Abstract: A customized low-noise signal read-out circuit, which is designed for the implementation of the integrated low power consumption quantum magnetometers based on nitrogen-vacancy centers in diamond, is reported in this article. As the circuit has a 3.7 pA/Hz1/2 low-input noise which is superior to the latest studies, the integrated quantum diamond magnetometer can achieve […]
Quantum key distribution (QKD) provides a secure method to exchange encrypted information between two parties in a quantum communication infrastructure (QCI). The primary challenge in deploying a QCI is the cost of using optical fibers and trusted repeater nodes (TRNs). Practical systems combine quantum and classical channels on the same fiber to reduce the cost […]
In order to meet mobile cellular users’ ever-increasing data demands, today’s 4G and 5G wireless networks are designed mainly with the goal of maximizing spectral efficiency. While they have made progress in this regard, controlling the carbon footprint and operational costs of such networks remains a long-standing problem among network designers. This article takes a […]
