Error-Corrected QRAM Queries with One-Fault-Tolerant \texttt{CSWAP} Gates
Shifan Xu, Connor T. Hann, Nathan Wiebe +2
Quantum random-access memory (QRAM) enables coherent queries to classical data. However, the \(O(N)\) qubits required for a memory with \(N=2^n\) addresses make QRAM appear vulnera…
OQRAM: Oblivious Quantum Random Access Memory for Securing Delegated Quantum Queries
Shifan Xu, Yizhuo Tan, Yongshan Ding +1
Quantum query is a basic subroutine in many quantum algorithms, and Quantum Random Access Memory (QRAM) provides a natural way to realize such coherent query access. In delegated s…
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…
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…
In-Situ Simultaneous Magic State Injection on Arbitrary CSS qLDPC Codes
Kun Liu, Shifan Xu, Tomas Jochym-O'Connor +3
Quantum low-density parity-check (qLDPC) codes can encode many logical qubits within a single code block at low physical qubit overhead, yet magic state injection into such codes r…
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…
FTCircuitBench: A Benchmark Suite for Fault-Tolerant Quantum Compilation and Architecture
Adrian Harkness, Shuwen Kan, Chenxu Liu +10
Realizing large-scale quantum advantage is expected to require quantum error correction (QEC), making the compilation and optimization of logical operations a critical area of rese…
