The Photon Quantum Communication and Devices group belongs to the Division of Quantum Materials and Devices, and there has been many researchers from University of Oxford, University of Cambridge, Tsinghua University and Chinese Academy of Science, etc. Our group focus on the quantum key distribution and quantum networking, devoting ourselves to implementing the quantum communication in a more practical method.

The main work in our group includes, the secure key generation system in a high speed based on the integrated silicon photonic chip, the common fiber transmission technology to combine the quantum communication and conventional optical communication, Integrated quantum entanglement source with high efficiency, and the practical quantum repeater and the quantum processor.

We are now having three openings for Postdoctoral Research Fellows:

• Postdoctoral Research Fellow on Quantum key distribution system

Quantum key distribution system has been demonstrated many years ago and it is a good direction to produce some valuable and practical product in the field of quantum communication. Currently, the key point is a longer propagation distance, a higher key generation speed, and miniaturization and integration in the system. Our group focuses on the integrated silicon photonic chip, devoting ourselves to build the chip-based system which can generate the secure key more than 1 Mbps. The main work includes,

1, Novel protocol in the quantum key distribution

2, Design the integrated encoding and decoding chip

3, Build the high speed quantum key distribution system in the fibre channel

• Postdoctoral Research Fellow on Quantum entanglement source

Quantum entanglement source plays an important role in the quantum communication network. Currently, the key point is how to obtain the associated photon pairs and correlation counts in a higher rate when the source is with a high visibility, and the miniaturization and integration in the source. Our group focuses on the integrated silicon photonic chip, devoting ourselves to build the chip-based source which can generate the correlated counts more than 1 KHz. The main work includes,

1, Design the integrated silicon photonic chip for the entanglement source

2, Build the test system for the entanglement source and analyze the data

• Postdoctoral Research Fellow on quantum triode

According to the quantum superposition, quantum entanglement and the quantum coherence, the quantum triode can be a switch and an amplifier similar as the traditional triode, and it can also act as a quantum logical gate and a quantum memory, which will play an important role in the field of quantum computing and the quantum networking. Our group focuses on the quantum triode, devoting ourselves to design the quantum network based on the quantum repeater. The main work includes,

1, Design the quantum triode based on the single spin of a quantum dot, and then build the quantum repeater and the quantum processor

2, Simulate the interaction function between the single solid spin and the optical micro-cavity, optical waveguide, and then improve the property of the quantum triode, or investigate the novel quantum optical device

3, Build the attocube system

Requirements:

1.  The candidates should have or will have the PhD degree in the field of quantum information, optical communication, and semiconductor quantum optics.

2.  Excellent communication and coordination ability, work independently, and good English skill.

3.   Experience in the quantum key distribution, quantum entanglement source and the attocube system.
