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…
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…
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…
Reply to the Comment on `The operational foundations of PT-symmetric and quasi-Hermitian quantum theory'
Abhijeet Alase, Salini Karuvade, Carlo Maria Scandolo
This document is our reply to the Comment (Miloslav Znojil 2023 J. Phys. A: Math. Theor. 56, 038001) on our recent work titled `The operational foundations of PT-symmetric and quas…
The operational foundations of PT-symmetric and quasi-Hermitian quantum theory
Abhijeet Alase, Salini Karuvade, Carlo Maria Scandolo
PT-symmetric quantum theory was originally proposed with the aim of extending standard quantum theory by relaxing the Hermiticity constraint on Hamiltonians. However, no such exten…
Security for Quantum Networks
Salini Karuvade, Barry C. Sanders
Reliable and efficient functioning of a quantum network depends on identifying and mitigating security risks originating from within and outside the network. We aim to construct a…
Observing a Changing Hilbert-Space Inner Product
Salini Karuvade, Abhijeet Alase, Barry C. Sanders
In quantum mechanics, physical states are represented by rays in Hilbert space , which is a vector space imbued by an inner product , whose physica…
Uniquely determined pure quantum states need not be unique ground states of quasi-local Hamiltonians
Salini Karuvade, Peter D. Johnson, Francesco Ticozzi +1
We consider the problem of characterizing states of a multipartite quantum system from restricted, quasi-local information, with emphasis on uniquely determined pure states. By lev…
Generic pure quantum states as steady states of quasi-local dissipative dynamics
Salini Karuvade, Peter D. Johnson, Francesco Ticozzi +1
We investigate whether a generic multipartite pure state can be the unique asymptotic steady state of locality-constrained purely dissipative Markovian dynamics. In the simplest tr…
