Abstract

We report an experiment on preparing general four-dimensional quantum states (ququart) using ultrafast-pumped frequency-nondegenerate spontaneous parametric down-conversion. All possible single-ququart states (mixed, pure, and intermediate states) can be prepared in our scheme.

Preparation and characterization of arbitrary states of four-dimensional qudits based on biphotons

So-Young Baek, Stanislav S. Straupe, Alexander P. Shurupov +2 more

We report interferometric schemes to prepare arbitrary states of four-dimensional qudits (ququarts) based on biphoton states of ultrafast-pumped frequency-nondegenerate spontaneous parametric down conversion. Preparation and tomographic characterization of a few examples of general single-ququart states, a pure state, a mixed state (fully diagonal), and a mixed state (partially coherent), are experimentally demonstrated.

Biphoton ququarts and their entanglement

Yoon-Ho Kim

A four-dimensional quantum system (ququart) can be constructed by using the biphoton polarization states of frequency-nondegenerate spontaneous parametric down-conversion. We first discuss how to generate and characterize general single-ququart states with varying degrees of mixedness. We then discuss schemes to entangle multiple biphoton ququarts using linear optics and coincidence post-selection.

Generating entangled states of two ququarts using linear optical elements

So-Young Baek, Yoon-Ho Kim

We propose linear-optical schemes for generating entangled-states of two ququarts (four-dimensional quantum systems) in which single-ququart states are constructed with frequency-nondegenerate biphoton polarization states of spontaneous parametric down-conversion. The schemes require beamsplitters and coincidence post-selection.

Generating entangled states of two ququarts using linear optical elements

So-Young Baek, Yoon Ho Kim

We propose linear optical schemes for generating entangled states of two ququarts (four-dimensional quantum systems) in which the single-ququart state is constructed with frequency-nondegenerate biphoton polarization states of spontaneous parametric down-conversion. We show explicitly that it is possible to generate various two-ququart entangled states by interfering two ququarts at a linear optical beam splitter (an ordinary 50-50 beam splitter, a polarizing beam splitter, or a dichroic beam splitter).

Generating entangled states of two ququarts using linear optical elements

So-Young Baek, Yoon-Ho Kim

Recently, quantum systems with D-dimensional bases states (D > 2) or quDits have attracted much attention in the context of fundamental tests of quantum theory and potential applications in quantum information. In this paper, we discuss several schemes for generating entangled states of two ququarts (four-dimensional quantum systems). The ququart in our scheme is based on frequency-nondegenerate biphoton states of spontaneous parametric down-conversion and we show how the entangled states between two ququarts can be generated with simple linear optical elements, such as an ordinary 50/50 beamsplitter, a polarizing beamsplitter, or a dichroic beamsplitter. We also show that our scheme is capable of generating postselection-free two-ququart entangled states efficiently.
