Multi-Qubit Entangling Measurements in Linear Optics - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240256935 titled 'Multi-Qubit Entangling Measurements in Linear Optics
The apparatus described in the patent application includes an optical circuit with an interferometer and a detector arrangement. The interferometer is designed to receive n dual-rail encoded photonic qubits, each encoded with probability amplitudes corresponding to the photon occupation of two orthogonal optical modes, where n is greater than 2. The interferometer interferes the n dual-rail encoded photonic qubits through specific beamsplitter interactions, resulting in 2n output optical modes. The detector arrangement includes photodetectors to measure the photon occupation of each of the 2n output optical modes.
- The apparatus utilizes an interferometer to process n dual-rail encoded photonic qubits.
- Each photonic qubit is encoded with probability amplitudes representing photon occupation of two orthogonal optical modes.
- Beamsplitter interactions are performed on specific modes of consecutive qubits within the interferometer.

Original Abstract Submitted
an apparatus includes an optical circuit with an interferometer and a detector arrangement. the interferometer is arranged to receive, as 2n input optical modes, n dual-rail encoded photonic qubits, each photonic qubit encoded as probability amplitudes corresponding to the photon occupation of two orthogonal optical modes, where n>2. the interferometer is arranged to interfere the n dual-rail encoded photonic qubits such that (i) a beamsplitter interaction is performed on the first mode of the first qubit and the second mode of the nqubit, and (ii) a beamsplitter interaction is performed on the second mode of the jqubit and the first mode of the (j+1)qubit for all j between 1 and nâ1. the interferometer is arranged to output 2n optical modes. the detector arrangement includes one or more photodetectors to measure a photon occupation of each of the 2n output optical modes.
