Innovations Driving Quantum Computing Scalability

🔴 NEW ARTICLE: Quantum Now Has a Path to Scale. Seed IQ Just Proved It. This isn’t theoretical. This isn’t simulated. ➡️ We ran Seed IQ (Intelligence + Quantum)™ on live IBM quantum hardware ➡️ Under real noise conditions ➡️ And held system-level fidelity at ~0.969, while preserving coherence and entanglement with two bell pairs across 3 logical qubits ▪️ While standard approaches decohere and collapse under these same NISQ conditions. This changes the quantum conversation entirely. 🔸 🔸 Seed IQ just surpassed the most advanced solutions for QEC (Quantum Error Correction) that exist in the quantum computing field today (in known literature and published research)... … while introducing something quantum has never had: ▪️ A way to operate reliably under real conditions without breaking, using system-level adaptive multiagent autonomous control. This is what makes scaling quantum possible. This is what makes computing under quantum entanglement possible. ➡️ The current state of Quantum doesn’t fail because of the physics ➡️ It fails because there is no adaptive control layer governing it 🔸🔸 And that’s what we just demonstrated with Seed IQ. What Seed IQ demonstrated is that stability in quantum systems does not have to emerge solely from better hardware or more complex encoding schemes. It can be actively enforced at the system level, in real time, under real-world conditions. And it changes the economics of quantum entirely. The implications of this — and what these results establish as a new benchmark for quantum system performance — become clear when evaluated in direct comparison with current state-of-the-art quantum error correction approaches. This article included a detailed execution summary of the hardware runs by my partner and Chief Innovations Officer, Denis O., followed by a side-by-side comparison of the latest top QEC achievements in field, including Google's Willow chip. This is the shift from lab-controlled validation → real world quantum compute. ➡️ Seed IQ introduces a new path for quantum computing to scale under real hardware operating conditions. 🥳 #AIX #SeedIQ #QuantumAI #QuantumComputing #MultiAgentSystems #ActiveInference #Willow AIX Global Innovations

The last two days have seen two extremely interesting breakthroughs announced in quantum computing. There is a long path ahead, but these both point to the potential for dramatically upscaling ambitions for what's possible in relatively short timeframes. The most prominent advance was Microsoft's announcement of Majorana 1, a chip powered by "topological qubits" using a new material. This enables hardware-protected qubits that are more stable and fault-tolerant. The chip currently contains 8 topologic qubits, but it is designed to house one million. This is many orders of dimension larger than current systems. DARPA has selected the system for its utility-scale quantum computing program. Microsoft believes they can create a fault-tolerant quantum computer prototype in years. The other breakthrough is extraordinary: quantum gate teleportation, linking two quantum processes using quantum teleportation. Instead of packing millions of qubits into a single machine—which is exceptionally challenging—this approach allows smaller quantum devices to be connected via optical fibers, working together as one system. Oxford University researchers proved that distributed quantum computing can perform powerful calculations more efficiently than classical systems. This could not only create a pathway to workable quantum computers, but also a quantum internet, enabling ultra-secure communication and advanced computational capabilities. It certainly seems that the pace of scientific progress is increasing. Some of the applications - such as in quantum computing - could have massive implications, including in turn accelerating science across domains.

Is this the "Attention Is All You Need" moment for Quantum Computing? Oxford University scientists in Nature have demonstrated the first working example of a distributed quantum computing (DQC) architecture. It consists of two modules, two meters apart, which "act as a single, fully connected universal quantum processor." This architecture "provides a scalable approach to fault-tolerant quantum computing". Like how the famous "Attention Is All You Need" paper from Google scientists introduced the Transformer architecture as an alternative to classical neural networks, this paper introduces Quantum gate teleportation (QGT) as an alternative to the direct transfer of quantum information across quantum channels. The benefit? Lossless communication. But not only communication: computation also. This is the first execution of a distributed quantum algorithm (Grover’s search algorithm) comprising several non-local two-qubit gates. The paper contains many pointers to the future, which I am sure will be pored over by other labs, startups and VCs. I am excited to follow developments in: - Quantum repeaters to increase the distance between modules - Removal of channel noise through entanglement purification - Scaling up the number of qubits in the architecture Amid all the AI developments, this may be the most important innovation happening in computing now. https://lnkd.in/e8qwh9zp

Google Unveils Willow: A Leap Forward in Quantum Computing Google Quantum AI has introduced Willow, a cutting-edge quantum chip designed to address two of the field’s most significant challenges: error correction and computational scalability. Willow, fabricated in Google’s Santa Barbara facility, achieves state-of-the-art performance, marking a pivotal step toward realizing a large-scale, commercially viable quantum computer. It gets way geekier from here – but if you’re with me so far… Exponential Error Reduction Julian Kelly, Director of Quantum Hardware at Google, emphasized Willow’s ability to exponentially reduce errors as the system scales. Utilizing a grid of superconducting qubits, Willow demonstrated a historic breakthrough in quantum error correction. By expanding arrays from 3×3 to 5×5 and then 7×7 qubits, researchers cut error rates in half with each iteration. This achievement, referred to as being “below threshold,” signifies that larger quantum systems can now exhibit fewer errors, a challenge pursued since Peter Shor introduced quantum error correction in 1995. The chip also achieved “beyond breakeven” performance, where arrays of qubits outperformed the lifetimes of individual qubits, which is key to ensuring the feasibility of practical quantum computations. Ten Septillion Years in Five Minutes Willow’s computational capabilities were validated using the Random Circuit Sampling (RCS) benchmark, a rigorous test of quantum supremacy. According to Google’s estimates, Willow completed a task in under five minutes that would take a modern supercomputer ten septillion years—a timescale exceeding the age of the universe. This achievement underscores the rapid, double-exponential performance improvements of quantum systems over classical alternatives. While the RCS benchmark lacks direct commercial applications, it remains a critical indicator of quantum computational power. Kelly noted that surpassing classical systems on this benchmark solidifies confidence in the broader potential of quantum technology. Building Toward Practical Applications Google’s roadmap aims to bridge the gap between theoretical quantum advantage and real-world utility. The team is now focused on achieving “useful, beyond-classical” computations that solve practical problems. Applications in drug discovery, battery design, and AI optimization are among the potential breakthroughs quantum computing could unlock. Willow’s advancements in quantum error correction and computational scalability highlight its transformative potential. As Kelly explained, “Quantum algorithms have fundamental scaling laws on their side,” making quantum computing indispensable for tasks beyond the reach of classical systems. Quantum computing is still years away, but this is an exciting milestone. Considering the remarkable rate of technological improvement we’re experiencing right now, practical quantum computing (and quantum AI) may be closer than we think. -s

Nu Quantum has released a paper this week which significantly accelerates the quantum computing timeline by showing a viable path to commercial quantum computing via 'scale-out' 🦾 👀 These results are a significant haircut to Jensen's 15-year prediction for *very useful* computers 👀 We explore a modular architecture of quantum processing units (QPUs) of intermediate size, networked via a photonic fabric made of qubit-photon interfaces and switches. Flexible entanglement topologies are made possible by the network, enabling the use of error correcting codes (Floquet codes) which require significantly lower physical-to-logical qubit ratios than the surface code. We demonstrate that this error-corrected distributed system is feasible to build, since it tolerates realistic network fidelities and doesn't need all-to-all connectivity. The sort of quantum network we are trailblazing at Nu Quantum. Finally, we demonstrate it's efficient - i.e. you don't need more total qubits that in a monolithic approach in order to introduce networking. This is really significant. The results are timely - with the Willow announcement and others, in 2024 the industry demonstrated for the first time that matter qubits can be high-quality enough for computing. So we now have the building blocks. The only remaining orders-of-magnitude challenge is scaling, from ~100 qubits to 10k-1Ms of qubits... -> Modular scaling via networking together near-term available QPUs shortens the time-to-impact of quantum computing and makes the timeline more predictable, since it moves the problem from an R&D one to a scalable manufacturing engineering & capital resource one (stamp-and-repeat of modules that we already know how to make). So proud of the Nu Quantum Quantum Error Correction team for this fantastic work! Link in comments 🙂
