Nonlinear quantum evolution of a dissipative superconducting qubit
Orion Lee, Qian Cao, Yogesh N. Joglekar +1
Unitary and dissipative models of quantum dynamics are linear maps on the space of states or density matrices. This linearity encodes the superposition principle, a key feature of…

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…
