Universal Parent Hamiltonians for Adiabatic Warm Starts
Feng Qian, Peter J. Love
Computing the ground state properties of quantum systems is an important potential application of quantum computing. The success probability of quantum phase estimation approaches…
Correlation is magic in electronic structure Hamiltonians
Basie Seibert, Sam Alterman, Qingfeng Wang +3
The gate and qubit requirements of quantum computations of electronic structure have been extensively studied. However, the quantum resources present in electronic ground states, a…
Iterative Decoding of Stabilizer Codes under Radiation-Induced Correlated Noise
Anuj K. Nayak, Paul G. Baity, Peter J. Love +4
Fault-tolerant quantum computation demands extremely low logical error rates, yet superconducting qubit arrays are subject to radiation-induced correlated noise arising from cosmic…
Ladder Operator Block-Encoding
William A. Simon, Carter M. Gustin, Kamil Serafin +3
We describe and analyze LOBE (Ladder Operator Block-Encoding), a framework for block-encoding ladder operators that act upon fermionic and bosonic modes. In this framework, we achi…
Extending Quantum Computing through Subspace, Embedding and Classical Molecular Dynamics Techniques
Thomas M. Bickley, Angus Mingare, Tim Weaving +10
The advent of hybrid computing platforms consisting of quantum processing units integrated with conventional high-performance computing brings new opportunities for algorithm desig…
Noncontextual Pauli Hamiltonians
Alexis Ralli, Tim Weaving, Peter J. Love
Contextuality is a key feature of quantum mechanics, and identification of noncontextual subtheories of quantum mechanics is of both fundamental and practical importance. Recently,…
