Quantum Circuit Optimization using Differentiable Programming of Tensor Network States

David Rogerson, Ananda Roy

Efficient quantum circuit optimization schemes are central to quantum simulation of strongly interacting quantum many body systems. Here, we present an optimization algorithm which…

Entanglement entropy and negativity in the Ising model with defects

David Rogerson, Frank Pollmann, Ananda Roy

Defects in two-dimensional conformal field theories (CFTs) contain signatures of their characteristics. In this work, we compute the entanglement entropy (EE) and the entanglement…

Spin-wave propagation in metallic CoFe films determined by microfocused frequency-resolved magneto-optic Kerr effect

Lukas Liensberger, Luis Flacke, David Rogerson +3

We investigated the magnetization dynamics of a patterned CoFe-based heterostructure with a novel optical measurement technique that we call microfocused frequency-re…

Universal Euler-Cartan Circuits for Quantum Field Theories

Ananda Roy, Robert M. Konik, David Rogerson

Quantum computers can efficiently solve problems which are widely believed to lie beyond the reach of classical computers. In the near-term, hybrid quantum-classical algorithms, wh…

Simulating Lattice Gauge Theories with Virtual Rishons

David Rogerson, João Barata, Robert M. Konik +2

Classical tensor network and hybrid quantum-classical algorithms are promising candidates for the investigation of real-time properties of lattice gauge theories. We develop here a…
