IBM has taken a significant step forward in its development of quantum computing technology. The company has announced that it has successfully manufactured two new processors, Loon and Nighthawk, which are designed to enable more efficient use of qubits during computations.
The Loon processor is focused on the architecture that IBM plans to use for hosting error-corrected logical qubits. It features a square grid structure with each qubit having connections to its four closest neighbors, allowing for more efficient use of qubits. The processor also includes long-distance connections between qubits, which will be needed for the specific type of error correction that IBM has committed to.
The Nighthawk processor, on the other hand, is focused on achieving lower error rates and is designed to enable researchers to test algorithms for quantum advantage. It lacks the long-distance connections found in Loon but has been optimized for reduced error rates.
In addition to these new processors, IBM has also launched a GitHub repository that will allow the community to deposit code and performance data for both classical and quantum algorithms. This move is seen as an effort to enable rigorous evaluations of relative performance between different approaches.
While IBM's announcements are notable, they are not without precedent. Oxford Ionics, which was acquired by IonQ, had previously achieved record-low error rates in some qubit operations using trapped ions. However, details about the company's technology were never fully disclosed due to its acquisition.
IonQ has now announced a new record-low error rate for two-qubit gates, greater than 99.99 percent fidelity. This achievement is significant, as it suggests that IonQ's hardware can be used to perform complex operations with high accuracy.
Finally, Quantum Art has collaborated with Nvidia to develop a more efficient compiler for its trapped-ion hardware. The company's approach involves performing gates with much larger collections of ions, which could lead to potential efficiency gains.
Overall, these announcements demonstrate the rapid progress being made in quantum computing technology. From demonstrations of new architectures to efforts to identify cases where quantum hardware has a real edge, researchers and companies are pushing the boundaries of what is possible.

I'm thinking, IBM's new processors are like Lego blocks for quantum computers - they're trying to build up the right foundation so they can make breakthroughs. The Loon one seems like it could be super useful for error correction, but at the same time, Nighthawk is all about precision and testing algorithms. Meanwhile, IonQ just keeps pushing those error rates down, it's like they're in some kinda quantum competition 
. And then there's Quantum Art working with Nvidia, that sounds like a game-changer - more efficient compilers could make all the difference. I'm curious to see how these advancements will play out in real-world applications 
.
IBM's Loon & Nighthawk processors are pretty cool I guess. The idea of using long-distance connections for error correction in Loon sounds like a good move 
But, let's be real, we're still talking about qubits and their limitations here. We need to see some actual results before we can get too excited 
Still, it's progress and all that...
IBM's Loon processor sounds super useful for hosting error-corrected logical qubits, but have they thought about scalability? Like, can we get to a point where we're not just talking about 2-4 connected qubits and moving up from there?
IBM just said they made 2 new quantum processors lol what's the point if we still need like a million more qubits to make it usable 
also did you see that IonQ beat their own record low error rate? yeah right, and I'm sure NASA's new Mars rover will get there first
