2026 Quantum papers! Congratulations Quantum community! It’s hard to believe 10 years have passed and we’re en route to our 10-year founding anniversary in April 2026. On that occasion we wanted to announce ...

Celebrate with us Quantum's approaching 10 year anniversary in 2026 with the publication of the 2026th paper! Do you know which paper that is?

An infographic describing the drain of scientific publishing

In general, let's just stop paying companies that host this BS.

Fight the drain of scientific publishing.

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.

Our paper on 2D connectivity in ion traps has been published. We demonstrate the building blocks of a trapped ion architecture that does not need junctions or ion crystal splitting and merging. This has been a tour de force but it has been worth it.

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.

There is much community knowledge about quantum systems that is hard to find in publications. Silicon is not ideal for ion traps at cryogenic temperatures. We worked with Infineon Austria to develop a fused silica based trap instead of silicon for complex trap designs. arxiv.org/abs/2505.21284

Simulating two-dimensional lattice gauge theories on a qudit quantum computer - Nature Physics Qubit-based simulations of gauge theories are challenging as gauge fields require high-dimensional encoding. Now a quantum electrodynamics model has been demonstrated using trapped-ion qudits, which e...

Hats off to Michael Meth for doing the experiments on this monster project: www.nature.com/articles/s41...

Innsbruck is hosting YAO!!!! Are you not yet registered? Hurry up :-) list of speakers AMAZInG! Honestly, YAO is one of the best event the Atomic Physics community has ever created for PhD Students! @yao2025.bsky.social

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.

Strategies for implementing quantum error correction in molecular rotation Brandon J. Furey, Zhenlin Wu, Mariano Isaza-Monsalve, Stefan Walser, Elyas Mattivi, René Nardi, and Philipp Schindler, Quantum 8, 1578 (2024). The rotation of trapped molecules offers a promising plat...

Our work on quantum error correction in molecular rotation got published in Quantum! quantum-journal.org/papers/q-202...
We were inspired by @vva.bsky.social et al's work on robust encoding of quantum information in quantum rotors.
We developed implementation strategies for Æ-codes in ion traps

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

Demonstration of Fault-Tolerant Steane Quantum Error Correction New results of the performance of Steane error correction in trapped ions demonstrate improved logical fidelities and reveal a competitive approach for fault-tolerant quantum computing.

This has been published in PRX Quantum: doi.org/10.1103/PRXQ...

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

Our first work on molecular ions is on the arxiv! We had a look into the dissociation process of CaOH+. The molecule can be formed by reaction with water molecules. We took a single- and two- photon dissociation spectrum: arxiv.org/abs/2401.10854

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.

Our preprint on Steane QEC is online: arxiv.org/abs/2312.09745 A collaboration of
@uniinnsbruck.bsky.social and FZ Jülich. In Steane QEC, the syndrome readout is performed by preparing additional logical qubits and transversal CNOTs.
