QAOA-MaxCut has barren plateaus for almost all graphs
Rui Mao, Pei Yuan, Jonathan Allcock +1
The QAOA has been the subject of intense study over recent years, yet the corresponding Dynamical Lie Algebra (DLA)--a key indicator of the expressivity and trainability of VQAs--r…

On generating direct powers of dynamical Lie algebras
Jonathan Allcock, Miklos Santha, Pei Yuan +1
The expressibility and trainability of parameterized quantum circuits has been shown to be intimately related to their associated dynamical Lie algebras (DLAs). From a quantum algo…

Depth-Efficient Quantum Circuit Synthesis for Deterministic Dicke State Preparation
Pei Yuan, Shengyu Zhang
The -qubit -weight Dicke states , defined as the uniform superposition of all computational basis states with exactly qubits in state , form a b…
