MAGIC STATE FACTORY CONSTRUCTIONS FOR PRODUCING CCZ AND T STATES

Abstract: methods, systems, and apparatus for producing ccz states and t states. in one aspect, a method for transforming a ccz state into three t states includes obtaining a first target qubit, a second target qubit and a third target qubit in a ccz state; performing a xgate on the third target qubit; performing an x gate on the first target qubit and the second target qubit using the third target qubit as a control; performing a z gate on the first target qubit and the second target qubit using the third qubit as a x axis control; performing a zgate on the third target qubit; and performing a z gate on the first target qubit and the second target qubit using the third qubit as a x axis control to obtain the three t states.
