Performance of teleportation-based error correction circuits for bosonic codes with noisy measurements

Understand

Bosonic quantum error-correcting codes offer a viable direction towards reducing the hardware overhead required for fault-tolerant quantum information processing.

• A broad class of bosonic codes, namely rotation-symmetric codes, can be characterized by their phase-space rotation symmetry.
• However, their performance has been examined to date only within an idealistic noise model.
• Here, we further analyze the error-correction capabilities of rotation-symmetric codes using a teleportation-based error-correction circuit.
