Predoctoral molecular qubits

PhD Position in Quantum Control of Molecular Qubits

We are seeking a highly motivated candidate with a strong interest in experimental Solid State Physics, Surface Science, or Quantum Nanoscience to pursue PhD research at the Materials Physics Center in collaboration with the Donostia International Physics Center in San Sebastián, Spain.

Project Overview:
Quantum computing platforms such as superconducting circuits, trapped ions, and semiconductor quantum dots present unique benefits and challenges. However, using molecules that integrate several qubits has the possibility of reaching a level of integration and scalability beyond the above techniques. To this aim, our project uses the integration of Electron Spin Resonance (ESR) and Scanning Tunneling Microscopy (STM) for exceptional control over individual spins (single atom), see Ref. [1].

Research Goals:
The PhD project will focus on exploiting the capabilities of ESR-STM with candidates of molecular qubits to advance quantum computing technology. This approach aims to develop sophisticated quantum algorithms and robust quantum systems by utilizing the precise control of ESR-STM and the scalable, adaptable nature of molecular qubits. This integration not only seeks to overcome current limitations in quantum computing but also aims to discover new quantum phenomena, thereby expanding the boundaries of the field.

Candidate Expectations:
The ideal candidate will construct molecular nanostructures, characterize, and control quantum properties using ESR-STM techniques. This project is an excellent opportunity to engage in groundbreaking research that combines advanced technologies to address critical challenges in quantum computing and develop practical applications.

Position Details:
The position is available immediately, with a duration of three to four years. Please submit a statement of interest, a CV with an academic transcript showing obtained marks, and at least one reference with contact details to Prof. Nicolas Lorente at nicolas.lorente at ehu.eus or Dr. Deung-Jang Choi at djchoi at dipc.org.

 

Scheme of an atomic 3-qubit system using three inequivalent qubits, two of them formed by a Ti-Fe pair and one as a single Ti atom under a metallic tip (cone) that is the scanning electrode of the STM. The changes in current as the AC bias shifts its frequency in the microwave regime, lead to clear identification of the spin transitions permitting us to achieve quantum coherent control on the atomic scale.
