Dynamically protected cat-qubits with quantum superconducting circuits
I will present a new hardware-efficient paradigm for encoding, protecting and manipulating quantum
information in a quantum harmonic oscillator, more specifically a cavity mode.
While an initial scheme  has allowed us to encode the quantum information on
a four-component Schrödinger cat state , a continuous monitoring of
photon-number parity observable  should lead to a protected quantum memory
. After briefly presenting these results, I will elaborate on how through a
multi-photon driven dissipative process and quantum Zeno dynamics, one can
extend this scheme towards a new paradigm for universal quantum computation
with protected logical qubits .
