Theoretical Analyses of Quantum Counting against Decoherence Errors
Jun Hasegawa, Fumitaka Yura
In this paper, we analyze the quantum counting under the decoherence, which can find the number of solutions satisfying a given oracle. We investigate probability distributions rel…

Entanglement Cost of Antisymmetric States and Additivity of Capacity of Some Quantum Channel
Keiji Matsumoto, Fumitaka Yura
We study the entanglement cost of the states in the contragredient space, which consists of -dimensional systems. The cost is always ebits when the state…

Entanglement Cost of Three-Level Antisymmetric States
Fumitaka Yura
We show that the entanglement cost of the three-dimensional antisymmetric states is one ebit.
