Introduction

Research interest (multi-photon process in the field of quantum information)

As the foundation of quantum information, the preparation of two-particle and multi-particle entangled states is urgently needed. Till now, many systems have been suggested to prepare entanglement, such ...

Introduction

   Our work focuses on the application of SPDC systems in quantum information. We can encode qubit with polarization, momentum, time, path, and so on. We also pay much attention to high dimensional cases. For example, we can encode qutrit with orbital angular momentum (OAM) and qudit with transverse momentum. The following is the simple introduction to our work. <...

Introduction

   Surface plasmon polariton(SPP) is a surface electromagnetic wave coupling to the free electron oscillations in a metal. It can be excited when a light wave strikes a metal film under appropriate conditions. Such SPPs are involved in a wide range of phenomena, including nanoscale optical waveguiding, perfect lensing, extraordinary optical transmission, subwavelength lithography and ultrahigh-sensitivity biosensing. It is also proved experimentally that SPPs are also useful in the investigation of quantum information. We are doing experiments about the quantum optics with SPPs.
