High-Throughput Normalized Min-Sum Belief Propagation Decoding for Quantum LDPC Codes with Near-Memory Processing
Jeonggeun Seo, Youngsun Han, Leanghok Hour +1
Real-time quantum error correction requires classical decoders to process growing syndrome workloads with low and predictable latency. For quantum low-density parity-check (qLDPC)…
Adaptive Qubit Freezing Enables Robust Graph Partitioning for Divide-and-Conquer QAOA
Sokea Sang, Leanghok Hour, Dongmin Kim +1
Divide-and-conquer variants of the Quantum Approximate Optimization Algorithm (QAOA) provide a promising route for executing combinatorial optimization problems beyond the qubit ca…
Reducing Postselection Overhead in Magic-State Cultivation by In-Patch Multiplexing
Dongmin Kim, Jeonggeun Seo, Aniket Patra +1
Fault-tolerant quantum computing requires high-fidelity logical magic states for implementing non-Clifford operations. Magic-state cultivation provides a lower-overhead route to lo…
Constraint-Optimal Driven Allocation for Scalable QEC Decoder Scheduling
Dongmin Kim, Jeonggeun Seo, Yongtae Kim +1
Fault-tolerant quantum computing (FTQC) requires fast and accurate decoding of Quantum Error Correction (QEC) syndromes. However, in large-scale systems, the number of available de…
Enhancing the Yield of Bucket Brigade Quantum Random Access Memory using Redundancy Repair
Dongmin Kim, Sengthai Heng, Sanghyeon Lee +1
Quantum Random Access Memory (qRAM) is an essential computing element for running oracle-based quantum algorithms. qRAM exploits quantum superposition to access all data stored in…
