Google's Quantum Echoes Algorithm Surpasses Supercomputers in Speed

Google has a useful quantum algorithm that outperforms a supercomputer A few years back, Google made waves when it claimed that some of its hardware had achieved quantum supremacy , performing operations that would be effectively impossible to simulate on a classical computer. That claim didn’t hold up especially well, as mathematicians later developed methods to help classical computers catch up , leading the company to repeat the work on an improved processor. While this back-and-forth was unfolding, the field became less focused on quantum supremacy and more on two additional measures of success. The first is quantum utility, in which a quantum computer performs computations that are useful in some practical way. The second is quantum advantage, in which a quantum system completes calculations in a fraction of the time it would take a typical computer. (IBM and a startup called Pasqual have published a useful discussion about what would be required to verifiably demonstrate a quantum advantage.) Today, Google and a large collection of academic collaborators are publishing a paper describing a computational approach that demonstrates a quantum advantage compared to current algorithms—and may actually help us achieve something useful.

13,000 times faster sounds impressive to me. Really curious to see when quantum computing becomes available to the market. An excerpt from the article is below: "Google this week touted research demonstrating that a quantum computer could run a verifiable algorithm on hardware – a breakthrough that signals practical quantum computing could arrive in data centers faster than previously anticipated.The company published research in Nature demonstrating the first verifiable quantum advantage while running its out-of-order time correlator algorithm, called Quantum Echoes. Google says the algorithm can be used for large-scale computing problems, like learning the structure of molecules, magnets, and even black holes. Google says the algorithm can run 13,000 times faster on its Willow chip than the fastest classical computers." #quantumcomputing

Google Just Achieved Real Quantum Advantage — and It’s Actually Useful After years of debate over “quantum supremacy,” Google has unveiled something far more consequential: a quantum algorithm that genuinely outperforms the world’s fastest #supercomputer — by an astonishing 13,000x. Their breakthrough, called “Quantum Echoes,” isn’t just theoretical. It represents a step toward quantum utility, meaning quantum systems doing work that has real-world value. Here’s what’s revolutionary: 🔹 Quantum Echoes allow a quantum system to “move forward and backward in time,” amplifying interference patterns that classical systems simply can’t replicate. 🔹 The same computation that took Google’s quantum computer 2 hours would take the Frontier supercomputer over 3 years. 🔹 Even more compelling — this isn’t just math. Google used the algorithm to model molecular spin behaviors in Nuclear Magnetic Resonance (NMR), paving the way to uncover new molecular structures and improve material and drug discovery. ❓Why it matters: This is the first time we’ve seen both quantum advantage and quantum utility converging — proof that quantum systems aren’t just faster, but capable of solving previously unreachable scientific problems. Google isn’t alone in the race, but its 65-qubit machine has set a new benchmark for where we’re headed — a future where quantum and classical computing work hand-in-hand to unlock breakthroughs across chemistry, climate, and AI. 💬 ❓What do you think — will 2026 finally be the year we see quantum computing move from lab demos to commercial reality? ➡️ Share your perspective in the comments, and follow me for more breakdowns of emerging tech that’s shaping the next decade. https://lnkd.in/dgExVwin?

Alphabet’s Google has made a significant breakthrough in quantum computing with its “Willow” chip, which ran the “Quantum Echoes” algorithm 13,000 times faster than the world’s best supercomputers. This algorithm is verifiable and repeatable on other quantum computing platforms, marking an important step toward practical quantum applications within the next five years. The quantum computing advance opens the door for potential uses in medicine and materials science. The algorithm can examine molecular structures by computing atomic distances, a function applicable to drug discovery and battery design, although this would require quantum computers about 10,000 times larger than current ones. Despite this progress, experts note challenges remain, including moving toward commercially useful applications and achieving scalable fault-tolerance, which was not part of the current demonstration. The Google team, including 2025 Nobel Prize winner Michel H. Devoret, plans to continue scaling and refining their quantum systems to reach broader real-world deployment. #Semiconductors #India https://lnkd.in/gqGV8reR
