Distilling Magic States in the Bicycle Architecture
Shifan Xu, Kun Liu, Patrick Rall +2
Magic State Distillation is considered to be one of the promising methods for supplying the non-Clifford resources required to achieve universal fault tolerance. Conventional MSD p…
Asymptotically Optimal Depth Fermionic Permutation on 2D Grid Quantum Architecture without Ancillas
Dantong Li, Shifan Xu, Yongshan Ding
Simulating fermionic systems on qubit hardware involves many nonlocal interactions, and efficient routing of these interactions is critical to the overall cost of fermionic simulat…
Solving Constrained Optimization Problems Using Hybrid Qubit-Qumode Quantum Devices
Rishab Dutta, Brandon Allen, Chuzhi Xu +8
Variational Quantum Algorithms (VQAs) provide a promising framework for tackling complex optimization problems on near-term quantum hardware. Here, we demonstrate that hybrid qubit…
Assessing System Capabilities and Bottlenecks of an Early Fault-Tolerant Bicycle Architecture
Kun Liu, Ben Foxman, Gian-Luca R. Anselmetti +1
Early modular fault tolerant quantum computers remain constrained by costly inter-module communication and limited magic state factory service. Understanding such bottlenecks and i…
Co-Designing Error Mitigation and Error Detection for Logical Qubits
Rohan S. Kumar, Takahiro Tsunoda, Sophia H. Xue +3
Near-term quantum workloads demand error management, yet the two lightest-weight techniques, Quantum Error Detection (QED) and Probabilistic Error Cancellation (PEC), have compleme…
Efficient Routing of Quantum LDPC Codes on Programmable 2D Toric Architectures
Kun Liu, Takahiro Tsunoda, Sophia H. Xue +5
Quantum low-density parity-check codes are promising candidates towards scalable fault-tolerant quantum computation. Among these, bivariate bicycle (BB) codes offer superior encodi…
