Mach–Zehnder interferometer delayed choice quantum eraser Elitzur–Vaidman bomb tester interfere double-slit experiment quantum entanglement linear algebra differential equations
The Mach–Zehnder interferometer (MZI) illustrates the concepts of superposition and interference with linear algebra in dimension 2, rather than differential equations. It can be seen as a simplified version of the double-slit experiment, but it is of interest in its own right, for example in the delayed choice quantum eraser, the Elitzur–Vaidman bomb tester, and in studies of quantum entanglement.
