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…
Engineering nonequilibrium steady states through Floquet Liouvillians
Weijian Chen, Maryam Abbasi, Serra Erdamar +3
We experimentally study the transient dynamics of a dissipative superconducting qubit under periodic drive towards its nonequilibrium steady states. The corresponding stroboscopic…
Programmable high-dimensional Hamiltonian in a photonic waveguide array
Yang Yang, Robert J. Chapman, Ben Haylock +4
Waveguide lattices offer a compact and stable platform for a range of applications, including quantum walks, topological effects, condensed matter system simulation, and classical…
Non-Hermiticity in quantum nonlinear optics through symplectic transformations
Ross Wakefield, Anthony Laing, Yogesh N. Joglekar
Over the past decade classical optical systems with gain or loss, modelled by non-Hermitian parity-time symmetric Hamiltonians, have been deeply investigated. Yet, their applicabil…
PT-symmetry enabled stable modes in multi-core fiber
Tamara Gratcheva, Yogesh N. Joglekar, Jay Gopalakrishnan
Open systems with balanced gain and loss, described by parity-time PT-symmetric Hamiltonians have been deeply explored over the past decade. Most explorations are limited to finite…
