$IONQ “We leverage the flexibility of a trapped-ion quantum computer to demonstrate nine quantum error-correcting codes with starkly different qubit connectivity requirements on a single device without any hardware reconfiguration. These experiments span three families of quantum error-correcting codes: qLDPC codes, topological codes, and concatenated codes.
With a qLDPC code encoding 4 logical qubits into 18 physical qubits, we achieve a logical error rate up to
9× better than a previous demonstration of a similar code on superconducting solid-state qubits.
Moreover, our implementation exhibits breakeven performance, with some instances achieving qubit lifetimes comparable to or slightly exceeding that of our trapped-ion qubits. We use a novel implementation of the optical-metastable-ground (OMG) architecture for addressable mid-circuit measurement and reset, which enables us to perform these experiments without any ion transport or dedicated coolant ions, requirements that typically consume a large fraction of the runtime or ion count of trapped-ion quantum computers.”
Wow, congratulations to the team at $IONQ!
We’re proud to share our latest advance in fault-tolerant quantum computing using high-rate quantum low-density parity-check (qLDPC) codes, which we have found directly reduce qubit overhead.
With our trapped-ion hardware, we can demonstrate logical qubits with a high encoding rate on a single device, which requires much lower qubit overhead than other popular approaches like the surface code. This result represents substantial progress toward IonQ’s large-scale quantum architecture.
Congratulations to the team who have been working across labs on this research: Edwin Tham, Michael Goldman, Shantanu Debnath, Ashay Patel, Jyothi Saraladevi, Jason Nguyen, Erik Nielsen, Neal Pisenti, Kenneth Wright, John Gamble, and Nicolas Delfosse.

$OKLO is next.
IEA data center electricity demand is set to rise from ~290 TWh today to ~1,200 TWh by 2035, a ~4x increase, with AI-optimized servers driving the majority of incremental load.
The investable implication: power generation, grid infrastructure, and cooling become the binding constraint on AI buildout, not chips. We view this as the early innings of a multi-decade #electrification capex cycle.

The quantum era won't be won by whoever builds the best qubit. It'll be won by whoever owns the entire stack — and almost no one is analyzing the race that way. So I built the analysis that does. "The Quantum Full Stack: Defining the Quantum Tech Era" evaluates the four leading vendors across hardware, cloud, software, fault-tolerance, and networking — every score reproducible, no vendor reviewing a single line.
Why does this matter? Simple: whoever controls the full stack position will control the chess board. And with the quantum tech market maturing faster than expected, this might be critically important to both operators and investors. 120+ pages of primary-sourced analysis on the question the field has been getting wrong. This is the framework the next phase will be measured against.

$IONQ “In a striking demonstration of the method's capabilities, the AI independently rediscovered the textbook circuit for the Quantum Fourier Transform, a fundamental building block of many quantum algorithms, without being told what the solution should look like. This demonstrates the promising use of AI across the quantum computing stack.”
AI is unlocking breakthroughs in quantum computing.
🤝 We collaborated with the University of Innsbruck to tackle a core challenge in building useful quantum supercomputers: automatically designing efficient quantum circuits.
Using NVIDIA CUDA-Q, we built a multimodal diffusion model to synthesize quantum circuits from scratch, optimizing circuit structure and gate parameters simultaneously to produce shorter, lower-error circuits.
💡 The standout result: the AI model independently rediscovered the Quantum Fourier Transform — without being told what the solution should look like.
