About the project
This project will investigate a novel nano-opto-electro-mechanical (NOEM) qubit that has been realised on a nanoscale suspended beam, controlled electrically and read out via optical interaction.
A novel nano-opto-electro-mechanical (NOEM) qubit is proposed to bridge the gap between quantum computing and communication hardware. Mechanically-isolated NOEM qubits can transfer quantum information from charge to light within longer decoherence time. Design optimisation, device fabrication and low temperature measurements are planned to prove the benefit of the NOEM qubits.
Thanks to mechanical isolation of NOEM qubits from the materials surrounded, longer decoherence time is expected. Via optical detection of the quantum state of NOEM qubits, quantum information on the mechanical suspended beam can be transferred efficiently into photon that is used for secure information transfer via quantum communication.
What will be targeted within the PhD period:
- starting from the design of a single NOEM qubit;
- proof of principle of quantum information transfer between charge to photon on a NOEM qubit;
- a demonstration of CNOT operation on double NOEM qubits on silicon nanobeams.
The research is aiming to fill the gap between two main quantum technology themes, quantum computation and quantum communication.
Quantum computing is mainly performed via qubits on solid state media, while photon is a principal carrier of information in quantum communication.
Successful development of NOEM qubits in this project will be able to demonstrate an on-chip solution of quantum information transfer between different media, leading to establish a solid basis of highly-integrated quantum computing and communication systems in future.
