Principles of Quantum Optimization for Constrained Problems
Einar Gabbassov, Gurpahul Singh, Achim Kempf
Constrained combinatorial optimization underlies many industrial and technological decision problems. We develop a spectral theory that unifies many quantum optimization algorithms…
Stochastic Schrödinger Equations for Quantum Reverse Diffusion
Einar Gabbassov
The ensemble-averaged dynamics of open quantum systems are typically irreversible. We show that this irreversibility need not hold at the level of individually monitored quantum tr…
Adiabatic Dynamics of Entanglement
Einar Gabbassov, Achim Kempf
We show that, during adiabatic evolution generated by a time-dependent Hamiltonian, any changes in entanglement can be attributed to a succession of avoided crossings in the Hamilt…
Lagrangian Duality in Quantum Optimization: Overcoming QUBO Limitations for Constrained Problems
Einar Gabbassov, Gili Rosenberg, Artur Scherer
We propose an approach to solving constrained combinatorial optimization problems based on embedding the concept of Lagrangian duality into the framework of adiabatic quantum compu…
Transit facility allocation: Hybrid quantum-classical optimization
Einar Gabbassov
An essential consideration in urban transit facility planning is service efficiency and accessibility. Previous research has shown that reducing the number of facilities along a ro…
