Future graduate students

Two-dimensional nanomaterials could cause structural disruption and cytotoxic effects to cells, which greatly challenges their promising biomedical applications including biosensing, bioimaging, and drug delivery. Here, interactions between lipid liposomes and hydrophobic nanosheets is studied utilizing coarse-grained (CG) molecular dynamics (MD) simulations. The simulations reveal a variety of interaction morphologies that depend on the size and the orientation of nanosheets.

Join us at the Institute for Quantum Computing for a two-week introduction to the theoretical and experimental study of quantum information processing.

During the Undergraduate School on Experimental Quantum Information Processing (USEQIP) will be exposed to lectures and experiments on the following topics and more.

Neutron whispering gallery

Dr Valery Nesvizhevsky, European Centre for Neutron Research, Institut Laue-Langevin

The "whispering gallery" effect has been known since ancient times for sound waves in air, later in water and more recently for a broad range of electromagnetic waves: radio, optics, Roentgen and so on. It consists of wave localization near a curved reflecting surface and is expected for waves of various natures, for instance, for atoms and neutrons. For matter waves, it would include a new feature: a massive particle would be settled in quantum states, with parameters depending on its mass. In 2010, we observed the quantum whispering gallery effect for cold neutrons and since then continue increasing the precision in these experiments.

An outstanding open question in quantum information theory concerns the computational complexity of nonlocal games. in a nonlocal game, a classical verifier interacts with multiple players that cannot communicate, but are allowed to share entanglement. In a recent breakthrough result, Slofstra showed that the following problem is undecidable: given a nonlocal game, is there a quantum strategy for the players to win with probability 1?

QUANTUM + Pop Culture

“Quantum physics” has taken its position with “rocket science” in pop culture as a shorthand for frighteningly complicated science. Quantum physics has also taken on a sort of magical connotation in fiction, with features like entanglement, superposition, and tunneling spurring imagination. But where does the science draw the line? How much is joyful speculation, and how much is disregard for reality? And if it’s always seen as either magical or scary, how does that affect the perception of quantum science?

The quantum query complexity of a function f measures how many bits of the input a quantum computer must look at in order to compute f. 

Topological cavity states in two-dimensional photonic/phononic chips

Jian-Hua Jiang, School of Physical Science and Technology, Soochow University

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].

The study of high-efficiency magnetization reversal using spin-orbit coupling

Dongseuk Kim, Quantum Technology Institute, KRISS, South Korea

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.

Ish Dhand, University of Ulm

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.
