Cross-Kerr nonlinearity between continuous-mode coherent states and single photons
Cross-Kerr nonlinearity continuous-mode coherent states single photons
2013/7/3
Weak cross-Kerr nonlinearities between single photons and coherent states are the basis for many applications in quantum-information processing. These nonlinearities have so far mainly been discussed ...
Weaving independently generated photons into an arbitrary graph state
Weaving independently generated photons arbitrary graph state
2013/7/3
The controlled-Z ( CZ) operations acting separately on pairs of qubits are commonly adopted in the schemes of generating graph states, the multipartite entangled states for the one-way quantum computi...
Supersensitive measurement of angular displacements using entangled photons
Supersensitive measurement angular displacements entangled photons
2010/11/17
We show that the use of entangled photons having non-zero orbital angular momentum (OAM) increases the resolution and sensitivity of angular-displacement measurements performed using an interferomete...
First Microwave Cavity Experiment Search for Hidden Sector Photons
Hidden sector photon Paraphoton Microwave cavity
2010/3/16
In this proceeding we report the first results of a microwave cavity search for hidden sector photons. Using a pair of isolated resonant cavities we look for `light shining through a wall' from photon...
The Coulomb solution as a coherent state of unphysical photons
Coulomb solution coherent state unphysical photons
2010/3/17
In the context of the problem of what micro-states are responsible for the entropy of black holes, we consider as a physical toy model the electromagnetic Coulomb solution. By quantizing the electroma...
