One-step implementation of a Toffoli gate of separated superconducting qubits via quantum Zeno dynamics

Based on the quantum Zeno dynamics, a scheme is presented to implement a Toffoli gate of three separated superconducting qubits (SQs) by one step. Three separated SQs are connected by two resonators. The scheme is insensitive to the resonator decay because the Zeno subspace does not include the state of the resonators being excited. Numerical simulations indicate that the scheme is robust to the fluctuation of the parameters and the Toffoli gate can be implemented with high fidelity.     

基于 ATE 的 FPGA 器件测试方案研究磁

在 FPGA 器件的测试领域,由于通用 ATE 的局限性,需要为 ATE 设计 FPGA 配置板。然而目前行业内通用的配置方案测试效率低、可移植性差,给 FPGA 器件测试程序的开发和测试都带来了很多不便。论文提出了一种新的 FP‐GA 多重自动配置技术,设计采用 FPGA 作为主控制器,大容量 FLASH 芯片用于存储目标 FPGA 的配置数据,具有大量存储、调取灵活、配置快速等优点,实现了 Xilinx 公司绝大部分不同型号的 FPGA 器件的多重、自动、快速重配置,有效地解决了原配置方案的弊端,提高了 FPGA 测试的效率。     

Efficient bidirectional quantum secure communication with two-photon entanglement

An efficient bidirectional quantum secure communication protocol is proposed with two-photon entanglement. Compared with the previous protocol proposed by Shi et al., our protocol can achieve higher efficiency. Meanwhile, for the same length secret messages, only half of entangled photon pairs need to be prepared in our protocol. And the number of classical bits in public classical communication is also a half of that in the previous protocol. Moreover, the information leakage does not exist in our scheme.
