Quantum computing stands at the frontier of technological advancement, combining physics, engineering, and computer science. While simulation-first research emphasizes theoretical validation through classical computation before hardware implementation, experiment-first quantum research….
1. Introduction: The Need for Advanced Navigation Navigation systems are at the heart of many technologies today — from aircraft and submarines to smartphones and autonomous vehicles. Traditional navigation relies….
1. Introduction to Quantum Metrology Quantum metrology is a subfield of quantum physics that focuses on using quantum properties — like entanglement, superposition, and squeezing — to measure physical quantities….
Quantum technologies are revolutionizing the way we measure, detect, and sense our physical world. At the heart of this revolution lies the concept of quantum noise reduction, which has enabled….
Measurement is a fundamental process in science. Whether you’re detecting gravitational waves, measuring magnetic fields, or determining time with atomic clocks—precision matters. However, classical measurement methods have limits, particularly due….
In both classical and quantum physics, we often want to estimate unknown parameters that describe physical systems. For example: Estimating such parameters is essential in science and engineering — particularly….
In classical physics, measuring something doesn’t change it. You can check the temperature of water or the position of a car without disturbing them. But in quantum mechanics, measurement is….
Feedback control is a universal concept in both classical and quantum systems. It refers to a process where a system’s current behavior is measured, and those results are used to….
Metrology is the science of measurement. It focuses on how accurately we can measure physical quantities—like time, length, mass, temperature, etc. Quantum metrology, on the other hand, goes beyond the….
Before diving into nonlinear quantum optics, let’s understand nonlinear optics in general. Light usually behaves linearly in most materials—meaning that if you double the input light, you get double the….
