Engineering and characterization of nonclassical sources of light (Conference Presentation)

Abstract

A great deal of research in optics concentrates on developing quantum methods ranging from precision measurement to optical telecommunication, and from quantum information processing to fundamental tests of nature. To this aim, engineering and characterization of quantum states of light becomes extremally important. Nonclassical sources are based on various underlying physical phenomena, from parametric downconversion and four-wave mixing to solid state and atomic single emitters to ensembles of atoms or ions. I will discuss recent efforts in engineering and characterization of nonclassical light states applicable to a broad range of sources, predominantly based on tunable narrow-band filtering.

Single-Mode Quantum Non-Gaussian Light from Warm Atoms

Jaromír Mika, Lukáš Lachman, Tomas Lamich +2 more

Quantum non-Gaussianity (QNG) corresponds to an essential resource in many prospective applications of quantum technologies. QNG states of light have been demonstrated in a broad range of experimental platforms with various complementary advantages [1]. However, in order to allow for their direct and efficient utilization for interaction with the target quantum system, their degrees of freedom have to be well-defined and controllable. This imposes a requirement on the generation of QNG light in a single optical mode. While the intrinsic single-photon sources including trapped ions, atoms, or molecules, naturally offer a close-to a single mode emission, their technologically more accessible counterparts including majority of the solid-state emitters and sources based on heralded generation of nonclassical states in various parametric nonlinear processes typically provide a multi-mode output. Although several demonstrations of a single-mode operation of nonclassical light sources based on these platforms have been recently demonstrated, an unambiguous observation of a single-mode QNG light has never been presented.

Nonclassical Light

Christopher C. Gerry, P. L. Knight

This established textbook provides an accessible but comprehensive introduction to the quantum nature of light and its interaction with matter. The field of quantum optics is covered with clarity and depth, from the underlying theoretical framework of field quantization, atom–field interactions, and quantum coherence theory, to important and modern applications at the forefront of current research such as quantum interferometry, squeezed light, quantum entanglement, cavity quantum electrodynamics, laser-cooled trapped ions, and quantum information processing. The text is suitable for advanced undergraduate and graduate students and would be an ideal main text for a course on quantum optics. This long-awaited second edition builds upon the success of the first edition, including many new developments in the field, particularly in the area of quantum state engineering. Additional homework problems have been added, and content from the first edition has been updated and clarified throughout.

Quantum enhanced classical imaging and metrology (Conference Presentation)

B. Stoklasa, Jaroslav Řeháček, Z. Hradil +3 more

The concepts of quantum detection and estimation theory can be of great help in the analysis of faint signals, which must be treated with extreme care due to the fragility and subtlety. But this is surely not the only domain, where the advanced concepts may be applied. Strong optical fields can be analyzed by similar techniques since by virtue of first quantization any optical wave plays role of a quantum state. More precisely, a classical mode of light can be given and alternative interpretation as a quantum state of the spatial degrees of freedom of a photon. Here the formulation of classical optics meets those of quantum information processing. The goal of the research is to optimize classical sensing schemes of strong signals in order to attain the best performance allowed by Nature. As examples of the approach, measurement of two point-like sources separation and full characterization of laser beams by a phase-space tomography will be discussed both theoretically and experimentally.

Nonclassical Light from Large Ensembles of Trapped Ions

Petr Obšil, Lukáš Lachman, T. Pham +7 more

The vast majority of physical objects we are dealing with are almost exclusively made of atoms. Because of their discrete level structure, single atoms have proved to be emitters of light, which is incompatible with the classical description of electromagnetic waves. We demonstrate this incompatibility for atomic fluorescence when scaling up the size of the source ensemble, which consists of trapped atomic ions, by several orders of magnitude. The presented measurements of nonclassical statistics on light unconditionally emitted from ensembles containing up to more than a thousand ions promise further scalability to much larger emitter numbers. The methodology can be applied to a broad range of experimental platforms focusing on the bare nonclassical character of single isolated emitters.

Atom-Mediated Nonlinear Sources of Quantum Light

Aleksa Krstić, Priyanshu Tiwari, Frank Setzpfandt +2 more

Sources of highly nonclassical light are important building blocks of many proposed implementations of optical quantum technologies [1]. The most common realisations of nonclassical light sources are either based on two-level quantum emitters or on nonlinear sources of photon pairs and squeezed light [2] and are generally limited in the properties of the quantum states of light they can efficiently generate: single-photon states for two-level systems and squeezed states (with a Gaussian Wigner function) for nonlinear sources.

The Journey from Manipulating Single Quantum Systems to Quantum Information Processing

P. L. Knight

Quantum Optics for some years has concentrated on the role of discreteness, of the limits of the uncertainty relation in governing fluctuations and the nature of quantum correlations beyond what is allowed classically. Progress in identifying, generating and characterizing nonclassical states at the single quantum system level has been spectacular, for example using single trapped laser cooled ions or cavity QED.
