Making robust integrated photonic qubits
Nature, Published online: 04 June 2025; doi:10.1038/d41586-025-01696-7High-performance photonic integrated chips have been demonstrated that generate robust optical quantum bits called Gottesman–Kitaev–Preskill qubits. One such chip has been used to realize qubit states, reconstruct the quantum features of these states and verify the quality of the qubits.
