A protocol called the "honeycomb code", or generically a "Floquet code", was introduced by Hastings and Haah in \cite{hastings_dynamically_2021}. The honeycomb code is a subsystem code based on the honeycomb lattice with zero logical qubits but such that there exists a schedule for measuring two-body gauge checks leaving enough room at all times for two protected logical qubits. In this work we show a way to introduce boundaries to the system which curiously presents a rotating dynamics but has constant distance and is therefore not fault-tolerant.

A conditional no-go for resource-free magic-axis measurement on a static surface code
Under three stated assumptions, a resource-free static surface-code patch cannot sharply measure the magic axis at polynomial acceptance; it must pay with a resource, leave the dilute regime, or accept exponentially rarely.

Approximate Dynamical Quantum Error-Correcting Codes
The paper constructs approximate dynamical quantum error-correcting codes for amplitude-damping noise, proves uniqueness and robustness of the SDP-optimized encoding, decoding, and check operations, and introduces a t...
