Quantum Polarization Codes for Capacity-Achieving in Discrete Memoryless Quantum Channel
Da Zu Huang, Zhi‐Gang Chen, Xin Li, Ying Guo · Applied Mechanics and Materials · 2010
Quantum channel combining and splitting, called quantum channel polarization, is suggested to design qubit sequences that achieve the symmetric capacity for any given discrete memoryless quantum channels. The polarized quantum channels can be well-conditioned for quantum channel codes, through which one need to send data at rate 1 by employing quantum channels with capacity near 1 and at rate 0 by employing the remaining quantum channels.
