Efficient estimation of error bounds for quantum multiparametric imaging with constraints
Alexander Mikhalychev, Saif Almazrouei, Svetlana Mikhalycheva +3
Advanced super-resolution imaging techniques require specific approaches for accurate and consistent estimation of the achievable spatial resolution. Fisher information supplied to…
Boosting quantum annealing performance through direct polynomial unconstrained binary optimization
Sebastian Nagies, Kevin T. Geier, Javed Akram +3
Quantum annealing aims at solving optimization problems of practical relevance using quantum-computing hardware. Problems of interest are typically formulated in terms of quadratic…
A nonstabilizerness monotone from stabilizerness asymmetry
Poetri Sonya Tarabunga, Martina Frau, Tobias Haug +2
We introduce a nonstabilizerness monotone which we name basis-minimised stabilizerness asymmetry (BMSA). It is based on the notion of -asymmetry, a measure of how much a certain…
Efficient Eigenstate Preparation in an Integrable Model with Hilbert Space Fragmentation
Roberto Ruiz, Alejandro Sopena, Balázs Pozsgay +1
We consider the preparation of all the eigenstates of spin chains using quantum circuits. It is known that generic eigenstates of free-fermionic spin chains can be prepared with ci…
Threetangle in the XY-model class with a non-integrable field background
Jörg Neveling, Andreas Osterloh
The square root of the threetangle is calculated for the transverse XY-model with an integrability-breaking in-plane field component. To be in a regime of quasi-solvability of the…
Expressibility, entangling power and quantum average causal effect for causally indefinite circuits
Pedro C. Azado, Guilherme I. Correr, Alexandre Drinko +3
Parameterized quantum circuits are the core of new technologies such as variational quantum algorithms and quantum machine learning, which makes studying its properties a valuable…
