A converse to Lieb-Robinson bounds in one dimension using index theory
Daniel Ranard, Michael Walter, Freek Witteveen
Unitary dynamics with a strict causal cone (or "light cone") have been studied extensively, under the name of quantum cellular automata (QCAs). In particular, QCAs in one dimension…
Quantum algorithms for matrix scaling and matrix balancing
Joran van Apeldoorn, Sander Gribling, Yinan Li +3
Matrix scaling and matrix balancing are two basic linear-algebraic problems with a wide variety of applications, such as approximating the permanent, and pre-conditioning linear sy…
Matchgate benchmarking: Scalable benchmarking of a continuous family of many-qubit gates
Jonas Helsen, Sepehr Nezami, Matthew Reagor +1
We propose a method to reliably and efficiently extract the fidelity of many-qubit quantum circuits composed of continuously parametrized two-qubit gates called matchgates. This me…
Bosonic entanglement renormalization circuits from wavelet theory
Freek Witteveen, Michael Walter
Entanglement renormalization is a unitary real-space renormalization scheme. The corresponding quantum circuits or tensor networks are known as MERA, and they are particularly well…
Hypergraph min-cuts from quantum entropies
Michael Walter, Freek Witteveen
The min-cut function of weighted hypergraphs and the von Neumann entropy of pure quantum states are both symmetric submodular functions. In this note, we explain this coincidence b…
