Grant Writing 1/2 (Education Grants)

How to write successful grant proposals, pushing your writing skills to the next level. Erin will provide a general overview of grant writing and focus on proposals for education and outreach, a key mandate of the NSF grant for the Quantum Leap Challenge Institute for Robust Quantum Simulation.

Please prepare your questions in advance and send them to rqs-seed@umiacs.umd.edu.

Exploring one-dimensional Z2 lattice gauge theories with dynamical matter

Although lattice gauge theories are primarily considered in particle physics, they are also a valuable platform to study strongly correlated quantum systems in condensed-matter physics. Particularly interesting is the study of confinement, which can arise when dynamical charges are coupled to gauge fields. In this talk, I will present our recent work on a one-dimensional Z2 lattice gauge theory (LGT), where dynamical matter is coupled to Z2 gauge field [1].

Position Verification with Classical Communication

Position verification is the task of verifying the geographical position of a party using computational tasks and physical bounds on the speed of communication. It has been shown that position verification is impossible in the classical setting, but using non-clonability it is shown that one can construct quantum position verification (QPV) schemes. These schemes are secure against any individual attacker, but can be broken by colluding attackers that share a large amount of entanglement.

Quantum recurrent neural networks

I will talk about quantum recurrent neural networks based on quantum dissipative neural networks (DQNNs), which use quantum neural networks to describe general causal quantum automata. I will first introduce feed-forward DQNNs and then go to the recurrent case. After discussing the architecture and universality, I will discuss training algorithms and numerical results showing good generalisation behaviour.

Phase diagram of the XXZ spin-1/2 model on the pyrochlore lattice and its relation to the Programmable Rydberg Atoms Simulator

The spin-1/2 nearest-neighbor XXZ model on the pyrochlore lattice is an iconic frustrated three-dimensional spin system with a rich phase diagram on the $\lambda$ axis, where $\lambda$ is the XXZ interaction anisotropy.

New species of butterflies reported in topological crystalline states

The study of topological phases of matter and the invariants that define them has become a central pursuit of condensed matter physics. In particular, crystalline systems are known to host a large set of topological invariants, but the physical response properties associated to them are still not fully understood.

Entanglement, dynamics and computation in many-body systems with power-law interactions

Quantum many-body systems with long-range interactions—such as those that decay as a power-law in the distance between particles—are promising candidates for quantum information processors. Due to their high degree of connectivity, they are potentially capable of generating entanglement more quickly than systems limited to local interactions, which may lead to faster computational speeds.
