Space-time wave packets (STWPs) constitute a broad class of pulsed optical fields that are
rigidly transported in linear media without diffraction or dispersion, and are therefore …

Introducing correlations between the spatial and temporal degrees of freedom of a pulsed
optical beam (or wave packet) can profoundly alter its propagation in free space. Indeed …

Diffraction places a fundamental limitation on the distance an optical beam propagates
before its size increases and spatial details blur. We show here that imposing a judicious …

The concept of entanglement is so synonymous with quantum mechanics that the prefix
“quantum” is often deemed unnecessary; there is after all only quantum entanglement. But …

We represent a two-qubit density matrix in the basis of Pauli matrix tensor products, with the
coefficients constituting a Bloch matrix, analogous to the single qubit Bloch vector. We find …

Optical phenomena always display some degree of partial coherence between their
respective degrees of freedom. Partial coherence is of particular interest in multimodal …

The information-carrying capacity of a single photon can be vastly expanded by exploiting its
multiple degrees of freedom: spatial, temporal, and polarization. Although multiple qubits …

This work introduces the concept and experimentation of reversible optical coherence
conversion, and outlines optical coherency matrix tomography as a method for measuring …

Coherence has been used as a resource for optical communications since its earliest days.
It is widely used for the multiplexing of data, but not for the encoding of data. Here we …

Space-time (ST) wave packets are pulsed beams in which the spatial frequencies and
wavelengths are tightly correlated. Proper design of the functional form of these correlations …
