Let’s break down this game-changing technology and see why everyone’s excited about it.
The Magic of Quantum Computing: It’s All About the Qubits
Quantum computing is nothing like traditional computing. Think of a regular computer as a coin that can only land on heads or tails. Now, imagine a coin that can be heads, tails, and everything in between—simultaneously. This is the power of quantum computing.

At the core of quantum computing are qubits, the fundamental units of information. Unlike classical bits, which represent either a 0 or a 1, qubits can exist in multiple states simultaneously, thanks to the principles of superposition and entanglement. This enables quantum computers to perform parallel computations, making them exponentially more powerful than traditional computers when it comes to solving complex problems.
When you combine lots of these quantum bits (qubits for short), you get something truly magical. It’s like having millions of parallel universes working on your problem simultaneously.
Now, just how fast is Willow?
Here’s a mind-blowing comparison: Willow can solve problems so complex that our best supercomputers would need 10 septillion years to crack them (that’s a 1 followed by 23 zeros). To put that in perspective, that’s way longer than the universe has existed. Willow does it in five minutes!.
This wasn’t a fluke – Willow’s capabilities were tested using the random circuit sampling (RCS) benchmark, which is considered the hardest task for quantum computers. And Willow didn’t just pass; it crushed it!
This astonishing performance solidifies Willow as a significant step toward realizing practical, large-scale quantum systems. By successfully handling tasks that classical computers simply cannot, Willow marks a new era for quantum computing, offering unprecedented potential for future applications in science, medicine, and beyond.
The Green Side of Quantum: Sustainable Innovation at its Finest
Now, here’s where it gets interesting. Google isn’t just making faster computers; they’re making them smarter and greener too. But before we dive into their breakthroughs, let’s talk about how we measure the quality of these innovations.
Measuring Innovation via SPPQM
The SPPQM (Sagacious Patent Portfolio Quality Mix) offers a systematic approach to assessing the significance of patents. Utilizing a percentile scoring system, where a score of 0.99 signifies that a patent ranks in the top 1% of all patents, this metric evaluates various factors such as citation frequency, technological impact, and scope of protection. Patents that achieve higher SPPQM scores are more likely to result in impactful technological advancements and commercial success.
In addition, the Sagacious IP’s GREEN100® Index introduces another layer to this evaluation. This annual ranking highlights organizations that are pioneering sustainable technologies, with a particular emphasis on patents categorized as Y02 and Y04S, which pertain to climate change mitigation technologies.
In this year’s GREEN100® analysis, two notable quantum computing patents from Google were identified, showcasing the intersection of cutting-edge technology and green innovation.
Case Study: The Two High-Quality Patents
Google has two patents, that stand out in the quantum computing space for their high-quality scores and innovative potential. Let’s discuss these:
- US11238000B2 – Chips Including Classical and Quantum Computing Processors

The Challenges (Because Nothing Worth Doing is Easy)
While the potential of quantum computing is vast, significant challenges remain.
Let’s be real – quantum computing isn’t all smooth sailing. One of the biggest challenges in quantum computing has been managing errors. Qubits are highly sensitive and prone to interference, making it difficult to maintain their quantum states. As more qubits are added to a system, the error rate tends to increase, and this leads to a loss of quantum coherence, undermining the computer’s potential.
Willow, however, addresses this issue with groundbreaking quantum error correction techniques. By exponentially reducing errors as the number of qubits scales up, Willow maintains quantum coherence, making it one of the first systems to demonstrate error reduction while scaling. This achievement has been a significant milestone in the field, known as being “below threshold”—a term coined to describe when error rates can be controlled and mitigated as qubits increase.
Other issues include qubit stability, scaling quantum systems to handle complex real-world applications.
However, with these challenges come tremendous opportunities. As quantum technologies mature, they could revolutionize industries such as pharmaceuticals, logistics, and cybersecurity, offering the potential to solve problems that were once considered insurmountable.
What’s Next? The Future is Quantum!
Imagine this: faster treatments for diseases, more accurate climate models, and encryption so secure it’s practically unbreakable. These aren’t just dreams anymore. With breakthroughs like Willow leading the charge, we might be entering the quantum age sooner than we think. Who knows? In just a few years, quantum computing could be as common as smartphones are today!
We’re on the cusp of a quantum computing revolution, led by advancements like Google’s Willow chip, which is pushing the limits of computational power while aligning technology with sustainable innovation.
