Geometric Aspects of Entanglement Generating Hamiltonian Evolutions
Carlo Cafaro, James Schneeloch
We examine the pertinent geometric characteristics of entanglement that arise from stationary Hamiltonian evolutions transitioning from separable to maximally entangled two-qubit q…
Photonic qubit encoding interconversion for heterogeneous quantum networking
Vedansh Nehra, Richard J. Birrittella, Christopher C. Tison +10
Quantum information processing, communication, and sensing networks are being developed with various qubit platforms that use different encoding schemes. Connecting quantum network…
Lissajous coherent states via projection
Errico J. Russo, James Schneeloch, Edwin E. Hach +3
We construct stationary coherent states concentrated on Lissajous figures of the isotropic and anisotropic harmonic oscillators, the latter having coprime frequencies, by projectin…
Symmetry-Based Perspectives on Hamiltonian Quantum Search Algorithms and Schrodinger's Dynamics between Orthogonal States
Carlo Cafaro, James Schneeloch
It is known that the continuous-time variant of Grover's search algorithm is characterized by quantum search frameworks that are governed by stationary Hamiltonians, which result i…
Efficiency, Curvature, and Complexity of Quantum Evolutions for Qubits in Nonstationary Magnetic Fields
Carlo Cafaro, James Schneeloch
In optimal quantum-mechanical evolutions, motion can take place along paths of minimal length within an optimal time frame. Alternatively, optimal evolutions may occur along establ…
