The Jaynes–Cummings Model (JCM) has recently been receiving increased attention as
one of the simplest, yet intricately nonlinear, models of quantum physics. Emphasising the …

To harness the potential of a quantum computer, quantum information must be protected
against error by encoding it into a logical state that is suitable for quantum error correction …

The Kerr-cat qubit is a bosonic qubit in which multiphoton Schrödinger cat states are
stabilized by applying a two-photon drive to an oscillator with a Kerr nonlinearity. The …

We propose an autonomous quantum error correction scheme using squeezed cat (SC)
code against excitation loss in continuous-variable systems. Through reservoir engineering …

In circuit and cavity quantum electrodynamics devices where control qubits are dispersively
coupled to high-quality-factor cavities, characteristic functions of cavity states can be directly …

Mechanical degrees of freedom are natural candidates for continuous-variable quantum
