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…
Maximum-Entropy Extension of Quantum Correlation Functions from Short Real-Time Dynamics
Filippo Maria Gambetta, Sabrina Yue Wang, Raul A. Santos
Correlation functions are central to understanding the behavior of quantum systems, with their spectra giving direct access to quasiparticle and collective excitations. However, th…
Quantum algorithm for dephasing of coupled systems: decoupling and IQP duality
Sabrina Yue Wang, Raul A. Santos
Noise and decoherence are ubiquitous in the dynamics of quantum systems coupled to an external environment. In the regime where environmental correlations decay rapidly, the evolut…
Programmable digital quantum simulation of 2D Fermi-Hubbard dynamics using 72 superconducting qubits
Faisal Alam, Jan Lukas Bosse, Ieva Čepaitė +41
Simulating the time-dynamics of quantum many-body systems was the original use of quantum computers proposed by Feynman, motivated by the critical role of quantum interactions betw…
Fermionic dynamics on a trapped-ion quantum computer beyond exact classical simulation
Faisal Alam, Jan Lukas Bosse, Ieva Čepaitė +37
Simulation of the time-dynamics of fermionic many-body systems has long been predicted to be one of the key applications of quantum computers. Such simulations -- for which classic…
Extracting the spin excitation spectrum of a fermionic system using a quantum processor
Lucia Vilchez-Estevez, Raul A. Santos, Sabrina Yue Wang +1
Understanding low-energy excitations in fermionic systems is crucial for their characterization. They determine the response of the system to external weak perturbations, its dynam…
