Dual-path source engineering in integrated quantum optics

A Source for Mesoscopic Quantum Optics

Correlation functions, first introduced by Glauber [1], are one way to characterize photon number statistics. For example, varieties of nonclassicality criteria can be constructed based on second and higher order moments of the electromagnetic field [2, 3]. Such criteria identify nonclassical fields directly from the measured statistics in a loss tolerant way without complicated analysis techni...

On the genesis and evolution of Integrated Quantum Optics

Dual Z-Source Network Dual-Input Dual-Output Inverter

This paper presents a modified nine switch inverter with two inputs and two Z-source networks. This inverter has two DC inputs and two AC outputs. Input DC voltages can be boosted to the required level. Amplitude, frequency and phase of AC output voltages can be controlled, independently. The proposed converter can be used in applications with two unregulated DC sources, which require feeding ...

Engineering integrated photonics for heralded quantum gates

Scaling up linear-optics quantum computing will require multi-photon gates which are compact, phase-stable, exhibit excellent quantum interference, and have success heralded by the detection of ancillary photons. We investigate the design, fabrication and characterisation of the optimal known gate scheme which meets these requirements: the Knill controlled-Z gate, implemented in integrated lase...
