Quantum Decoding Algorithms: Quantum Speedups in Optimization
Jan Ljubas, Tim Byrnes
Attaining a quantum speedup in solving practically useful optimization problems has been one of the holy grails in the field of quantum computing. While prior approaches have demon…
Hybrid Quantum Error Correction and Mitigation by Purification
Jonathan Raghoonanan, Tim Byrnes
Quantum error correction physically removes errors from a quantum state, while quantum error mitigation improves observable estimates by processing noisy measurement data. We intro…
The stabilizer ground state and applications to quantum simulation
Yuping Mao, Chang Chen, Jiaxing Feng +2
The stabilizer ground state is defined is the lowest energy stabilizer state with respect to a given Hamiltonian. In many cases it is highly degenerate and does not give a unique s…
Polynomially restricted operator growth in dynamically integrable models
Igor Ermakov, Tim Byrnes, Oleg Lychkovskiy
We provide a framework to determine the upper bound to the complexity of a computing a given observable with respect to a Hamiltonian. By considering the Heisenberg evolution of th…
