Fast Bosonic Control via Multiphoton Qubit-Oscillator Interactions
Noah Gorgichuk, Mohammad Ayyash, Matteo Mariantoni +1
We present a protocol for preparing oscillator states with -fold rotational symmetry, which include many logical codewords for bosonic quantum error correction codes. The protoc…
Dispersive regime of multiphoton qubit-oscillator interactions
Mohammad Ayyash, Sahel Ashhab
The dispersive regime of -photon qubit-oscillator interactions is analyzed using Schrieffer-Wolff perturbation theory. Effective Hamiltonians are derived up to the second order…
Multimode Qubit-Conditional Operations via Generalized Cross-Resonance
Mohammad Ayyash
We present a general framework for generating single- and multimode qubit-conditional operations by extending cross-resonant driving to a generalized multimode scheme. This include…
Properties and dynamics of generalized squeezed states
Sahel Ashhab, Mohammad Ayyash
We analyze the properties and dynamics of generalized squeezed states. We find that, in stark contrast to displacement and two-photon squeezing, higher-order squeezing leads to osc…
