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…

Erasing photons from bright squeezed vacuum light via above-threshold ionization

J. Rivera-Dean, T. Rook, G. Singh +4

While the interface between strong-field physics and quantum optics offers a unique regime for combining extreme nonlinearity with quantum optical resources, its potential for gene…

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…

Embedding of a non-Hermitian Hamiltonian to emulate the von Neumann measurement scheme

Gurpahul Singh, Ritesh K. Singh, Soumitro Banerjee

The problem of how measurement in quantum mechanics takes place has existed since its formulation. Von Neumann proposed a scheme where he treated measurement as a two-part process…

Emulating the measurement postulates of quantum mechanics via non-Hermitian Hamiltonian

Gurpahul Singh, Ritesh K. Singh, Soumitro Banerjee

Ever since the formulation of quantum mechanics, there is very little understanding of the process of the collapse of a wavefunction. We have proposed a dynamical model to emulate…
