Graph Theoretic Approach to Quantum Nonstabilizerness
Yingjian Liu, Albert Gasull, Mengyao Hu +3
Detecting nonstabilizerness requires full tomography and an optimization over exponentially many stabilizer states. A limited Pauli measurement set promises resource-efficient magi…
Average-computation benchmarking for local expectation values in digital quantum devices
Flavio Baccari, Pavel Kos, Georgios Styliaris
As quantum devices progress towards a quantum advantage regime, they become harder to benchmark. A particularly relevant challenge is to assess the quality of the whole computation…
Efficient Characterization of Coherent and Correlated Low-Degree Noise in Layers of Gates
Marianna Crupi, J. Ignacio Cirac, Flavio Baccari
We present a quantum process-tomography protocol based on a low-degree ansatz for the quantum channel, i.e. when it can be expressed as a fixed-degree polynomial in terms of Pauli…
A Hierarchy of Spectral Gap Certificates for Frustration-Free Spin Systems
Kshiti Sneh Rai, Ilya Kull, Patrick Emonts +3
Estimating spectral gaps of quantum many-body Hamiltonians is a highly challenging computational task, even under assumptions of locality and translation-invariance. Yet, the quest…
Testing noncontextuality inequalities that are building blocks of quantum correlations
Mauricio Arias, Gustavo Cañas, Esteban S. Gómez +6
Measurement scenarios containing events with relations of exclusivity represented by pentagons, heptagons, nonagons, etc., or their complements are the only ones in which quantum p…
