The Quantum Composition Paradox
Jacob Biamonte
Quantum theory does not generally permit the probability laws obtained from individual unitary steps by the Born rule to be sewn into a consistent genealogy; we classify the except…
Quantum State Certification via Effective Parent Hamiltonians from Local Measurement Data
Guy-Philippe Nadon, Guanyi Heng, Pacôme Gasnier +8
The preparation and certification of quantum states is a fundamental challenge across quantum information technology. We introduce a tomography-free state certification method that…
Barren Plateaus in Variational Quantum Computing
Martin Larocca, Supanut Thanasilp, Samson Wang +7
Variational quantum computing offers a flexible computational paradigm with applications in diverse areas. However, a key obstacle to realizing their potential is the Barren Platea…
Improving Quantum Approximate Optimization by Noise-Directed Adaptive Remapping
Filip B. Maciejewski, Jacob Biamonte, Stuart Hadfield +1
We present Noise-Directed Adaptive Remapping (NDAR), a heuristic algorithm for approximately solving binary optimization problems by leveraging certain types of noise. We consider…
On Commutative Penalty Functions in Parent-Hamiltonian Constructions
Jacob Biamonte
There are several known techniques to construct a Hamiltonian with an expected value that is minimized uniquely by a given quantum state. Common approaches include the parent Hamil…
Progress towards analytically optimal angles in quantum approximate optimisation
D. Rabinovich, R. Sengupta, E. Campos +2
The Quantum Approximate Optimisation Algorithm is a layer, time-variable split operator method executed on a quantum processor and driven to convergence by classical outer loop…
