It is incredibly dishonest of them to post this without any details about the noise parameters of the system. When reading "127-qubit system" you would expect that you can perform arbitrary quantum computations on these 127 qubits and they would reasonably cohere for at least a few quantum gates. In reality the noise levels are so strong that you can essentially do nothing with them except get random noise results. M…

Basically little more than having a bathtub and claiming you've built a computer that does 600e23 node fluid dynamic calculations. But a lot more expensive.

For me, the name 'Eagle' reminds me of the book "Soul of a New Machine" by Tracy Kidder. That book is about the design and bring-up of another new (at the time) computer system, the Data General MV/8000, which was also code-named Eagle. I wish IBM great success with their work. edit: Clarified that the MV/8000 project was also code-named Eagle.

Haven’t read that yet but I read “House” by him recently and it was quite good

Anyone who wants to evoke the pioneering spirit of the moon landing™ uses the name. I worked on a project codenamed "Eagle" just earlier this year.

Tangential question, what are the areas of technology where we can expect to see substantial progress or breakthroughs within 2030, i.e. what are the most exciting areas to follow and look forward to? Here's my list:

- Nuclear fusion (Helion, ZAP, TAE, Tokamak Energy, CFS, Wendelstein).

- Self-driving cars.

- New types of nuclear fission reactors.

- Spaceflight (SpaceX Starship).

- Supersonic airplanes (Boom).

- Solid state batteries.

- Quantum computing.

- CPUs and GPUs on sub-5nm nodes.

- CRISPR-based therapies.

- Longevity research.

I can avoid thinking that as a species, QC is a bad investment. I think we’re trying just too early, like Charles Babbage. Great idea but the world doesn’t have the tech required.

I think that if they are honest with themselves, most researchers know they won’t see the day QC are a practical reality, but everyone is trying to become the “father of QC”.

I haven't read anything on this one yet, but your analogy fits Google's “quantum supremacy” paper really well, I likes it.

Any idea where one can find qubit lifetimes and gate fidelities? The classical RF engineering behind controlling that many qubits is certainly great, but it is hard to get excited about the "quantumness" without these figures of merit.

You can create a free account at IBM Quantum and peek at the latest calibration data there.

Edit: Only a fraction of the qubits of the 127 qubit system were calibrated when I looked.
