Quantum State Tomography

Quantum State Tomography is a method used to determine the complete description of a quantum system’s state. Since quantum states are often hidden and not directly observable, scientists perform a series of measurements on many identical copies of the system from different angles. By analyzing these results, they can reconstruct the underlying quantum state, much like piecing together a 3D object from many 2D images. This process helps researchers understand, verify, or manipulate quantum systems for applications like quantum computing and communication.
