Effect of light injection on the security of practical quantum key distribution
Liying Han, Yang Li, Hao Tan +7
Quantum key distribution (QKD) based on the fundamental laws of quantum physics can allow the distribution of secure keys between distant users. However, the imperfections in reali…
Verification of a resetting protocol for an uncontrolled superconducting qubit
Ming Gong, Feihu Xu, Zheng-Da Li +20
Quantum resetting protocols allow a quantum system to be sent to a state in the past by making it interact with quantum probes when neither the free evolution of the system nor the…
Genuine 12-qubit entanglement on a superconducting quantum processor
Ming Gong, Ming-Cheng Chen, Yarui Zheng +20
We report the preparation and verification of a genuine 12-qubit entanglement in a superconducting processor. The processor that we designed and fabricated has qubits lying on a 1D…
Control and Readout Software in Superconducting Quantum Computing
Cheng Guo, FuTian Liang, Jin Lin +5
Digital-to-analog converter (DAC) and analog-to-digital converter (ADC) as an important part of the superconducting quantum computer are used to control and readout the qubit state…
Ultra-precision DC source for Superconducting Quantum Computer
Futian Liang, Peng Miao, Jin Lin +6
The Superconducting Quantum Computing (SQC) is one of the most promising quantum computing techniques. The SQC requires precise control and acquisition to operate the superconducti…
Multi-Code-Rate Correction Technique with IR-QC-LDPC: An application to QKD
Kun Cheng, Qiming Lu, Hongbo Xie +3
In this paper, we report an encoding and decoding method for irregular-quasic-cyclic low-density parity-check (IR-QC-LDPC) codes with multi rates. The algorithm is applicable to pa…
A Compact PCI-based Measurement and Control System for Satellite-Ground Quantum Communication
Binxiang Qi, Shubin Liu, Qi Shen +6
Since the 1990s, there has been a dramatic interest in quantum communication. Free-space quantum communication is being developed to ultra-long distance quantum experiment, which r…
A Multi-chain Measurements Averaging TDC Implemented in a 40 nm FPGA
Qi Shen, Shubin Liu, Binxiang Qi +4
A high precision and high resolution time-to-digital converter (TDC) implemented in a 40 nm fabrication process Virtex-6 FPGA is presented in this paper. The multi-chain measuremen…
A Fast Improved Fat Tree Encoder for Wave Union TDC in an FPGA
Qi Shen, Lei Zhao, Shubin Liu +5
Up to the present, the wave union method can achieve the best timing performance in FPGA based TDC designs. However, it should be guaranteed in such a structure that the non-thermo…
