Spatial Light Modulators to Measure Entanglement Between Spatial States

Abstract

We use Spatial Light Modulators to observe single-photon, non-trivial superpositions of Orbital Angular Momentum (OAM) states. Using the analogy between polarisation and two-dimensional OAM subspaces, we also measure entanglement between these complex modal superpositions.

Entanglement of arbitrary superpositions of modes within two-dimensional orbital angular momentum state spaces

Barry Jack, Alison M. Yao, Jonathan Leach +5 more

We use spatial light modulators (SLMs) to measure correlations between arbitrary superpositions of orbital angular momentum (OAM) states generated by spontaneous parametric down-conversion. Our technique allows us to fully access a two-dimensional OAM subspace described by a Bloch sphere, within the higher-dimensional OAM Hilbert space. We quantify the entanglement through violations of a Bell-type inequality for pairs of modal superpositions that lie on equatorial, polar, and arbitrary great circles of the Bloch sphere. Our work shows that SLMs can be used to measure arbitrary spatial states with a fidelity sufficient for appropriate quantum information processing systems.

Observation of quantum entanglement using spatial light modulators

Eric Yao, Sonja Franke‐Arnold, Johannes Courtial +2 more

We use spatial light modulators to observe the quantum entanglement of down-converted photon pairs. Acting as diffractive optical elements within one of the beams, they can be reconfigured in real time to set the spatial profile of the measured mode. Such configurations are highly applicable to the measurement of orbital angular momentum states or other spatial modes, such as those associated with quantum imaging.

Fourier relationship between the angle and angular momentum of entangled photons

Anand K. Jha, Barry Jack, E. Yao +6 more

We study the Fourier relationship between angle and orbital angular momentum of entangled photons. Spatial light modulators allow us to define and control the spatial mode measurement state. We observe strong quantum correlations, establishing that angular position and momentum distributions between the photons are related as conjugate Fourier pairs.

Determining the dimensionality of bipartite orbital-angular-momentum entanglement using multi-sector phase masks

Giovannini, D., Miatto, F. M., Jacquiline Romero +3 more

The Shannon dimensionality of orbital-angular-momentum (OAM) entanglement produced in spontaneous parametric down-conversion can be probed by using multi-sector phase analysers [1]. We demonstrate a spatial light modulator-based implementation of these analysers, and use it to measure a Schmidt number of about 50.

Orbital angular momentum and quantum entanglement

J. P. Woerdman

In this paper, we focus on the use of orbital angular momentum (OAM) states of light in quantum information science. The OAM degree of freedom is a spatial degree of freedom and is as such intrinsically high dimensional. This offers the possibility of high-dimensional entanglement of two photons, in contrast to the more usual situation where one employs the polarization degree of freedom, which is 2D.
