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…

Trajectory-Protected Quantum Computing
Barbara Šoda, Pierre-Antoine Graham, T. Rick Perche +1
We introduce a novel method that simultaneously isolates a quantum computer from decoherence and enables the controlled implementation of computational gates. We demonstrate a quan…

Phase space analysis of Bell inequalities for mixed Gaussian states
Gurpahul Singh, Kelly Wurtz, Eduardo Martín-Martínez
We present a phase space formalism to evaluate Bell inequality violations in continuous variable systems. By doing so we can generalize previous analyses (which have dealt only wit…
