The quantum register is divided into subregisters on a 2D lattice. The interactions between those can be controlled by the distance between the ion strings. The coupling can be relatively strong and is insensitive to electric field noise. We show entanglement between two separate trapping sites.

You have to keep in mind that editors at Quantum need to be experts in the specific field for each submission. A paper on quantum error correction will be handled by an expert in this !

See also the answer from @felixled.bsky.social I am also not speaking in any official manner.

That being said, we need more editors especially for error correction and quantum algorithms to process submissions faster. Quantum is changing the editorial selection process to get more expertise in these fields. If you want to be an editor (or know somebody) let any editor know (for example me).

I agree that this should not take so long. This are the reasons: 1. Editors are volunteering scientists with no spare time. 2. Quantum received over 1000 submissions in 2024 (that is a LOT). 3. The initial editorial screening is equivalent to an assessment from an expert which takes multiple weeks.

Found them. Quite limited selection but here you go: Without Æ-codes

And since @dulwichquantum.bsky.social requests memes with every paper announcement:

without and with Æ-codes:

With this framework it is not only possible to perform cycle based quantum error correction, but we also found a way to continuously correct using dissipation engineering.

We have then developed a complete error correction scheme using check and correction operators that can be implemented in existing quantum logic experiments.

The absorption-emission codes are designed that an absorbed or emitted photon does not carry any information about the encoded state. We find a required hierarchy of timescales that this condition is true. One can thus find logical basis states encoded in a superposition in a single J manifold.

We are considering a simple linear rotor, whose state is defined by two quantum numbers J,m. Interactions with black body radiation follow selection rules and can change J and m by at most one.

Got at least a bit of fresh snow, touring skis, and the reconstructed ACL is holding up!

Thanks for the great talk and the nice discussion!

Yes, please

Starting to catch up with social media. This work has been published in The Journal of Chemical Physics: doi.org/10.1063/5.02...

We look at Steane QEC implementations of repetition and Color codes with multiple syndrome readout cycles. For Color codes, we compare the Steane QEC to flag-based syndrome readout.
