Overshifted Parameter-Shift Rules: Optimizing Complex Quantum Systems with Few Measurements
Leonardo Banchi, Dominic Branford, Chetan Waghela
Gradient-based optimization is a key ingredient of variational quantum algorithms, with applications ranging from quantum machine learning to quantum chemistry and simulation. The…
Simulation of exceptional-point systems on quantum computers for quantum sensing
Chetan Waghela, Shubhrangshu Dasgupta
There has been debate around applicability of exceptional points (EP) for quantum sensing. To resolve this, we first explore how to experimentally implement the nonhermitian non-di…
A unified picture of Balance puzzles and Group testing: Some lessons from quantum mechanics for the pandemic
Chetan Waghela
Balance (Counterfeit coin) puzzles have been part of recreational mathematics for a few decades. A particular type of Counterfeit coin puzzle is known in the literature as the "Bea…
Optomechanical non-reciprocity and its equivalence to antiresonance: Control of isolation frequency using mechanical drive
Chetan Waghela, Shubhrangshu Dasgupta
We demonstrate that optomechanical non-reciprocity is equivalent to the anti-resonance, often discussed in the context of coupled driven harmonic oscillators. We show that that sui…
A detailed analysis of mathematics of entanglement in Non-Hermitian systems in real eigenvalue regime
Chetan Waghela
Hamiltonian Mechanics works for conserved systems and Quantum Mechanics is given in Hamiltonian language. It is considered that complexifying the quantum Hamiltonian, a balanced lo…
