Boson Sampling is a specialized model of quantum computation that involves sampling from the probability distribution of identical bosons (typically photons) scattered through a linear optical network. This quantum approach is designed to perform a tasks that are believed to be computationally intractable for classical computers, and in this way open the door to achieving quantum computational advantages.
How Does Boson Sampling Work?
- Photon Generation: Creating a specific number of indistinguishable photons
- Linear Optical Quantum Network: Passing photons through a complex network of beam splitters and phase shifters
- Quantum Interference: Leveraging the interference of photons as they propagate through the network
- Quantum Output Detection: Measuring the where the photons emerge at the output ports
