Lifting connectivity bottlenecks in superconducting quantum processors via enriched native two-qubit gates
Hanyi Wang, Jingzhe Guo, Lijun Sun +17
Limited qubit connectivity is a central architectural constraint in superconducting quantum processors, whose planar layouts require additional gates to mediate interactions betwee…
Efficient Compilation for Hamiltonian Simulation via Global Binary Symplectic Form Simplification
Zhaohui Yang, Yuwei Han, Ruiyun Zhang +4
Hamiltonian simulation is a core quantum workload, underpinning variational quantum algorithms and Trotterized time evolution. Such programs are expressed as Pauli exponential sequ…
Bunny Codes: Broadening Superconducting Quantum Error Correction Capability through Advanced Control Engineering
Runshi Zhou, Xingye Yuan, Linghang Kong +4
Drawing on advances in superconducting qubit control schemes that unlock enriched native gate sets at the hardware level, we systematically examine how harnessing this enlarged phy…
Unifying Qubit Routing Across Diverse Quantum ISAs via Canonical Representation
Zhaohui Yang, Kai Zhang, Xinyang Tian +6
Qubit mapping/routing is a critical stage in compilation for both near-term and fault-tolerant quantum computers, yet existing scalable methods typically impose several times the r…
Optimal Compilation of Syndrome Extraction Circuits for General Quantum LDPC Codes
Kai Zhang, Dingchao Gao, Zhaohui Yang +4
Quantum error correcting codes (QECC) are essential for constructing large-scale quantum computers that deliver faithful results. As strong competitors to the conventional surface…
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…
