POSTSELECTED Meaning and
Definition
-
Postselected is an adjective that refers to the process of selecting or analyzing a quantum system after a specific measurement has been made. In quantum mechanics, the act of measuring a quantum system causes it to collapse into one of its eigenstates, and the outcome of the measurement provides information about it. However, in some situations, it may be of interest to analyze the system in a different way, by considering only those states that satisfy specific conditions after the measurement.
The concept of postselection arises from the fact that quantum systems can exhibit properties such as superposition and entanglement, where their states are not well-defined until they are observed. Postselected processes allow the observer to condition the analysis of the system on specific measurement outcomes, discarding the rest of the results. This process is achieved by applying additional measurements or conditions on the system after the initial measurement has been made.
Postselection is often utilized in quantum physics experiments and theoretical studies to concentrate on specific states or behaviors of the system. It enables researchers to study events that have relatively low probabilities of occurrence, as they can selectively consider events that meet particular criteria. By focusing on the outcomes that satisfy the desired conditions, postselection allows for a more detailed understanding and analysis of quantum systems.
In summary, postselected describes the process of analyzing a quantum system by selectively examining measurement outcomes that meet specific conditions, allowing for a more comprehensive understanding of quantum behaviors and properties.

Etymology of POSTSELECTED
The word "postselected" is derived from the combination of two root words: "post" and "select".
The term "post" comes from the Latin word "post", meaning "after" or "behind". In English, it usually refers to something that occurs after a specific event or position in time, sequence, or location.
The word "select" originates from the Latin word "selectus", which means "chosen" or "picked out". It refers to the act of carefully choosing or picking out something or someone from a group based on certain criteria or preferences.
Therefore, when combined, "postselected" refers to the process of selecting or choosing something or someone after a particular event, position, or condition has been established. In specific contexts, such as quantum mechanics, "postselect" is used to describe a selection or measurement that occurs after a certain state is prepared or obtained in an experiment or calculation.
