Improved quantum sampling methods for molecular simulations
Connor van Rossum, Jeffery Cohn, Sally Shrapnel +1
Quantum-selected configuration interaction (QSCI) methods use a quantum computer to identify dominant electronic configurations in the molecular ground state, while a classical com…

Quantum advantage without exponential concentration: Trainable kernels for symmetry-structured data
Laura J. Henderson, Kerstin Beer, Salini Karuvade +3
Quantum kernel methods promise enhanced expressivity for learning structured data, but their usefulness has been limited by kernel concentration and barren plateaus. Both effects a…

Characterizing noisy quantum computation with imperfectly addressed errors
Riddhi S. Gupta, Salini Karuvade, Kerstin Beer +2
Quantum protocols on hardware are subject to noise that prohibits performance. Protocols for addressing errors, such as error correction or error mitigation, may fail to combat err…
