Our results on single molecule spectroscopy have been published. This has been one of the major goals of our lab @uniinnsbruck.bsky.social ! A more detailed summary is given on our website: www.quantum-molecules.eu The full text is available open access at: www.nature.com/articles/s41...

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. journals.aps.org/prx/abstract...

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

All the basic physics and implementation details: quantum-journal.org/papers/q-202... Join us if you want to make molecular quantum error correction reality www.quantum-molecules.eu 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!

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.
