Experimental quantum computational chemistry with optimised unitary coupled cluster ansatz
Shaojun Guo, Jinzhao Sun, Haoran Qian +35
Quantum computational chemistry has emerged as an important application of quantum computing. Hybrid quantum-classical computing methods, such as variational quantum eigensolvers (…
Experimental Simulation of Larger Quantum Circuits with Fewer Superconducting Qubits
Chong Ying, Bin Cheng, Youwei Zhao +14
Although near-term quantum computing devices are still limited by the quantity and quality of qubits in the so-called NISQ era, quantum computational advantage has been experimenta…
Realization of fast all-microwave CZ gates with a tunable coupler
Shaowei Li, Daojin Fan, Ming Gong +29
The development of high-fidelity two-qubit quantum gates is essential for digital quantum computing. Here, we propose and realize an all-microwave parametric Controlled-Z (CZ) gate…
The Miniature Optical Transmitter and Transceiver For the High-Luminosity LHC (HL-LHC) experiments
Chonghan Liu, Xiandong Zhao, Jinghong Chen +12
We present the design and test results of the Miniature optical Transmitter (MTx) and Transceiver (MTRx) for the high luminosity LHC (HL-LHC) experiments. MTx and MTRx are Transmit…
Component Prototypes towards a Low-Latency, Small-form-factor Optical Link for the ATLAS Liquid Argon Calorimeter Phase-I Trigger Upgrade
Binwei Deng, Mengxun He, Jinghong Chen +14
This paper presents several component prototypes towards a low-latency, small-form-factor optical link designed for the ATLAS Liquid Argon Calorimeter Phase-I trigger upgrade. A pr…
Realization of an Error-Correcting Surface Code with Superconducting Qubits
Youwei Zhao, Yangsen Ye, He-Liang Huang +36
Quantum error correction is a critical technique for transitioning from noisy intermediate-scale quantum (NISQ) devices to fully fledged quantum computers. The surface code, which…
