Characterising extremal decoherence by quantum measurement incompatibility
Daniel McNulty, William Townsend, Jukka Kiukas
Decoherence, when viewed in the Heisenberg picture, can turn incompatible measurements into jointly measurable ones. This provides an observable-level description of emergent class…
A Graph-Theoretic Approach to Quantum Measurement Incompatibility
Daniel McNulty
Measurement incompatibility--the impossibility of jointly measuring certain quantum observables--is a fundamental resource for quantum information processing. We develop a graph-th…
Comment on 'Product states and Schmidt rank of mutually unbiased bases in dimension six'
Daniel McNulty, Stefan Weigert
A lemma by Chen et al. [J. Phys. A: Math. Theor. 50, 475304 (2017)] provides a necessary condition on the structure of any complex Hadamard matrix in a set of four mutually unbiase…
Mutually Unbiased Bases in Composite Dimensions -- A Review
Daniel McNulty, Stefan Weigert
Maximal sets of mutually unbiased bases are useful throughout quantum physics, both in a foundational context and for applications. To date, it remains unknown if complete sets of…
Estimating Quantum Hamiltonians via Joint Measurements of Noisy Non-Commuting Observables
Daniel McNulty, Filip B. Maciejewski, Michał Oszmaniec
Estimation of expectation values of incompatible observables is an essential practical task in quantum computing, especially for approximating energies of chemical and other many-b…
Detecting Entanglement can be More Effective with Inequivalent Mutually Unbiased Bases
B. C. Hiesmayr, D. McNulty, S. Baek +3
Mutually unbiased bases (MUBs) provide a standard tool in the verification of quantum states, especially when harnessing a complete set for optimal quantum state tomography. In thi…
