Categorical Quantum Volume Operator
Alexander Hahn, Sebastian Murk, Sukhbinder Singh +1
We present a generalization of the quantum volume operator quantifying the volume in curved three-dimensional discrete geometries. In its standard form, the quantum volume operator…
Capturing long-range memory structures with tree-geometry process tensors
Neil Dowling, Kavan Modi, Roberto N. Muñoz +2
We introduce a class of quantum non-Markovian processes -- dubbed process trees -- that exhibit polynomially decaying temporal correlations and memory distributed across time scale…
Boundary theories of critical matchgate tensor networks
Alexander Jahn, Marek Gluza, Charlotte Verhoeven +2
Key aspects of the AdS/CFT correspondence can be captured in terms of tensor network models on hyperbolic lattices. For tensors fulfilling the matchgate constraint, these have prev…
On the efficacy of virtual seminars
Hugo Camargo, Michal P. Heller, Ro Jefferson +4
During the SARS-CoV-2 pandemic, theoretical high-energy physics, and likely also the majority of other disciplines, are seeing a surge of virtual seminars as a primary means for sc…
Connector tensor networks: a renormalization-type approach to quantum certification
Miguel Navascues, Sukhbinder Singh, Antonio Acin
As quantum technologies develop, we acquire control of an ever-growing number of quantum systems. Unfortunately, current tools to detect relevant quantum properties of quantum stat…
MERA as a holographic strange correlator
Nathan A. McMahon, Sukhbinder Singh, Gavin K. Brennen
The multi-scale entanglement renormalization ansatz (MERA) is a tensor network that can efficiently parameterize critical ground states on a 1D lattice, and also suggestively imple…
