Improving Quantum Circuit Synthesis with Machine Learning

no code implementations9 Jun 2023 Mathias Weiden, Ed Younis, Justin Kalloor, John Kubiatowicz, Costin Iancu

In the Noisy Intermediate Scale Quantum (NISQ) era, finding implementations of quantum algorithms that minimize the number of expensive and error prone multi-qubit gates is vital to ensure computations produce meaningful outputs.

SlimFit: Memory-Efficient Fine-Tuning of Transformer-based Models Using Training Dynamics

no code implementations29 May 2023 Arash Ardakani, Altan Haan, Shangyin Tan, Doru Thom Popovici, Alvin Cheung, Costin Iancu, Koushik Sen

This allows SlimFit to freeze up to 95% of layers and reduce the overall on-device GPU memory usage of transformer-based models such as ViT and BERT by an average of 2. 2x, across different NLP and CV benchmarks/datasets such as GLUE, SQuAD 2. 0, CIFAR-10, CIFAR-100 and ImageNet with an average degradation of 0. 2% in accuracy.

Constant-Depth Circuits for Dynamic Simulations of Materials on Quantum Computers

1 code implementation12 Mar 2021 Lindsay Bassman, Roel Van Beeumen, Ed Younis, Ethan Smith, Costin Iancu, Wibe A. de Jong

Current algorithms for Hamiltonian simulation, however, produce circuits that grow in depth with increasing simulation time, limiting feasible simulations to short-time dynamics.

QGo: Scalable Quantum Circuit Optimization Using Automated Synthesis

no code implementations17 Dec 2020 Xin-Chuan Wu, Marc Grau Davis, Frederic T. Chong, Costin Iancu

Quantum circuit synthesis is a process of decomposing an arbitrary unitary into a sequence of quantum gates, and can be used as an optimization tool to produce shorter circuits to improve overall circuit fidelity.
