Approximating dynamical correlation functions with constant depth quantum circuits
One of the most important quantities characterizing the microscopic properties of quantum systems are dynamical correlation functions. These correlations are obtained by time-evolv...

Unveiling quantum phase transitions from traps in variational quantum algorithms
Understanding quantum phase transitions in physical systems is fundamental to characterize their behaviour at small temperatures. Achieving this requires both accessing good approx...

Efficient and practical Hamiltonian simulation from time-dependent product formulas
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...
