论文摘要
争夺是来自黑洞中的信息损失问题引入的概念。在本文中，我们从纯量子信息理论的角度讨论了争夺的效果。我们引入了$ 7 $ Qubit的量子电路，以进行量子传送。结果表明，如果使用最大的拼凑型统一，则传送性可以是完美的。从这个事实来看，我们猜想``争夺的数量与传送的忠诚度成正比''。为了确认猜想，我们介绍了$θ$依赖性部分争夺统一，这将分别减少到$θ= 0 $和$θ=π/ 2 $。然后，我们通过使用Qiskit（版本$ 0.36.2 $）和$ 7 $ QIBIT REAL量子计算机IBM $ \ _ $ OSLO来分析和数值计算平均保真度。最后，我们得出的结论是，根据选择铃铛测量的量子位，我们的猜想可能是真实的或错误。
Scrambling is a concept introduced from information loss problem arising in black hole. In this paper we discuss the effect of scrambling from a perspective of pure quantum information theory. We introduce $7$-qubit quantum circuit for a quantum teleportation. It is shown that the teleportation can be perfect if a maximal scrambling unitary is used. From this fact we conjecture that ``the quantity of scrambling is proportional to the fidelity of teleportation''. In order to confirm the conjecture we introduce $θ$-dependent partially scrambling unitary, which reduces to no scrambling and maximal scrambling at $θ= 0$ and $θ= π/ 2$, respectively. Then, we compute the average fidelity analytically, and numerically by making use of qiskit (version $0.36.2$) and $7$-qibit real quantum computer ibm$\_$oslo. Finally, we conclude that our conjecture can be true or false depending on the choice of qubits for Bell measurement.
