Connects photonic experiments and quantum algorithms with industrial system design, from a variational molecular-energy demonstration to scientific leadership of PsiQuantum’s photonic computing program.
arXiv / Nature CommunicationsPsiQuantumPsiQuantumShadbolt’s work spans two scales of photonic quantum computing. As a researcher, he co-authored a small quantum–classical experiment for estimating molecular energy. As a PsiQuantum co-founder and scientific leader, he works on the system-level challenge of building a useful photonic computer. That combination makes his contribution distinctive: algorithm experiments test how quantum hardware might be used, while architecture and manufacturing work address how such hardware might grow. The experimental result and the company’s larger ambitions remain separate claims.

Work, in context- 2014
A variational molecular-energy experiment
Shadbolt co-authored a photonic demonstration that combined quantum measurements with classical optimization to estimate the ground-state energy of the helium hydride ion. It supplied an experimental example of the variational quantum eigensolver approach.
Co-author of the Peruzzo et al. hybrid photonic experiment.
