Tripartite Frequency-bin-encoded W States on a Chip

Abstract

We introduce an integrated source of genuine tripartite frequency-bin-encoded W states with a predicted generation rate of ∼10 kHz for milliwatt pump powers. We discuss the advantages of this approach compared to others.

Integrated photonic sources of frequency-bin-encoded multipartite entangled states

Milica Banić, John E. Sipe, Marco Liscidini

We demonstrate that genuine multipartite entangled states can be generated using frequency bin encoding in integrated photonic platforms. We introduce a source of four-photon GHZ states and a source of three-photon W states. We predict generation rates on the order of ${10}^{4}$ Hz for a silicon microring source with milliwatt pump powers. These results, along with the versatility and scalability of integrated structures, identify this as a promising approach for the generation of higher-dimensional and larger entangled states.

Photonic multipartite entanglement in discrete variables without arbitrary unitaries

We present an approach for designing sources of postselected multipartite states based on photon-pair sources. Our approach can be applied to arbitrary target states in different encoding schemes and physical platforms. It also allows one to limit the types of components to be used in the device, such that lossy or difficult-to-implement optical elements can be avoided. As an example, we apply this strategy to design a passive integrated source of frequency-bin-encoded high-dimensional GHZ states with a 10-kHz on-chip generation rate for picojoule pump pulses.

We demonstrate that genuine multipartite entangled states can be generated using frequency bin encoding in integrated photonic platforms. We introduce a source of four-photon GHZ states and a source of three-photon W states. We predict generation rates on the order of 104{10}^{4}104 Hz for a silicon microring source with milliwatt pump powers. These results, along with the versatility and scalability of integrated structures, identify this as a promising approach for the generation of higher-dimensional and larger entangled states.
