Instability-Enhanced Quantum Sensing with Tunable Multibody Interactions
Bidhi Vijaywargia, Jorge Chávez-Carlos, Francisco Pérez-Bernal +1
Dynamical instabilities can amplify small perturbations into measurable signals, offering a route to quantum-enhanced sensing. This mechanism was experimentally demonstrated in a c…
Qumode-Based Variational Quantum Eigensolver for Molecular Excited States
Rishab Dutta, Cameron Cianci, Alexander V. Soudackov +5
We introduce the Qumode Subspace Variational Quantum Eigensolver (QSS-VQE), a hybrid quantum-classical algorithm for computing molecular excited states using the Fock basis of boso…
Phase transitions, symmetries, and tunneling in Kerr parametric oscillators
Miguel A. Prado Reynoso, Edson M. Signor, Jamil Khalouf-Rivera +3
Quantum Kerr parametric oscillators (KPOs) are systems out of equilibrium with a wide range of applications in quantum computing, quantum sensing, and fundamental research. They ha…
A Roadmap for Simulating Chemical Dynamics on a Parametrically Driven Bosonic Quantum Device
Delmar G. A. Cabral, Pouya Khazaei, Brandon C. Allen +8
Chemical reactions are commonly described by the reactive flux transferring population from reactants to products across a double-well free energy barrier. Dynamics often involves…
