Observable Estimation in the Absence of Classical Verification
Samantha V. Barron, Bradley Mitchell, Vinay Tripathi +45
The predictive success of quantum mechanics underpins many areas of modern science, even as the exact simulation of large, interacting quantum systems remains beyond the reach of c…
Theory of quantum error mitigation for non-Clifford gates
David Layden, Bradley Mitchell, Karthik Siva
Quantum error mitigation techniques mimic noiseless quantum circuits by running several related noisy circuits and combining their outputs in particular ways. How well such techniq…
Empowering high-dimensional quantum computing by traversing the dual bosonic ladder
Long B. Nguyen, Noah Goss, Karthik Siva +6
High-dimensional quantum information processing has emerged as a promising avenue to transcend hardware limitations and advance the frontiers of quantum technologies. Harnessing th…
Time-Dependent Hamiltonian Reconstruction using Continuous Weak Measurements
Karthik Siva, Gerwin Koolstra, John Steinmetz +9
Reconstructing the Hamiltonian of a quantum system is an essential task for characterizing and certifying quantum processors and simulators. Existing techniques either rely on proj…
Universal tripartite entanglement in one-dimensional many-body systems
Yijian Zou, Karthik Siva, Tomohiro Soejima +2
Motivated by conjectures in holography relating the entanglement of purification and reflected entropy to the entanglement wedge cross-section, we introduce two related non-negativ…
