   - 'Motional degree of freedom of a trapped ion: square-lattice GKP encoding realized with the help of post-selection by Home group \cite{arxiv:1807.01033,arxiv:1907.06478}, followed by realization of reduced form of GKP error correction, where displacement error syndromes are measured to one bit of precision using an ion electronic state \cite{arxiv:2010.09681}. State preparation also realized by Tan group \cite{arxiv:2310.15546}. Universal gate set, including a two-qubit entangling gate, realized by Tan group \cite{arxiv:2409.05455}.'
-  - 'Microwave cavity coupled to superconducting circuits: reduced form of square-lattice GKP error correction, where displacement error syndromes are measured to one bit of precision using an ancillary transmon \cite{arxiv:1907.12487}. Subsequent paper by Devoret group \cite{arxiv:2211.09116} uses reinforcement learning for error-correction cycle design and is the first to go beyond break-even error-correction, with the lifetime of a logical qubit exceeding the cavity lifetime by about a factor of two (see also \cite{arxiv:2211.09319}). See Ref. \cite{arxiv:2111.07965} for another experiment. A feed-forward-free, i.e., fully autonomous protocol has also been implemented by Nord Quantique \cite{arxiv:2310.11400}.'

Qudit encodings with \(q=3,4\) have been realized, with logical error rates also beyond break even \cite{arxiv:2409.15065}.'
   - 'GKP states and homodyne measurements have been realized in propagating telecom light by the Furusawa group \cite{arxiv:2309.02306}.'
   - 'Single-qubit \(Z\)-gate has been demonstrated \cite{arxiv:1904.01351} in the single-photon subspace of an infinite-mode space \cite{arxiv:2310.12618}, in which time and frequency become bosonic conjugate variables of a single effective bosonic mode. In this context, GKP position-state wavefunctions are called Dirac combs or frequency combs.'
