Approximating dynamical correlation functions with constant depth quantum circuits
Reinis Irmejs, Raul A. Santos
One of the most important quantities characterizing the microscopic properties of quantum systems are dynamical correlation functions. These correlations are obtained by time-evolv…
How pure can we go with adiabatic state manipulation?
Raul A. Santos, Alex Kamenev, Yuval Gefen
Dissipative systems with decoherence free subspaces, a.k.a. dark spaces (DSs), can be used to protect quantum information. At the same time, dissipation is expected to give rise to…
Unveiling quantum phase transitions from traps in variational quantum algorithms
Chenfeng Cao, Filippo Maria Gambetta, Ashley Montanaro +1
Understanding quantum phase transitions in physical systems is fundamental to characterize their behavior at low temperatures. Achieving this requires both accessing good approxima…
Efficient and practical Hamiltonian simulation from time-dependent product formulas
Jan Lukas Bosse, Andrew M. Childs, Charles Derby +3
In this work we propose an approach for implementing time-evolution of a quantum system using product formulas. The quantum algorithms we develop have provably better scaling (in t…
Enhancing density functional theory using the variational quantum eigensolver
Evan Sheridan, Lana Mineh, Raul A. Santos +1
Quantum computers open up new avenues for modelling the physical properties of materials and molecules. Density Functional Theory (DFT) is the gold standard classical algorithm for…
