Reconfigurable Quantum Instruction Set Computers for High Performance Attainable on Hardware
Zhaohui Yang, Dawei Ding, Qi Ye +3
The performance of current quantum hardware is severely limited. While expanding the quantum ISA with high-fidelity, expressive basis gates is a key path forward, it imposes signif…
Efficient initialization of fluxonium qubits based on auxiliary energy levels
Tenghui Wang, Feng Wu, Fei Wang +13
Fast and high-fidelity qubit initialization is crucial for low-frequency qubits such as fluxonium, and in applications of many quantum algorithms and quantum error correction codes…
Native approach to controlled-Z gates in inductively coupled fluxonium qubits
Xizheng Ma, Gengyan Zhang, Feng Wu +27
The fluxonium qubits have emerged as a promising platform for gate-based quantum information processing. However, their extraordinary protection against charge fluctuations comes a…
Leakage Benchmarking for Universal Gate Sets
Bujiao Wu, Xiaoyang Wang, Xiao Yuan +2
Errors are common issues in quantum computing platforms, among which leakage is one of the most challenging to address. This is because leakage, i.e., the loss of information store…
Linear Cross Entropy Benchmarking with Clifford Circuits
Jianxin Chen, Dawei Ding, Cupjin Huang +1
With the advent of quantum processors exceeding qubits and the high engineering complexities involved, there is a need for holistically benchmarking the processor to have qua…
Randomized Benchmarking Beyond Groups
Jianxin Chen, Dawei Ding, Cupjin Huang
Randomized benchmarking (RB) is the gold standard for experimentally evaluating the quality of quantum operations. The current framework for RB is centered on groups and their repr…
