Quantum metrology is the study of making high-resolution and highly sensitive measurements of physical parameters using quantum theory to describe the physical systems, [1][2][3][4][5][6] particularly exploiting quantum entanglement and quantum squeezing.

2006年1月3日 · We point out a general framework that encompasses most cases in which quantum effects enable an increase in precision when estimating a parameter (quantum metrology). The typical quantum precision enhancement is of the order of the square root of the number of times the system is sampled.

2025年1月18日 · Quantum metrology uses quanta — individual packets of energy — for setting the standards that define units of measurement and for other high-precision research. Quantum mechanics sets the...

2011年3月31日 · Quantum metrology is the use of quantum techniques such as entanglement to yield higher statistical precision than purely classical approaches. In this Review, we analyse some of the...

2024年5月16日 · Quantum sensing and metrology use coherent superposition states of quantum systems to detect and measure physical effects of interest.

Quantum metrology refers to the use of quantum mechanics to enhance sensitivity and resolution in sensing devices, particularly relevant in biology for applications such as biological imaging, sensing, and stimulation.

Welcome to the Frequency Combs & Quantum Metrology Group! This is the web home of the research group of Prof. Scott Diddams. We seek to develop optical measurement tools that lead to new physical understanding and enable technological and scientific breakthroughs.

2024年2月9日 · Critical metrology relies on the precise preparation of a system in its ground state near a quantum phase transition point where quantum correlations get very strong.

2024年11月6日 · As one of the main pillars of quantum technologies, quantum metrology aims to improve measurement precision using techniques from quantum information. The two main strategies to achieve this are the preparation of nonclassical states and the design of optimized measurement observables.

5 天之前 · Quantum effects in metrology can in principle enhance measurement precision from the so-called standard quantum limit to the Heisenberg Limit. Further advancements in quantum metrology largely rely on innovative metrology protocols that can avoid a number of known obstacles, including the challenge of preparing entangled states with sufficient fidelity, the …
