Project: Quantum engineered states for optical clocks and atomic sensors
The detection of a quantum state can involve the destruction of that state. This law of quantum physics is one factor currently limiting the stability of the new generation of optical atomic clocks, which could redefine the second, the SI unit of time. A potential solution to solve their stability issues is to use quantum entanglement. Entanglement allows two atoms, or ions, to exhibit the same properties as one another without being physically linked. This means that it is possible to observe the state of one of these atoms, or ions, without destroying the state of the other. This project will use techniques based on quantum entanglement to improve the short term stability of optical atomic clocks beyond the current limitations. The results will improve precision spectroscopy based on scalable entanglement and have a direct impact on a wider range of quantum sensors such as accelerometers, gravimeters, gyrometers and magnetometers.
