Heralded Two-Photon Entanglement from Probabilistic Quantum Logic Operations on Multiple Parametric Down-Conversion Sources
T. B. Pittman, M. M. Donegan, M. J. Fitch +5
An ideal controlled-NOT gate followed by projective measurements can be used to identify specific Bell states of its two input qubits. When the input qubits are each members of ind…
Generation of entangled ancilla states for use in linear optics quantum computing
J. D. Franson, M. M. Donegan, B. C. Jacobs
We describe several different methods for generating the entangled ancilla states that are required for linear optics quantum computing. We show that post-selection can be used in…
High-fidelity quantum logic operations using linear optical elements
J. D. Franson, M. M. Donegan, M. J. Fitch +2
Knill, Laflamme, and Milburn [Nature 409, 46 (2001)] have shown that quantum logic operations can be performed using linear optical elements and additional ancilla photons. Their a…
Perturbation theory for quantum-mechanical observables
J. D. Franson, Michelle M. Donegan
The quantum-mechanical state vector is not directly observable even though it is the fundamental variable that appears in Schrodinger's equation. In conventional time-dependent per…
