NASA’s Jet Propulsion Laboratory is developing the first-ever space-based quantum gravity sensor that uses ultra-cold atoms to detect minute gravitational variations from orbit, potentially revolutionizing how we map Earth’s hidden features and explore distant planets.
Quantum magnetometers leverage quantum particles’ unique properties to detect extremely small magnetic fields, with their ultimate sensitivity limits governed by quantum noise, parameter estimation theory, and energy resolution constraints that help define their true “quantumness.”
Silicon vacancy centers in Silicon Carbide show promise as room-temperature qubits for quantum sensing applications, with researchers demonstrating that simultaneously operating both transitions in the spin-3/2 quartet through a novel duplex qubit scheme doubles the signal contrast and improves sensitivity compared to conventional single-qubit approaches.
Researchers propose a novel quantum sensing protocol that uses in-cavity squeezed states and optimized transient control to mitigate the Rayleigh curse limitation, enabling more sensitive dark matter detection in microwave cavities without requiring non-Gaussian quantum resources that would be incompatible with the strong magnetic fields needed for axion searches.
Using machine learning-optimized quantum locking techniques, scientists have transformed the previously limiting nonlinear Zeeman effect in Earth-field magnetometers into a quantum advantage by stabilizing naturally occurring spin squeezed states, enabling measurements beyond the standard quantum limit.
