Revisiting semiconductor bulk hamiltonians using quantum computers
Raphael César de Souza Pimenta, A. T. Bezerra·Aug 22, 2022
With the advent of near-term quantum computers, it is now possible to simulate solid-state properties using quantum algorithms. By an adequate description of the system's Hamiltonian, variational methods enable to fetch of the band structure and othe...
Challenges in the Use of Quantum Computing Hardware-Efficient Ansätze in Electronic Structure Theory.
Ruhee D'Cunha, T. Crawford, M. Motta +1 more·Aug 21, 2022
Advances in quantum computation for electronic structure, and particularly heuristic quantum algorithms, create an ongoing need to characterize the performance and limitations of these methods. Here we discuss some potential pitfalls connected with t...
Detection and evaluation of abnormal user behavior based on quantum generation adversarial network
Minghua Pan, Bin Wang, Xiaoling Tao +3 more·Aug 21, 2022
Quantum computing holds tremendous potential for processing high-dimensional data, capitalizing on the unique capabilities of superposition and parallelism within quantum states. As we navigate the noisy intermediate-scale quantum (NISQ) era, the exp...
Quantum algorithm for Wang-Landau sampling
Garrett T. Floyd, D. Landau, M. Geller·Aug 19, 2022
It has been shown that the Metropolis algorithm can be implemented on quantum computers in a way that avoids the sign problem. However, flat histogram techniques are often preferred as they don’t suffer from the same limitations that afflict Metropolis f...
Efficient Parameterised Compilation for Hybrid Quantum Programming
Anna M. Krol, Koen J. Mesman, A. Sarkar +1 more·Aug 16, 2022
Near term quantum devices have the potential to outperform classical computing through the use of hybrid classical-quantum algorithms such as Variational Quantum Eigensolvers. These iterative algorithms use a classical optimiser to update a parameter...
A finite element configuration interaction method for Wigner localization
Xue Quan, Huajie Chen·Aug 16, 2022
The Wigner localization is an electron phase at low densities when the electrons are sharply localized around equilibrium positions. The simulation of the Wigner localization phenomenon requires careful treatment of the many-body correlations, as the...
Towards the simulation of transition-metal oxides of the cathode battery materials using VQE methods
M. Farag, J. Ghosh·Aug 16, 2022
Variational quantum eigensolver (VQE) is a hybrid quantum-classical technique that leverages noisy intermediate scale quantum (NISQ) hardware to obtain the minimum eigenvalue of a model Hamiltonian. VQE has so far been used to simulate condensed matt...
Adaptive POVM implementations and measurement error mitigation strategies for near-term quantum devices
A. Glos, A. Nykanen, Elsi-Mari Borrelli +4 more·Aug 16, 2022
We present adaptive measurement techniques tailored for variational quantum algorithms on near-term small and noisy devices. In particular, we generalise earlier learning to measure strategies in two ways. First, by considering a class of adaptive po...
Exploring the scaling limitations of the variational quantum eigensolver with the bond dissociation of hydride diatomic molecules
Jacob M. Clary, E. Jones, Derek Vigil-Fowler +2 more·Aug 15, 2022
Materials simulations involving strongly correlated electrons pose fundamental challenges to state-of-the-art electronic structure methods but are hypothesized to be the ideal use case for quantum computing. To date, no quantum computer has simulated...
Quantum Bandit With Amplitude Amplification Exploration in an Adversarial Environment
Byungjin Cho, Yu Xiao, Pan Hui +1 more·Aug 15, 2022
The rapid proliferation of learning systems in an arbitrarily changing environment mandates the need to manage tensions between exploration and exploitation. This work proposes a quantum-inspired bandit learning approach for the learning-and-adapting...
Modeling and simulation of a quantum thermal noise on the qubit
F. Chapeau-Blondeau·Aug 15, 2022
Quantum noise or decoherence is a major factor impacting the performance of quantum technologies. On the qubit, an important quantum noise, often relevant in practice, is the thermal noise or generalized amplitude damping noise, describing the intera...

We study the performance and resource usage of the variational quantum factoring (VQF) algorithm for different instance sizes and optimization algorithms. Our simulations show better chance of finding the ground state when using VQE rather than QAOA ...
Time-marching based quantum solvers for time-dependent linear differential equations
Di Fang, Lin Lin, Yu Tong·Aug 14, 2022
The time-marching strategy, which propagates the solution from one time step to the next, is a natural strategy for solving time-dependent differential equations on classical computers, as well as for solving the Hamiltonian simulation problem on qua...
