Photonic Quantum Computing is a variant of quantum computing that uses individual particles of light (photons) as qubits instead of superconducting circuits or trapped ions.
Traditional computing faces limitations with certain complex problems, such as large-scale optimization or simulating quantum systems. Photonic quantum computers offer a potential solution by leveraging the unique properties of photons for efficient computation at scale.
In photonic quantum computers, information is encoded in the state of photons. These states are manipulated using programmable interferometers to create entangled photon pairs on demand. The computation process involves routing these photons through a network of optical elements and measuring their final state to extract computational results.
The manufacturing process involves creating and manipulating individual photons using precise optical components like waveguides, mirrors, and beam splitters. These components are often fabricated using semiconductor or nanophotonic techniques.
Building a photonic quantum computer requires setting up an array of optical elements to route and manipulate photons. This includes generating squeezed-light states, routing them through interferometers, and measuring the final state to extract computational results.
