- Abstract: This study examines the possibility of finding perfect entanglers for a
Hamiltonian which corresponds to several quantum information platforms of
interest at the present time. However, in this study, we use a superconducting
circuit that stands out from other quantum-computing devices, especially
because Transmon qubits can be coupled via capacitors or microwave cavities,
which enable us to combine high coherence, fast gates, and high flexibility in
its design parameters. There are currently two factors limiting the performance
of superconducting processors: timing mismatch and the limitation of entangling
gates to two qubits. In this work, we present a two-qubit SWAP and a
three-qubit Fredkin gate, additionally, we also demonstrate a perfect adiabatic
entanglement generation between two and three programmable superconducting
qubits. Furthermore, in this study, we also demonstrate the impact of random
dephasing, emission, and absorption noises on the quantum gates and
entanglement. It is demonstrated by numerical simulation that the CSWAP gate
and $W$-state generation can be achieved perfectly in one step with high
reliability under weak coupling conditions. Hence, our scheme could contribute
to quantum teleportation, quantum communication, and some other areas of
quantum information processing.
