Here is a list of all quantum codes that specify what rate they have.
Name Rate
Alamouti code The only OSTBC with unity rate.
Bacon-Shor code A non-LDPC family of Bacon-Shor codes achieves a distance of \(\Omega(n^{1-\epsilon})\) with sparse gauge operators.
Balanced product code A notable family of balanced product codes encode \(k \in \Theta(n^{4/5})\) logical qubits with distance \(d \in \Omega(n^{3/5})\) for any number of physical qubits \(n\). Additionally, it is known that the code constructed from the balanced product of two good classical LDPC codes over groups of order \(\Theta(n)\) has a constant encoding rate [1].
Binary Golay code The perfect binary Golay code has a rate of \(12/23 = 0.522\). The extended binary Golay code has a rate of \(12/24 = 0.5\).
Binary repetition code Code rate is \(\frac{1}{n}\), code distance is \(n\).
Chuang-Leung-Yamamoto code Code rate is \(\frac{k}{n \log_2(N+1)}\). To correct the loss of up to \(t\) excitations with \(K+1\) codewords, a code exists with scaling \(N \sim t^3 K/2\).
Color code For general 2D manifolds, \(kd^2 \leq c(\log k)^2 n\) for some constant \(c\) [2], meaning that color codes with finite rate can only achieve an asymptotic minimum distance that is logarithmic in \(n\).
Constant-excitation (CE) code Fock-state CE codes can be used in a protocol that achieves the two-way quantum capacity of the pure-loss Gaussian channel [3].
Convolutional code Depends on the polynomials used. Using puncturing removal [4] the rate for the code can be increased from \(\frac{1}{t}\) to \(\frac{s}{t}\), where \(t\) is the number of output bits, and \(s\) depends on the puncturing done. This is done by deleting some pieces of the encoder output such that the most-likely decoders remain effective
Expander code The rate is \(1 - m/n\) where \(n\) is the number of left nodes and \(m\) is the number of right nodes in the bipartite expander graph.
Expander lifted-product code Expander lifted-product codes include the first examples [5] of (asymptotically) good QLDPC codes, i.e., codes with asymptotically constant rate and linear distance. The existence of such codes proves the QLDPC conjecture [6]. Another notable family encodes \(k \in \Theta(n^\alpha \log n)\) logical qubits with distance \(d \in \Omega(n^{1 - \alpha} / \log n)\) for any number of physical qubits \(n\) and any real parameter \(0 \leq \alpha < 1\) [7].
Fiber-bundle code Rate \(k/n = \Omega(n^{-2/5}/\text{polylog}(n))\), distance \(d=\Omega(n^{3/5}/\text{polylog}(n))\). This is the first QLDPC code to achieve a distance scaling better than \(\sqrt{n}~\text{polylog}(n)\).
Fountain code Random linear fountain codes approach the Shannon limit as the file size \(K\) increases.
Freedman-Meyer-Luo code Codes held a 20-year record the best lower bound on asymptotic scaling of the minimum code distance, \(d=\Omega(\sqrt{n \sqrt{\log n}})\), broken by Ramanujan tensor-product codes.
Goppa code There exist Goppa codes defined over larger alphabets that meet the Gilbert-Varshamov, or GV, bound.
H code The H codes are dense, i.e., the rate \(\frac{k}{k+4}\rightarrow 1\) as \(k \rightarrow \infty\). The distance is 2. However an \(r\)-level concatenation of H codes gives a distance of \(2^r\).
Haar-random code The rate of the code is equal to the coherent information of the channel (i.e. the quantum channel capacity).
Hamming code Asymptotic rate \(k/n = 1-\frac{\log n}{n} \to 1\) and normalized distance \(d/n \to 0\).
Heavy-hexagon code \(1/n\) for a distance-\(d\) heavy-hexagon code on \(n = (5d^2-2d-1)/2\) qubits.
Justesen code

The first asymptotically good codes. Rate is \(R_m=k/n=K/2N\geq R\) and the relative minumum distance satisfy \(\delta_m=d_m/n\geq 0.11(1-2R)\), where \(K=\left\lceil 2NR\right\rceil\) for asymptotic rate \(0<R<1/2\); see pg. 311 of Ref. [8].

The code can be improved and extend the range of \(R\) from 0 to 1 by puncturing, i.e., by erasing \(s\) digits from each inner codeword. This yields a code of length \(n=(2m-s)N\) and rate \(R=mk/(2m-s)N\). The lower bound of the distance of the punctured code approaches \(d_m/n=(1-R/r)H^{-1}(1-r)\) as \(m\) goes to infinity, where \(r\) is the maximum of 1/2 and the solution to \(R=r^2/(1+\log(1-h^{-1}(1-r)))\), and \(h\) is the binary entropy function.

Kitaev surface code Rate depends on the underlying cellulation and manifold. For general 2D manifolds, \(kd^2\leq c(\log k)^2 n\) for some constant \(c\) [2], meaning that (1) 2D surface codes with bounded geometry have distance scaling at most as \(O(\sqrt{n})\) [9][10], and (2) surface codes with finite rate can only achieve an asymptotic minimum distance that is logarithmic in \(n\). Higher-dimensional hyperbolic manifolds (see code children below) yield distances scaling more favorably. Loewner's theorem provides an upper bound for any bounded-geometry surface code [11].
Lifted-product (LP) code There is no known simple way to compute the logical dimension \(k\) in the general case [7].
Linear binary code A family of linear codes \(C_i = [n_i,k_i,d_i]\) is asymptotically good if the asymptotic rate \(\lim_{i\to\infty} k_i/n_i\) and asymptotic distance \(\lim_{i\to\infty} d_i/n_i\) are both positive.
Locally recoverable code (LRC) The rate \(r\) of an \((n,k,r)\) LRC code satisfies \begin{align} \frac{k}{n}\leq\frac{r}{r+1}~. \end{align}
Monitored random-circuit code Rate can be finite [12], depending on the family of random codes generated by the circuit.
Movassagh-Ouyang Hamiltonian code The rate depends on the classical code, but distance can scale linearly with \(n\).
Multi-mode GKP code Transmission schemes with multimode GKP codes achieve, up to a constant-factor offset, the capacity of displacement-noise and thermal-noise Gaussian loss channels [13][14][15][16].
Orthogonal Spacetime Block Code (OSTBC) The greatest rate which can be achieved is \(\frac{n_0+1}{2n_0}\), where either \(n=2n_0\) or \(n=2n_0-1\) [17].
Pastawski-Yoshida-Harlow-Preskill (HaPPY) code The pentagon HaPPY code has an asymptotic rate \(\frac{1}{\sqrt{5}} \approx 0.447\). The pentagon/hexagon HaPPY code, with alternating layers of pentagons and hexagons in the tiling, has a rate of \(0.299\) if the last layer is a pentagon layer and a rate of \(0.088\) if the last layer is a hexagon layer.
Perfect quantum code \(k/n\to 1\) asymptotically with \(n\).
Polar code Supports reliable transmission at rates \(K/N\) approaching the Shannon capacity of the channel.
Projective-plane surface code The rate is \(1/n\), where \(n\) is the number of edges of the particular cellulation.
Quantum Reed-Muller code \(\frac{k}{n}\), where \(k = 2^r - {r \choose t} + 2 \sum_{i=0}^{t-1} {r \choose i}\). Additionally, CSS codes formed from binary Reed-Muller codes achieve channel capacity on erasure channels [18].
Quantum Tanner code Good QLDPC codes.
Quantum expander code \([[n,k=\Theta(n),d=O(\sqrt{n})]]\) code with asymptotically constant rate.
Quantum low-density parity-check (QLDPC) code A family of QLDPC codes \([[n_i,k_i,d_i]]\) is asymptotically good if the asymptotic rate \(\lim_{i\to\infty} k_i/n_i\) and asymptotic distance \(\lim_{i\to\infty} d_i/n_i\) are both positive. The first examples of good qubit codes are a family of lifted-product codes.
Ramanujan-complex product code For 2D Ramanujan complexes, the rate is \(\Omega(\sqrt{ \frac{1}{n \log n} })\), with minimum distance \(d = \Omega(\sqrt{n \log n}) \). For 3D, the rate is \( \Omega(\frac{1}{\sqrt{n}\log n}) \) with minimum distance \(d \geq \sqrt{n} \log n \).
Random code Typical random codes (TRC) or typical random linear codes (TLC) refer to codes in the respective ensemble that satisfy a certain minimum distance. The relative fraction of typical codes in the ensemble approaches one as \(N\) goes to infinity [19] (see also Ref. [20]). Asymptotically, given distance \(d\), the maximum rate for a TRC is given by \(R=\frac{1}{2}R_{GV}(\delta)\) where \(R_{GV}\) is the Gilbert–Varshamov (GV) bound \(R_{GV}=1-h(\delta)\), and \(h(\delta)=h(\frac{d}{n})\) is the binary entropy function. The maximum rate for a TLC is given by \(R=R_{GV}(d)\), meaning that TLCs achieve the asymoptic GV bound.
Rank-modulation code Rank modulation codes with code distance \(d=\Theta(n^{1+\epsilon})\) for \(\epsilon\in[0,1]\) achieve a rate of \(1-\epsilon\) [21].
Reed-Muller (RM) code Achieves capacity of the binary erasure channel [22].
Single parity-check code The code rate is \(\frac{n}{n+1}\to 1\) as \(n\to\infty\). The code distance is 2.
Tanner code For a short code \(C_0\) with rate \(R_0\), the Tanner code has rate \(R \geq 2R_0-1\). If \(C_0\) satisfies the Gilbert-Varshamov bound, the rate \(R \geq \delta = 1-2h(\delta_0)\), where \(\delta\) (\(\delta_0\)) is the relative distance of the Tanner code (\(C_0\)), and \(h\) is the binary entropy function.
Tornado code Come arbitrarily close to the capacity of the binary erasure channel.
Two-dimensional hyperbolic surface code Two-dimensional hyperbolic surface codes have an asymptotically constant encoding rate \( k/n \) with a distance scaling logarithmically with \( n\) when the surface is closed. The encoding rate depends on the tiling \( {r,s} \) and is given by \( k/n = (1-2/r - 2/s) + 2/n \), which approaches a constant value as the number of physical qubits grows. The weight of the stabilizers is \( r \) for \( Z \)-checks and \( s \) for \( X \)-checks. For open boundary conditions, the code reduces to constant distnace.
XYZ product code Not much has been proven about the relationship between XYZ-product codes and other codes. The logical dimension depends on properties of the input classical codes, specifically similarity invariants from abstract algebra. It is conjectured that specific instances of XYZ-product codes have a constant encoding rate and a minimum distance of \(d \in \Theta(n^{2/3})\) [23].
Zetterberg code The rate is given by \(1-\frac{4s}{n}\), which is asymptotically good, with a minimum distance of 5.
