The Geometry of Quantum Computing
E. Ercolessi, R. Fioresi, T. Weber
In this expository paper we present a brief introduction to the geometrical modeling of some quantum computing problems. After a brief introduction to establish the terminology, we…
Quantum Fisher Information and multipartite entanglement in spin-1 chains
Federico Dell'Anna, Sunny Pradhan, Cristian Degli Esposti Boschi +1
In this paper, we study the ground state Quantum Fisher Information (QFI) in one-dimensional spin-1 models, as witness to Multipartite Entanglement. The models addressed are the Bi…
Hamiltonians and gauge-invariant Hilbert space for lattice Yang-Mills-like theories with finite gauge group
A. Mariani, S. Pradhan, E. Ercolessi
Motivated by quantum simulation, we consider lattice Hamiltonians for Yang-Mills gauge theories with finite gauge group, for example a finite subgroup of a compact Lie group. We sh…
Entanglement Classification via Witness Operators generated by Support Vector Machine
Claudio Sanavio, Edoardo Tignone, Elisa Ercolessi
Although entanglement is a basic resource for reaching quantum advantange in many computation and information protocols, we lack a universal recipe for detecting it, with analytica…
