Programmable logic devices in experimental quantum optics

We discuss the unique capabilities of programmable logic devices (PLDs) for experimental quantum optics and describe basic procedures of design and implementation. Examples of advanced applications include optical metrology and feedback control of quantum dynamical systems. As a tutorial illustration of the PLD implementation process, a field-programmable gate array controller is used to stabil...

Programmable logic devices

Advances in programmable logic devices' architectures are making PLDs suitable for a plethora of applications. The devices now find use in state machines and other highly sequential circuits. In the past two years, bipolar PLD operating speeds have doubled, and emerging CMOS PLDs offer four times the circuitry per chip than the older bipolar versions offered. CMOS PLDs also offer lower operatin...

Quantum optics with single quantum dot devices

A single radiative transition in a single-quantum emitter results in the emission of a single photon. Single quantum dots are single-quantum emitters with all the requirements to generate single photons at visible and near-infrared wavelengths. It is also possible to generate more than single photons with single quantum dots. In this paper we show that single quantum dots can be used to generat...

Thermal Testing on Programmable Logic Devices

In this work, an FPGA-oriented temperature monitoring scheme is presented. A control circuit enables a ring-oscillator during a short period and measures its output frequency, a magnitude that is a function of the die temperature. Several sensors have been constructed using Xilinx chips, obtaining sensitivities between 17 kHz per °C and 77 kHz per °C. The characterization of self-heating, match...
