the spin value of electrons has NOTHING to do with how they are used in computers.jk22 said:If instead of electrons, which are spin 1/2 particles, we could use photons, which are spin 1, could we use this fact to have a three valued logic (1,0,-1) ?
In summary, we have demonstrated controlled integration of preselected nanowire-based single quantum emitters into photonic waveguides. Our novel technique enables scalable integration of selected sources in complex photonic architectures on a single chip. The integrated sources maintain their high optical quality in terms of single photon purity, line width, and intensity with a coupling efficiency to the photonic waveguide as high as 24%. Furthermore, we showed theoretically that for a suspended SiC waveguide, in conjunction with a 1D Bragg reflector, a unidirectional coupling efficiency greater than 86% can be realized. Coupling our quantum emitters to on-chip photonic cavities will allow to investigate the rich physics of cavity quantum electrodynamics, thus enhancing the spontaneous emission rate to accelerate the emission lifetime and approach Fourier-transform limited photons. Finally, by local tuning of the emission energy of single photon sources, indistinguishable photons can be generated as a necessary step toward on-chip optical quantum computation. 2016
A ternary photonic computer is a type of computer that uses light instead of electricity to process information. It utilizes ternary logic, which means it has three possible states (0, 1, and 2) instead of the traditional binary logic of two states (0 and 1).
A ternary photonic computer differs from a traditional computer in that it uses light instead of electricity to represent and process information. This allows for faster processing speeds and lower energy consumption.
Yes, there are several techniques being explored for building a ternary photonic computer. These include using photonic crystals, quantum dots, and nonlinear optical materials to manipulate and control light in order to perform logic operations.
A ternary photonic computer has the potential to be used in a variety of applications, including data processing, machine learning, and cryptography. It could also have benefits in fields such as medicine, astronomy, and telecommunications.
There are still many challenges and limitations to overcome in building a ternary photonic computer. These include finding suitable materials for manipulating light in a ternary system, developing efficient and reliable logic operations, and integrating photonic components with traditional electronic components.
