Entanglement distinctively sets the quantum world apart from its classical counterpart. Many-particle entangled quantum states are created in an exponentially fast speed through a novel physical picture of quantum delocalization on a correlation landscape, the latter is defined in a minimal operator subspace.

We confirm the basic mechanism by simulating the sensor-field dynamics using photon interferometry, and, as a concrete example, demonstrate the enhanced sensing of signals encoded in the setting angle of a wave plate.

A new type of quantum needle model system can relax the requirement for radical pair lifetime by an order of magnitude, and retains a narrow functional window around the geomagnetic field. This provides evidence for identifying the possible physical mechanism for quantum needle in chemical compass model of avian magnetoreception.

We achieve a tenfold coherence time extension by destructive interference of cross-correlated noise, improve control fidelity, and surpass the state-of-the-art sensitivity for high frequency quantum sensing, significantly expanding the applicability of noise protection strategies.
