分布式学习和多层计算是确保6 G网络中超可靠和低延迟通信（URLLC）的关键因素。从5G URLLC网络中的连接事物到6 G URLLC网络中的连接智能的独特过渡需要超安全的通信，因为有大量的私人数据。然而，在分布式网络中确保严格的6 G URLLC要求沿着用户隐私和数据安全是一项具有挑战性的任务。在本文中，我们设计了一个分布式量子计算协议，执行一个非局域控制的幺正操作的二分输入状态在隐藏和反事实的方式，并将其与匿名量子通信网络。这种分布式协议允许Bob以受控和概率的方式在Alice的量子位上应用任意的单量子位幺正算子，而不会向她透露算子，也不会通过量子信道传输任何物理粒子-称为反事实隐藏远程计算（CCT）。结果表明，CCT协议既不需要预共享纠缠，也不依赖于二体输入态，单量子比特幺正隐形传态是CCT的一种特殊情况。用于CCT的量子电路可以使用（链式）量子芝诺门来实现。如果Alice和Bob的初始复合状态是Bell类型的状态，则该协议通过简化的电路实现而成为确定性的。此外，我们提供了使用CCT协议的量子匿名广播网络的数值例子，并显示了它们在恶意用户存在下的匿名程度。
Distributed learning and multi-tier computing are the key ingredients to ensure ultra-reliable and low-latency communication (URLLC) in 6G networks. The distinct transition from connected things in 5G URLLC networks to connected intelligence in 6G URLLC networks requires ultra-secure communication due to the massive amount of private data. However, it is a challenging task to ensure stringent 6G URLLC requirements along with user privacy and data security in distributed networks. In this paper, we devise a distributed quantum computation protocol to perform a nonlocal controlled unitary operation on a bipartite input state in concealed and counterfactual manner and integrate it with anonymous quantum communication networks. This distributed protocol allows Bob to apply an arbitrary singlequbit unitary operator on Alice’s qubit in a controlled and probabilistic fashion, without revealing the operator to her and without transmitting any physical particle over the quantum channel-called the counterfactual concealed telecomputation (CCT). It is shown that the CCT protocol neither requires the preshared entanglement nor depends on the bipartite input state and that the single-qubit unitary teleportation is a special case of CCT. The quantum circuit for CCT can be implemented using the (chained) quantum Zeno gates. The protocol becomes deterministic with simplified circuit implementation if the initial composite state of Alice and Bob is a Bell-type state. Furthermore, we provide numerical examples of quantum anonymous broadcast networks using the CCT protocol and show their degrees of anonymity in the presence of malicious users.
