Programmable entangled qubit states on a linear-optical platform
We present an experimental platform for linear-optical quantum information processing. Our setup utilizes multiphoton generation using a high-quality single-photon source, which is demultiplexed across multiple spatial channels, a custom-designed, programmable, low-loss photonic chip, and paired wit...

| description | We present an experimental platform for linear-optical quantum information
processing. Our setup utilizes multiphoton generation using a high-quality
single-photon source, which is demultiplexed across multiple spatial channels,
a custom-designed, programmable, low-loss photonic chip, and paired with
high-efficiency single-photon detectors. We demonstrate the platform's
capability in producing heralded arbitrary two-qubit dual-rail encoded states,
a crucial building block for large-scale photonic quantum computers. The
programmable chip was fully characterized through a calibration process that
allowed us to create a numerical model accounting for fabrication imperfections
and measurement errors. As a result, using on-chip quantum state tomography
(QST), we achieved high-fidelity quantum state preparation, with a fidelity of
98.5\% specifically for the Bell state. |
