Quantum sensor
open-in-new
<p> Within <a href="/facts/Quantum_technology/cp14mdhq">quantum technology</a>, a quantum sensor utilizes properties of quantum mechanics, such as <a href="/facts/Quantum_entanglement/afzslwN0">quantum entanglement</a>, <a href="/facts/Quantum_interference/lI5f78I4">quantum interference</a>, and <a href="/facts/Quantum_state/7jbxd7Dx">quantum state</a> squeezing, which have optimized precision and beat current limits in <a href="/facts/Sensor/RN8SXbjs">sensor technology</a>. The field of quantum sensing deals with the design and engineering of quantum sources (e.g., entangled) and quantum measurements that are able to beat the performance of any classical strategy in a number of technological applications. This can be done with <a href="/facts/Photonics/6UHcPXbq">photonic</a> systems or <a href="/facts/Solid-state_physics/Cmc6hvyR">solid state</a> systems. </p>
