A major goal of present day physics research is to break the ground for a transition to technologies that harness the full power of the quantum superposition principle and quantum entanglement. While there are still enormous challenges in this respect, we have nevertheless seen exponential increase in stability of quantum devices that are built using superconducting circuits over the past decade, propelling this platform to a leading quantum technology that generates enormous attention in academia and has attracted great investments from industry. For future quantum technology built from modular component, it is essential to have quantum equivalents of classical electronic components. However, in spite of these riveting developments, there is still no ‘quantum equivalent’ of the transistor in superconducting circuits.
In this project we want to realize the first ever quantum spin transistor using a superconducting circuit. There are many unexplored opportunities with smaller systems that are directly applicable to state-of-the-art experiments that typically have a small number of qubits. In addition, it is clear that small optimized devices necessarily yield the best starting point for building larger quantum networks.
