HamQASBench: A Hamiltonian-Informed Diagnostic Benchmark for Evaluating Quantum Architecture Search
Jiayang Niu, Akib Karim, Yan Wang +5
Quantum Architecture Search (QAS) automates the design of parameterized quantum circuits for variational quantum algorithms, yet existing benchmarks organize instances by molecular…
A hardware efficient quantum residual neural network without post-selection
Amena Khatun, Akib Karim, Muhammad Usman
We propose a hardware efficient quantum residual neural network which implements residual connections through a deterministic mixture of the identity operation and variational unit…
Fictitious Copy Quantum Error Mitigation
Akib Karim, Harish J. Vallury, Muhammad Usman
Errors are arguably the most pressing challenge impeding practical applications of quantum computers, which has instigated vigorous research on the development of quantum error mit…
Quantum Jacobi-Davidson Method
Shaobo Zhang, Akib Karim, Harry M. Quiney +1
Computing electronic structures of quantum systems is a key task underpinning many applications in photonics, solid-state physics, and quantum technologies. This task is typically…
Symmetry-Checking in Band Structure Calculations on a Noisy Quantum Computer
Shaobo Zhang, Akib Karim, Harry M. Quiney +1
Band crossings in electronic band structures play an important role in determining the electronic, topological, and transport properties in solid-state systems, making them central…
Fast and Noise-aware Machine Learning Variational Quantum Eigensolver Optimiser
Akib Karim, Shaobo Zhang, Muhammad Usman
The Variational Quantum Eigensolver (VQE) is a hybrid quantum-classical algorithm for preparing ground states in the current era of noisy devices. The classical component of the al…
