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…
Non-stabilizerness in kinetically-constrained Rydberg atom arrays
Ryan Smith, Zlatko Papić, Andrew Hallam
Non-stabilizer states are a fundamental resource for universal quantum computation. However,despite broad significance in quantum computing, the emergence of "many-body" non-stabil…
Integrability breaking and bound states in Google's decorated XXZ circuits
Ana Hudomal, Ryan Smith, Andrew Hallam +1
Recent quantum simulation by Google [Nature 612, 240 (2022)] has demonstrated the formation of bound states of interacting photons in a quantum-circuit version of the XXZ spin chai…
