A Quantum Transistor with Superconducting Qubits

ORAL

Abstract

We show that four qubits with next-to-neighbor Heisenberg interactions works as a spin transistor, i.e. a system with perfect state transfer or perfect blockade depending on the spin state of the system. We also propose how this system can be implemented with state-of-the-art superconducting qubits.
