent of classical bits, they tend to become more error-prone. This is where Willow’s design stands out.

According to Google, the more qubits Willow uses, the fewer errors it produces. Tests demonstrated exponential progress in reducing error rates as the system scaled. Starting with a 3×3 grid of encoded qubits, researchers scaled up to grids of 5×5 and 7×7, and with each step, they cut the error rate in half using the latest advancements in quantum error correction.

The technology behind Willow is pretty advanced. The chip has 105 qubits, about twice as many as Google’s earlier Sycamore chip, but it is not just about the number of qubits. Their quality matters too.

Willow’s qubits can hold information for much longer due to significantly improved retention times, also known as T1 times. These times are now about five times better than before. This improvement means the qubits stay stable and accurate for longer, which makes a big difference in performance.

Willow & Commercially Viable Quantum Computing

Google Willow is a key step toward creating a powerful quantum ecosystem that could solve problems way beyond what today’s classical computers can handle.

The progress made with Willow opens up several possibilities for real-world applications. Quantum computers could break existing encryption (something known as ‘Q-Day’), pushing the need for stronger, quantum-resistant security systems.

They could also supercharge machine learning, leading to smarter and more efficient artificial intelligence (AI). Plus, they could help model complex molecular interactions, speeding up breakthroughs in new drugs and advanced materials.

Willow’s advancements in error correction are a significant benefit to companies developing commercial quantum solutions. While this progress is an important milestone in scaling problem-solving capabilities, it is just one of many steps forward.

Google acknowledged that it is still constrained by the same fidelity improvement limit, a factor of two, regardless of how many error-correcting bits are employed with the surface code.

The company has announced plans to explore alternative error correction algorithms that could be simpler than surface codes and potentially deliver superior performance.

The Current State of Quantum Computing

Quantum computing is still in its early stages, but the field is rapidly gaining momentum. IBM launched Osprey, a 433-qubit machine, last year and aims to build a 100,000-qubit system within the next decade.

Google has even bigger ambitions, targeting a million qubits by the end of the decade. Other key players in this emerging space include D-Wave Systems, IonQ, Rigetti Computing, Honeywell, Microsoft, and Intel. Many of these companies are already offering quantum computing services through the cloud.

According to Fortune Business Insights, the quantum computing market is expected to grow significantly, increasing from $928.8 million in 2024 to $6.5 billion by 2030. This represents a compound annual growth rate of 32.1%.

Venture capital funding for quantum computing surged by 700% between 2015 and 2023. One standout example is PsiQuantum, a quantum computing startup founded in 2016, which has raised over $665 million to date. The company has attracted investments from major players like BlackRock and Microsoft.

The Bottom Line

Scientists continue to face many challenges in developing large-scale quantum computers, and skeptics argue that it is still too early to get excited about quantum computing’s real-world applications.

History offers a useful perspective. For example, the concept of artificial intelligence was first introduced in the 1950s, but it took decades before AI saw practical applications, such as speech recognition or image processing.

Only in recent years, with advancements in hardware and algorithms, has AI truly transformed industries. Similarly, hard tech like quantum computing requires time.

But quantum is coming, and businesses should start thinking about how it will drive digital investment, reshape industries, and spark innovation.

It might not make a huge impact right now, but getting a good grasp of quantum applications today is key to positioning your company to take advantage of its potential over the next decade.
