Quantum sensing uses quantum effects to measure physical signals, while related quantum networks can support secure communications. These technologies may enable sensitive measurements and new approaches to protecting information.
Atomic clocks keep time by measuring the resonant frequency of transitions in atoms or ions.
Quantum gravimeters measure gravitational acceleration using quantum systems, commonly through atom interferometry.
Quantum imaging uses quantum properties of light, such as entanglement or photon correlations, to form or improve images.
Quantum key distribution uses quantum states to establish cryptographic keys, while quantum networks connect quantum devices to exchange quantum information or entanglement.
Quantum magnetometers measure magnetic fields using quantum properties of atoms or defects, including nitrogen-vacancy centers in diamond.
Quantum radar uses quantum effects, such as entanglement or quantum illumination, to improve radar detection or imaging.
