Majorana loop stabilizer codes for error correction of fermionic quantum simulations
Zhang Jiang, Jarrod McClean, Ryan Babbush +1
Fermion-to-qubit mappings that preserve geometric locality are especially useful for simulating lattice fermion models (e.g., the Hubbard model) on a quantum computer. They avoid t…
Postponing the orthogonality catastrophe: efficient state preparation for electronic structure simulations on quantum devices
Norm M. Tubman, Carlos Mejuto-Zaera, Jeffrey M. Epstein +8
Despite significant work on resource estimation for quantum simulation of electronic systems, the challenge of preparing states with sufficient ground state support has so far been…
Fluctuations of Energy-Relaxation Times in Superconducting Qubits
P. V. Klimov, J. Kelly, Z. Chen +30
Superconducting qubits are an attractive platform for quantum computing since they have demonstrated high-fidelity quantum gates and extensibility to modest system sizes. Nonethele…
Quantum Simulation of Chemistry with Sublinear Scaling in Basis Size
Ryan Babbush, Dominic W. Berry, Jarrod R. McClean +1
We present a quantum algorithm for simulating quantum chemistry with gate complexity where is the number of electrons and is the number of plan…
Quantum Simulation of the Sachdev-Ye-Kitaev Model by Asymmetric Qubitization
Ryan Babbush, Dominic Berry, Hartmut Neven
We show that one can quantum simulate the dynamics of a Sachdev-Ye-Kitaev model with Majorana modes for time to precision with gate complexity $O(N^{7/2} t + N^{5/2} t…
Encoding Electronic Spectra in Quantum Circuits with Linear T Complexity
Ryan Babbush, Craig Gidney, Dominic W. Berry +5
We construct quantum circuits which exactly encode the spectra of correlated electron models up to errors from rotation synthesis. By invoking these circuits as oracles within the…
