Exploiting Quantum Assertions for Error Mitigation and Quantum Program Debugging
2022 IEEE 40TH INTERNATIONAL CONFERENCE ON COMPUTER DESIGN (ICCD 2022), 124–131.
Event: IEEE 40th International Conference on Computer Design (ICCD) at Olympic Valley, CA, USA on October 23-26, 2022
author keywords: quantum computing; error mitigation; debugging; assertion
TL;DR:
This paper presents the development of quantum assertion schemes and shows how they are used for hardware error mitigation and software debugging, and shows that besides detecting program bugs, dynamic assertion circuits can mitigate noise effects via post-selection of the assertion results.

Not All SWAPs Have the Same Cost: A Case for Optimization-Aware Qubit Routing
2022 IEEE INTERNATIONAL SYMPOSIUM ON HIGH-PERFORMANCE COMPUTER ARCHITECTURE (HPCA 2022), pp. 709–725.
author keywords: quantum computing; compiler optimization; qubit routing
TL;DR:
NASSC (Not All Swaps have the Same Cost) is the first algorithm that considers the subsequent optimizations during the routing step, and optimization-aware qubit routing leads to better routing decisions and benefits subsequent optimizations.

Relaxed Peephole Optimization: A Novel Compiler Optimization for Quantum Circuits
CGO '21: PROCEEDINGS OF THE 2021 IEEE/ACM INTERNATIONAL SYMPOSIUM ON CODE GENERATION AND OPTIMIZATION (CGO), pp. 301–314.
author keywords: quantum computing; peephole optimization
TL;DR:
A novel quantum compiler optimization, named relaxed peephole optimization (RPO) for quantum computers, which leverages the single-qubit state information that can be determined statically by the compiler and extends the approach to optimize the quantum gates when some input qubits are in known pure states.

2021 article
Systematic Approaches for Precise and Approximate Quantum State Runtime Assertion
2021 27TH IEEE INTERNATIONAL SYMPOSIUM ON HIGH-PERFORMANCE COMPUTER ARCHITECTURE (HPCA 2021), pp. 179–193.
author keywords: quantum computing; runtime assertion
TL;DR:
This work proposes two systematic approaches for dynamic quantum state assertion and they can assert a much broader range of quantum states including both pure states and mixed states and introduces the idea of approximate quantumstate assertion for the cases where the programmers only have limited knowledge of the quantum states.

Reliability Modeling of NISQ-Era Quantum Computers
2020 IEEE INTERNATIONAL SYMPOSIUM ON WORKLOAD CHARACTERIZATION (IISWC 2020), pp. 94–105.
author keywords: NISQ quantum computer; reliability model; neural network
TL;DR:
This paper treats the NISQ quantum computer as a black box and derives a reliability estimation model using polynomial fitting and a shallow neural network, and proposes randomized benchmarks with random numbers of qubits and basic gates to generate a large data set for neural network training.
