In this paper, we define two split weight enumerators for general quantum codes with entanglement assistance, including nonadditive codes. We show that they obey a MacWilliams identity, which allows us to prove algebraic linear programming bounds, such as the Singleton bound, the Hamming bound, and the first linear programming bound. On the other hand, we derive additional constraints on the size...
Simple and friendly operation interface, intelligent calculation, high performance control and driving circuit, and precision and reliable plant are the necessary conditions for intelligent robot design. In this paper, an intelligent algorithm is proposed for the piano robot control with an interactive program and an automatic control code generator. The interactive program of man-machine interface...
In this paper, a new but simple construction of stabilizer codes and related entanglement-assisted quantum error-correcting codes is proposed based on syndrome assignment by classical parity-check matrices. This method turns the construction of quantum stabilizer codes to the construction of classical parity-check matrices satisfying a specific commutative condition. The designed minimum distance...
