Was Crocodile stronger at Marineford? Or was he holding back in Alabasta?

 During the Alabasta arc, Crocodile displayed a level of power that was initially considered overwhelming by the Straw Hat Pirates. He possessed the Logia-type Devil Fruit called the Suna Suna no Mi (Sand-Sand Fruit), which granted him the ability to control and transform into sand. He had a reputation as a Shichibukai and controlled the desert kingdom of Alabasta from the shadows. His strength was showcased through his battles with Luffy and others. At Marineford, Crocodile was present as part of the war that took place at Marine Headquarters. While he did participate in the battle, he didn't display the same level of dominance as some other powerful characters present. This has led fans to speculate that he might not have been as strong as initially portrayed in Alabasta. It's important to note that power scaling and character abilities can be subject to interpretation and development by the author. Oda often keeps details deliberately open-ended to keep the story intriguing.

Explain quantum computing in simple terms

 Quantum computing is a type of computing that uses the principles of quantum mechanics to perform calculations and operations on data. In classical computing, data is represented by bits, which have a value of either 0 or 1. In quantum computing, data is represented by quantum bits, or qubits, which can have a value of 0, 1, or both at the same time. This allows quantum computers to perform calculations on multiple pieces of data simultaneously, which can make them much faster and more powerful than classical computers for certain types of problems.
