Inequivalent classes of closed three-level systems
Andre B. Klimov, Hubert de Guise, Luis L. Sanchez-Soto
We show here that the and V configurations of three-level atomic systems, while they have recently been shown to be equivalent for many important physical quantities when drive…
From Qubits to Continuous-Variable Quantum Computation
Barry C Sanders, Stephen D. Bartlett, Hubert de Guise
By encoding a qudit in a harmonic oscillator and investigating the d --> infinity limit, we give an entirely new realization of continuous-variable quantum computation. The general…
Quantum Encodings in Spin Systems and Harmonic Oscillators
Stephen D. Bartlett, Hubert de Guise, Barry C. Sanders
We show that higher-dimensional versions of qubits, or qudits, can be encoded into spin systems and into harmonic oscillators, yielding important advantages for quantum computation…
Geometric Phase in SU(N) Interferometry
Hubert de Guise, Barry C. Sanders, Stephen D. Bartlett +1
An interferometric scheme to study Abelian geometric phase shift over the manifold SU(N)/SU(N-1) is presented.
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…
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…
