Rydberg atoms, which possess large-dipole moments and the resulting strong dipole- dipole interactions, have been intensively investigated owing to its potential applications in diverse fields ranging from quantum nonlinear optics to quantum information and computation. Exclusive examples includes photon blockade, attractive photons and single-photon transistors, to mention a few.
We devise an all-optical scheme for the generation of entangled multimode photonic states encoded in temporal modes of light. The scheme employs a nonlinear down-conversion process in an optical loop to generate one- and higher-dimensional tensor network states of light. We illustrate the principle with the generation of two different classes of entangled tensor network states and report on a variational algorithm to simulate the ground-state physics of many-body systems.
The Quantum Innovators in science and engineering workshop brings together the most promising young researchers in quantum physics and engineering. Guests are invited for a four-day conference aimed at exploring the frontier of our field.
In recent years, the magnetic random-access memory (MRAM) have been attracting attention as a next generation memory device due to their fast switching speed and non-volatility characteristics. The biggest challenge for the switching device using a magnetic material is an easy magnetization reversal.

Sandia National Laboratories is a multidisciplinary National Laboratory in the United States dedicated to developing advanced technologies. Here, I will explain the ongoing work in quantum information science using trapped ions. In particular, I will describe requirements of surface ion traps fabricated at Sandia’s MESA facility. Additionally, I will discuss results obtained using these traps relevant to building a quantum information platform, including ion shuttling, electric field control, and high-fidelity quantum operations.

Topological insulators are electronic systems with an insulating bulk and topologically protected boundary states. Conventional 2D topological insulators induce 1D edge states. Recent studies indicate that lower-dimensional topological states are also possible in electronic systems, which, however, has been confirmed only in Bismuth in experiments [1].
Stephen Hawking passed away leaving behind a transformed view of the cosmos. He proved that time had a beginning if Einstein's general relativity is correct, that black ain't so black after all and he proposed that the Universe can be described by a quantum mechanical wave function with no edge or boundaries. From 1984 to 1988 I was one of Stephen's graduate students and worked on quantum cosmology and the arrow of time which earned me a quote in the book: "A Brief History of Time".
