Maximum speed of quantum gate operation
Lev B. Levitin, Tommaso Toffoli, Zachary Walton
We consider a quantum gate, driven by a general time-dependent Hamiltonian, that complements the state of a qubit and then adds to it an arbitrary phase shift. It is shown that the…

Operation Time of Quantum Gates
Lev B. Levitin, Tommaso Toffoli, Zachary Walton
We consider a quantum gate that complements the state of a qubit and then adds to it an arbitrary phase shift. It is shown that the minimum operation time of the gate is tau = (h/4…
