Quantum Computation with Harmonic Oscillators
Stephen D. Bartlett, Barry C. Sanders, Benjamin T. H. Varcoe +1
By encoding a qudit in a harmonic oscillator and investigating the infinite limit, we give an entirely new realization of continuous-variable quantum computation. The generalized P…
Competition-induced shifts of spectral peaks in photon coincidence spectroscopy
L. Horvath, B. C. Sanders
We show that shifts in locations of two-photon coincidence spectral peaks, for a bichromatically-driven two-level atom passing through a single-mode cavity, are due to competition…
Geometric Phase of Three-level Systems in Interferometry
Barry C. Sanders, Hubert de Guise, Stephen D. Bartlett +1
We present the first scheme for producing and measuring an Abelian geometric phase shift in a three-level system where states are invariant under a non-Abelian group. In contrast t…
Unitary transformations for testing Bell inequalities
S. D. Bartlett, D. A. Rice, B. C. Sanders +2
It is shown that optical experimental tests of Bell inequality violations can be described by SU(1,1) transformations of the vacuum state, followed by photon coincidence detections…
