GPU-Accelerated Host-Aware Dead-Measurement Detection in Hybrid Quantum--Classical Programs: Full Version
Yanbin Chen, Qunyou Liu, Yu Wang +2
Hybrid programs combine a quantum circuit with a classical host program that consumes measurement outcomes. In such programs, an outcome may be syntactically read by the host but s…
Vectorizing Quantum Control: A RISC-V Vector Extension Architecture for Scalable Qubit Systems
Xiaorang Guo, Kun Qin, Yanbin Chen +2
The Quantum Control Processor (QCP) bridges the gap between compiler toolchains and control electronics, and is responsible for translating compiled quantum circuits into executabl…
A Quantum Algorithm with Polylogarithmic Depth per Trotter Step for the Extended Hubbard Model
Yu Wang, Martina Nibbi, Maxine Luo +4
The extended Hubbard model on a two-dimensional lattice captures key physical phenomena, but its simulation remains challenging because long-range interactions give rise to a large…
MCMit: Hardware-Software Co-Design for Mid-Circuit Measurement Error Mitigation
Emmanouil Giortamis, Felix Gust, Aleksandra Świerkowska +8
Distributed Quantum Computing (DQC) and Quantum Error Correction (QEC) rely on dynamic circuits that include Mid-Circuit Measurements (MCMs) and classical feedback. These operation…
Branch-Aware Quantum Constant Propagation for Dynamic Quantum Circuits
Innocenzo Fulginiti, Yanbin Chen
Compile-time optimization is important for improving the efficiency and reliability of quantum circuits on current noisy hardware. While many existing methods simplify circuits usi…
Compile-Time Simplification of Classically Controlled Operations in Dynamic Circuits
Innocenzo Fulginiti, Yanbin Chen, Christian B. Mendl +1
Dynamic circuits use real-time outcomes of mid-circuit measurements, processed by a classical controller, to adapt subsequent operations during circuit execution. This additional f…
