Traditional qubits are encoded in discrete two-level systems. Instead, we can encode quantum information in complex multiphoton states of harmonic oscillators. By selecting multiphoton states with particular symmetries, we can protect these bosonic qubits against noise and decoherence.
We are developing a new generation of bosonic qubits. We will use cutting-edge hardware and new quantum error correction codes to reach new regimes in qubit storage times and gate fidelities.
Stay tuned for updates!
