Description

This issue of Microelectronics TOE covers recent developments in quantum communication technology. Innovations profiled include a quantum dot-based single photon emitting chip for QCT by Sparrow Quantum A/S, an optical quantum repeater for long-distance qubit transmission by the University of Toronto, perfect state transfer of qubit in a photonic integrated device by RMIT University, and a quantum photonic interconnect for qubit transmission between multiple chips by University of Bristol.

The Microelectronics TechVision Opportunity Engine (TOE) captures global electronics-related innovations and developments on a weekly basis. Developments are centred on electronics attributed by low power and cost, smaller size, better viewing, display and interface facilities, wireless connectivity, higher memory capacity, flexibility and wearables. Research focus themes include small footprint lightweight devices (CNTs, graphene), smart monitoring and control (touch and haptics), energy efficiency (LEDs, OLEDs, power and thermal management, energy harvesting), and high speed and improved conductivity devices (SiC, GaN, GaAs).

Miniaturization, a move toward lower power consumption, and the need for enhanced features are driving innovations in the electronics sector. Technology focus areas include semiconductor manufacturing and design, flexible electronics, 3D integration/IC, MEMS and NEMS, solid state lighting, advanced displays, nanoelectronics, wearable electronics, brain computer interface, advanced displays, near field communication, and next generation data storage or memory.

Keywords: Quantum communication technology, quantum photonics, qubit transmission, quantum cryptography techniques
