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, any changes in entanglement can be attributed to a succession of avoided energy level crossings at which eigenvalues swap their eigenvecto…
