Multivariable QSP and Bosonic Quantum Simulation using Iterated Quantum Signal Processing
Niladri Gomes, Hokiat Lim, Nathan Wiebe
We provide in this work a form of Modular Quantum Signal Processing that we call iterated quantum signal processing. This method recursively applies quantum signal processing to th…
Nearly-optimal state preparation for quantum simulations of lattice gauge theories
Christopher F. Kane, Niladri Gomes, Michael Kreshchuk
We present several improvements to the recently developed ground state preparation algorithm based on the Quantum Eigenvalue Transformation for Unitary Matrices (QETU), apply this…
A hybrid method for quantum dynamics simulation
Niladri Gomes, Jia Yin, Siyuan Niu +2
We propose a hybrid approach to simulate quantum many-body dynamics by combining Trotter-based quantum evolution with classical dynamic mode decomposition. In quantum simulation, t…
Adaptive variational simulation for open quantum systems
Huo Chen, Niladri Gomes, Siyuan Niu +1
Emerging quantum hardware provides new possibilities for quantum simulation. While much of the research has focused on simulating closed quantum systems, the real-world quantum sys…
Computing the many-body Green's function with adaptive variational quantum dynamics
Niladri Gomes, David B. Williams-Young, Wibe A. de Jong
We present a method to compute the many-body real-time Green's function using an adaptive variational quantum dynamics simulation approach. The real-time Green's function involves…
Adaptive variational quantum minimally entangled typical thermal states for finite temperature simulations
João C. Getelina, Niladri Gomes, Thomas Iadecola +2
Scalable quantum algorithms for the simulation of quantum many-body systems in thermal equilibrium are important for predicting properties of quantum matter at finite temperatures.…
