Hierarchical Fusion Method for Scalable Quantum Eigenstate Preparation

Matthew Patkowski, Onat Ayyildiz, Matjaž Kebrič +2

Robust and efficient eigenstate preparation is a central challenge in quantum simulation. The Rodeo Algorithm (RA) offers exponential convergence to a target eigenstate but suffers…

Design and Dynamics of Two-Qubit Gates with Motional States of Electrons on Helium

Oskar Leinonen, Jonas B. Flaten, Stian D. Bilek +6

Systems of individual electrons electrostatically trapped on condensed noble gas surfaces have recently attracted considerable interest as potential platforms for quantum computing…

Spectroscopy of Quantum Phase Slips: Visualizing Complex Real-Time Instantons

Foster Thompson, Daniel K. J. Boneß, Mark Dykman +1

Parametrically driven oscillators can emerge as a basis for the next generation of qubits. Classically, these systems exhibit two stable oscillatory states with opposite phases. Up…

Quantum State Preparation with Resolution Refinement

Scott Bogner, Heiko Hergert, Morten Hjorth-Jensen +3

We introduce a method called resolution refinement that allows one to bootstrap eigenstate preparation on a quantum computer. We first prepare an eigenstate of a low-resolution Ham…

A note on the quantum Wielandt inequality

Owen Ekblad

In this note, we prove that the index of primitivity of any primitive unital Schwarz map is at most , where is the dimension of the underlying matrix algebra. This in…

Controlled Gate Networks: Theory and Application to Eigenvalue Estimation

Max Bee-Lindgren, Zhengrong Qian, Matthew DeCross +5

We introduce a new scheme for quantum circuit design called controlled gate networks. Rather than trying to reduce the complexity of individual unitary operations, the new strategy…
