Quantum error correction with dissipatively stabilized squeezed-cat qubits
Quantum error correction with dissipatively stabilized squeezed-cat qubits
Noise-biased qubits are a promising route toward significantly reducing the hardware overhead associated with quantum error correction. The squeezed-cat code, a nonlocal encoding in phase space based on squeezed coherent states, is an example of a noise-biased (bosonic) qubit with exponential error bias. Here we propose and analyze the error …
