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…

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…
