Blind-spots of Randomized Benchmarking Under Temporal Correlations
Varun Srivastava, Abhinash Kumar Roy, Soumik Mahanti +3
Randomized benchmarking (RB) is a widely adopted protocol for estimating the average gate fidelity in quantum hardware. However, its standard formulation relies on the assumption o…
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…
Resolvent-based quantum phase estimation: Towards estimation of parametrized eigenvalues
Abhijeet Alase, Salini Karuvade
Quantum algorithms for estimating the eigenvalues of matrices, including the phase estimation algorithm, serve as core subroutines in a wide range of quantum algorithms, including…
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…
