Maximising Quantum-Computing Expressive Power through Randomised Circuits
Yingli Yang, Zongkang Zhang, Anbang Wang +3
In the noisy intermediate-scale quantum era, variational quantum algorithms (VQAs) have emerged as a promising avenue to obtain quantum advantage. However, the success of VQAs depe…
Shadow-based quantum subspace algorithm for the nuclear shell model
Ruyu Yang, Tianren Wang, Bing-Nan Lu +2
In recent years, researchers have been exploring the applications of noisy intermediate-scale quantum (NISQ) computation in various fields. One important area in which quantum comp…
A resource-efficient quantum-classical hybrid algorithm for energy gap evaluation
Yongdan Yang, Ying Li, Xiaosi Xu +1
Estimating the eigenvalue or energy gap of a Hamiltonian H is vital for studying quantum many-body systems. Particularly, many of the problems in quantum chemistry, condensed matte…
A Herculean task: Classical simulation of quantum computers
Xiaosi Xu, Simon Benjamin, Jinzhao Sun +2
In the effort to develop useful quantum computers simulating quantum machines with conventional computing resources is a key capability. Such simulations will always face limits pr…
Measurement-efficient quantum Krylov subspace diagonalisation
Zongkang Zhang, Anbang Wang, Xiaosi Xu +1
The Krylov subspace methods, being one category of the most important classical numerical methods for linear algebra problems, can be much more powerful when generalised to quantum…
