Entanglement Cost of Antisymmetric States and Additivity of Capacity of Some Quantum Channel
Abstract
We study the entanglement cost of the states in the contragredient space, which consists of (d-1) d-dimensional systems. The cost is always 2 (d-1) ebits when the state is divided into bipartite d (d)d-2. Combined with the arguments in Matsumoto02, additivity of channel capacity of some quantum channels is also shown.
