Efficient classical simulation of large-scale unitary cluster Jastrow circuits
Hrishikesh Belagali, Thomas Van Camp, R. Pradeep +3
Recent experiments on quantum computers have challenged the limits of classical computation in chemistry, simulating ground states of strongly correlated molecules. Many of these e…
Universality and Dynamical Inequivalence in Isospectral Non-Hermitian Anderson Transitions
Aziz Hasan, Anant Vijay Varma, Namit Anand +1
The Hatano Nelson paradigm establishes that extensive bulk nonreciprocity can destabilize Anderson localization via an imaginary gauge flux. Here, we demonstrate that extensive non…
Violations of the Leggett-Garg inequality in Hybrid Liouvillian Dynamics: The Nonlinear Role of Detector Efficiency
Sourav Paul, Parveen Kumar, Sourin Das
Violations of the Leggett-Garg inequality (LGI) up to its algebraic bound under non-Hermitian dynamics are well established theoretically. Here, we demonstrate that such extreme vi…
Chaos-Mediated Quantum State Discrimination Near Unit Fidelity
Sourav Paul, Anant Vijay Varma, Yogesh N. Joglekar +1
We investigate a ''quantum microscope'' for qubits based on nonlinear discrete-time chaotic dynamics, which exponentially amplifies the initially small fidelity of a pair of states…
