$W_N$和$W_N^d$态的熵锥

The entropy cones of $W_N$ and $W_N^d$ states

Howard J. Schnitzer

摘要:

计算了量子比特的$W_N$态和量子比特的$W_N^d$态的量子熵锥。对于任意的$N$和$d$,这些锥表现为对称化量子熵锥(SQEC)。给出了描述$W_N$状态和$W_N^d$状态的SQEC的有向图模型。所有$N>3$都违反了一夫一妻制互信息(MMI)。

英文摘要:

The quantum entropy cones (QEC) for $W_N$ states of qubits and $W_N^d$ states of qudits are computed. These cones emerge as symmetrized quantum entropy cones (SQEC) for arbitrary $N$ and $d$. Directed graph models are presented which describe the SQEC for $W_N$ states and $W_N^d$ states. Monogamous mutual information (MMI) is violated for all $N>3$.
