Topology plays a central role in the modern condensed matter, quantum information and high-energy physics. Certain Geometric manipulation of the manifold which supports a particular topological, known as the modular transformations, can be used as fault-tolerant logical operations in the context of both topological phases and topological quantum error correction codes. We realized that such transformations can be implemented in a single shot (i.e., with constant circuit depth), using local transversal SWAP operations between patches in a folded system with twist defects (wormholes in the synthetic dimension).

"Hardware-efficient quantum algorithm for fermionic simulation with cavity-QED systems" appeared on arXivAugust 06, 2017
A promising near-term application of a quantum computer consisting of O(100) qubits is quantum simulation of fermionic systems, which exceeds the computational power of the world’s largest classical supercomputer due to the exponential growth of the Hilbert-space size. The target systems range f
Arxiv preprint on the measurement protocol of the entanglement spectrum of a quantum many-body systemJune 01, 2016
Entanglement spectrum, the full spectrum of the reduced density matrix of a subsystem, plays a major role in characterising many-body quantum systems. In recent years, it has been widely studied in the fields of condensed matter physics, quantum information, high energy and black-hole physics.

A hallmark feature of topological physics is the presence of one-way propagating chiral modes at the system boundary. The chirality of these edge modes is a consequence of the topological character of the bulk.
