Optimal experiment design for minimal tomography

Lasers and Electro-Optics/Quantum Electronics and Laser Science Conference: 2010 Laser Science to Photonic Applications, CLEO/QELS 2010 (2010)

Authors:

J Nunn, BJ Smith, G Puentes, JS Lundeen, IA Walmsley

Abstract:

Given an experimental set-up and a fixed number of measurements, how should one take data in order to optimally reconstruct the state of a quantum system? We show how to calculate the optimal design explicitly. © 2010 Optical Society of America.

Phase-controlled photonic quantum circuits in laser written integrated optics

Lasers and Electro-Optics/Quantum Electronics and Laser Science Conference: 2010 Laser Science to Photonic Applications, CLEO/QELS 2010 (2010)

Authors:

N Thomas-Peter, BJ Smith, D Kundys, PGR Smith, IA Walmsley

Abstract:

We present a direct UV-written integrated photonic circuit with on-chip phase control through a thermo-optic phase shifter. An arbitrary beam splitter and a two-photon NOON state are demonstrated with high visibility interference. © 2010 Optical Society of America.
