Optimal quantum error- correction codes are necessary to extend the lifetime of quantum memories. A new error- correction code to rectify. too much coherence. We need quantum error correction! ' New class of error correction codes for a bosonic mode'. General binomial code corrects L losses,. A talk by Murphy Niu at the 4th International Conference on Quantum Error Correction, hosted September 11- 15, by Georgia Tech and the. Several proposals have been made for storing error- correctable quantum information in bosonic modes. bosonic QEC codes that are suitable for - interaction based quantum computation: the parity- check code, the embedded error- correcting code. New Class of Quantum Error- Correcting Codes for a Bosonic Mode. approximate quantum error correction to any given order in the time step. A family of bosonic quantum error- correcting codes is introduced to boost the reliability of quantum computation schemes against photon loss. Traditional quantum error- correcting codes are designed for the depolarizing. and for bosonic systems, we consider the qudit amplitude damping channel. Alternatively, logical qubits with bosonic- mode- encoding are of particular interest because their QEC protection is hardware efficient, but gate.
