Transpiling Quantum Circuits using the Pentagon Equation
Christos Aravanis, Georgios Korpas, Jakub Marecek
We consider the application of the pentagon equation in the context of quantum circuit compression. We show that if solutions to the pentagon equation are found, one can transpile…
Iteration Complexity of Variational Quantum Algorithms
Vyacheslav Kungurtsev, Georgios Korpas, Jakub Marecek +1
There has been much recent interest in near-term applications of quantum computers, i.e., using quantum circuits that have short decoherence times due to hardware limitations. Vari…
Globally optimal control of quantum dynamics
Denys I. Bondar, Llorenc Balada Gaggioli, Georgios Korpas +3
Optimization of constrained quantum control problems powers quantum technologies. This task becomes very difficult when these control problems are nonconvex and plagued with dense…
A note on holographic renormalization for non-conformal branes by recursion
Georgios Korpas
We review holographic renormalization for non-conformal branes using the Hamilton-Jacobi formalism. We provide the tools required for the computation of the holographic dictionary,…
Polynomial Matrix Inequalities within Tame Geometry
Christos Aravanis, Johannes Aspman, Georgios Korpas +1
Polynomial matrix inequalities can be solved using hierarchies of convex relaxations, pioneered by Henrion and Lassere. In some cases, this might not be practical, and one may need…
Quantum open system identification via global optimization: Optimally accurate Markovian models of open systems from time-series data
Zakhar Popovych, Kurt Jacobs, Georgios Korpas +2
Accurate models of the dynamics of quantum circuits are essential for optimizing and advancing quantum devices. Since first-principles models of environmental noise and dissipation…
