Photons are a significant aspect of quantum computing. For instance with quantum dots.
**Quantum**dots can convert terahertz photons into visible light. This mechanism is used to develop a semiconductor-based room-temperature terahertz camera that can simultaneously record the field strength and polarization states of a terahertz beam. The proposed detector has fast speeds and can be manufactured at the wafer-scale.
