 | Quantum State Reductions and the Uncertainty Principle
|
| | | | Measurements are important components in any quantum information processing. According to Bohr and Heisenberg, a measurement was considered to always disturb the measured object with random intervention from the apparatus as described by the uncertainty principle: any measurement of an observable causes a back-action to disturb the conjugate observable. This yields many difficulties in precision measurements such as monitoring free mass position for the purpose of accurate monitoring of a clock [1] or detecting the gravitational wave [2]. |
