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…
