- Abstract: We present a quantum error correcting code with dynamically generated logical
qubits. When viewed as a subsystem code, the code has no logical qubits.
Nevertheless, our measurement patterns generate logical qubits, allowing the
code to act as a fault-tolerant quantum memory. Our particular code gives a
model very similar to the two-dimensional toric code, but each measurement is a
two-qubit Pauli measurement.

We ask what is the general framework for a quantum error correcting code that is defined by a sequence of measurements.
We develop an algorithm that tracks information about the error syndromes through the protocol and put that together to determine the distance of a dynamical code.

We discuss stabilizer quantum-error correction codes implemented in a single multi-level qudit.
These codes can be customized to the specific physical errors on the qudit, effectively suppressing them.
We demonstrate a Fault-Tolerant implementation on molecular spin qudits, showcasing nearly exponential error suppression with only linear qudit size growth.

A high-fidelity -- though non fault-tolerant -- compilation of this universal gate set is possible thanks to the two-qubit physical rotations.

measurements and beyond [68.8204255655161]
We propose an error correction procedure based on a cellular automaton, the sweep rule, which is applicable to a broad range of codes beyond topological quantum codes.
For simplicity, we focus on the three-dimensional (3D) toric code on the rhombic dodecahedral lattice with boundaries and prove that the resulting local decoder has a non-zero error threshold.
We find that this error correction procedure is remarkably robust against measurement errors and is also essentially insensitive to the details of the lattice and noise model.
