 Counterfactual quantum computation

Counterfactual quantum computation is a fascinating concept that utilizes the principles of quantum mechanics to perform computations in a way that seemingly allows for the computation to occur without actually executing the typical physical operations associated with it. The term "counterfactual" refers to the idea of reasoning about what could have happened under different circumstances, and in this context, it involves analyzing quantum states and their interactions in a manner that does not require the actual execution of all the steps involved in a computation.
