Topology plays a central role in the modern condensed matter, quantum information and highenergy physics. Certain Geometric manipulation of the manifold which supports a particular topological, known as the modular transformations, can be used as faulttolerant 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).

A promising nearterm 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 Hilbertspace size. The target systems range f

Entanglement spectrum, the full spectrum of the reduced density matrix of a subsystem, plays a major role in characterising manybody quantum systems. In recent years, it has been widely studied in the fields of condensed matter physics, quantum information, high energy and blackhole physics.

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