ExtraFerm: An Extended Matchgate Simulator
Zack Hassman, Oliver Reardon-Smith, Gokul Subramanian Ravi +2
We present and open source Extraferm, a quantum circuit simulator tailored to chemistry applications. More specifically, our simulator can compute the Born-rule probabilities of sa…
Universal Dynamics with Globally Controlled Analog Quantum Simulators
Hong-Ye Hu, Abigail McClain Gomez, Liyuan Chen +6
Analog quantum simulators with global control fields have emerged as powerful platforms for exploring complex quantum phenomena. Despite these advances, a fundamental theoretical q…
Noisy Quantum Simulation Using Tracking, Uncomputation and Sampling
Siddharth Dangwal, Tina Oberoi, Ajay Sailopal +2
Quantum computers have rapidly improved in scale and fidelity, yet access to large systems remains limited for most researchers. This makes accurate and scalable noisy quantum simu…
Variational Quantum Algorithms in the era of Early Fault Tolerance
Siddharth Dangwal, Suhas Vittal, Lennart Maximillian Seifert +2
Quantum computing roadmaps predict the availability of 10,000 qubit devices within the next 3-5 years. With projected two-qubit error rates of 0.1%, these systems will enable certa…
Predictive Window Decoding for Fault-Tolerant Quantum Programs
Joshua Viszlai, Jason D. Chadwick, Sarang Joshi +3
Real-time decoding is a key ingredient in future fault-tolerant quantum systems, yet many decoders are too slow to run in real time. Prior work has shown that parallel window decod…
Demonstration of a CAFQA-bootstrapped Variational Quantum Eigensolver on a Trapped-Ion Quantum Computer
Qingfeng Wang, Liudmila Zhukas, Qiang Miao +5
To enhance the variational quantum eigensolver (VQE), the CAFQA method can utilize classical computational capabilities to identify a better initial state than the Hartree-Fock met…
Clifford Assisted Optimal Pass Selection for Quantum Transpilation
Siddharth Dangwal, Gokul Subramanian Ravi, Lennart Maximilian Seifert +3
The fidelity of quantum programs in the NISQ era is limited by high levels of device noise. To increase the fidelity of quantum programs running on NISQ devices, a variety of optim…
