NIST is developing a new project to create atomically precise electronic devices using silicon atoms for quantum computing and simulation. The project aims to fabricate few-atom devices that can operate as coherent qubits or arrayed atomic structures for analog quantum simulation.
Key achievements so far include:
– Developing robust lithography and contact processes for measuring atomically precise devices
– Fabricating and measuring single electron transistors with stable coulomb blockade oscillations
– Demonstrating controlled variation in electronic and quantum properties at the atomic scale
– Creating an artificial molecule by placing silicon atoms one at a time
– Performing the first analog quantum simulations using a 3×3 array of few atom clusters
The project has significant potential to advance the methods for fabricating atom-based Si electronic structures and exploring synthetic quantum materials and many-body quantum physics.
