Formal Verification of Quantum Ancilla Safety
Jiqi Li, Jingyi Mei, Wang Fang +1
Ensuring ancilla safety is a critical correctness requirement for quantum compilation, since ancilla qubits are routinely introduced to implement complex operations with fewer gate…
Provable quantum speedups for computing persistence in topological data analysis
Casper Gyurik, Alexander Schmidhuber, Robbie King +2
Topological data analysis (TDA) aims to extract noise-robust features from a data set by examining the number and persistence of holes in its topology. We provide an efficient quan…
Frustration graph formalism for qudit observables
Owidiusz Makuta, BÅażej Kuzaka, Remigiusz Augusiak
The incompatibility of measurements is the key feature of quantum theory that distinguishes it from the classical description of nature. Here, we consider groups of d-outcome quant…
Nonlocality, Integrability and Quantum Chaos in the Spectrum of Bell Operators
Albert Aloy, Guillem Müller-Rigat, Maciej Lewenstein +2
We introduce a permutationally invariant multipartite Bell inequality for many-body three-level systems and use it to investigate a connection between Bell nonlocality and (lack of…
Noise tolerance via reinforcement in the quantum search problem
Marjan Homayouni-Sangari, Abolfazl Ramezanpour
The Grover lower bound for the unstructured search problem can be surpassed when some information about the data structure is available. Here, we numerically observe that reinforce…
Entanglement witnesses for stabilizer states and subspaces beyond qubits
Jakub Szczepaniak, Owidiusz Makuta, Remigiusz Augusiak
Genuine multipartite entanglement is arguably the most valuable form of entanglement in the multipartite case, with applications, for instance, in quantum metrology. In order to de…
