Non-adiabatic Optimisation via Localisation-Delocalisation Transitions
Ryan Smith, Sabrina Yue Wang, Filippo Maria Gambetta +1
The promise of efficiently solving classical optimisation problems on quantum computers is tantalizing. As many such problems can be mapped to approximating the ground state of spi…
Simulating Black Hole Thermality and Interior Scrambling on a Superconducting Quantum Processor
Ryan Smith, Ewan Forbes, Iason A. Sofos +4
We implement a chiral spin-chain black hole simulator on IBM superconducting quantum hardware and probe, within a common microscopic framework, both semiclassical horizon physics a…
Robust Quantum Sensing via Prethermal Spin Orbits
Enrico Daniel Richter, Ryan J. Smith, Brayden Glockzin +3
Practical performance of quantum sensors is often curtailed by uncontrolled environmental drift (bias-field instability, temperature fluctuations, mechanical vibration), background…
Spectral signatures of nonstabilizerness and criticality in infinite matrix product states
Andrew Hallam, Ryan Smith, Zlatko Papić
While nonstabilizerness (''magic'') is a key resource for universal quantum computation, its behavior in many-body quantum systems, especially near criticality, remains poorly unde…
