Quantum Sensing and Devices

The ability to precisely measure physical quantities is an ultimate limit in our knowledge of the world and our technological progress. When considering a quantum system, the act of measurement itself modifies the state, thus providing a bound on the achievable precision. On the other hand, exploiting quantum properties of single particles, measurement capability can be pushed far beyond what has previously been possible. Since a quantum state is so easily disturbed, this means that they also have the potential to become extraordinarily sensitive measuring instruments. This field aims to build quantum sensors that achieve the best precision that is allowed by the laws of physics, with an additional focus on making them inexpensive and commercially attractive.
