Abstract: A method is provided for deterministically generating a photonic resource state for computational quantum computing. The method includes producing a sequence of emitted photonic qubits. The sequence of emitted photonic qubits is directed to an optical circulator of a passive entanglement component. The passive entanglement component includes the optical circulator, a delay line, and a Controlled-Z (CZ) gate.

The CZ gate entangles the sequence of emitted photonic qubits with the sequence of reflected photonic qubits. The optical circulator directs a resource state generated from the sequence of reflected photonic qubits entangled with the sequence of emitted photonic qubits to an output of the passive component. The resource state is emitted as a sequence of entangled photonic qubits.
