Experimental Demonstration of the PBR Test on a Superconducting Processor
Songqinghao Yang, Haomu Yuan, Crispin H. W. Barnes
We present an experimental implementation of the Pusey-Barrett-Rudolph (PBR) no-go theorem on IBM's 156-qubit Heron2 Marrakesh superconducting quantum processor. By preparing qubit…

Iterative quantum optimisation with a warm-started quantum state
Haomu Yuan, Songqinghao Yang, Crispin H. W. Barnes
We provide a method to prepare a warm-started quantum state from measurements with an iterative framework to enhance the quantum approximate optimisation algorithm (QAOA). The nume…
