This method constitutes a breakthrough that has potentially transformative consequences for the future of photonics-based quantum computing.\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u201cOur results point to the possibility of building quantum computers using light by taking advantage of this entanglement,\u201d said\u0026nbsp;\u003Ca href=\u0022https:\/\/physics.gatech.edu\/user\/chandra-raman\u0022\u003EChandra Raman\u003C\/a\u003E, a professor in the\u0026nbsp;\u003Ca href=\u0022https:\/\/physics.gatech.edu\/\u0022\u003ESchool of Physics\u003C\/a\u003E.\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EQuantum computers have the potential to outperform their conventional counterparts, becoming the fastest programmable machines in existence. Entanglement is the key resource for building these quantum computers.\u0026nbsp;\u003C\/p\u003E\u003Cp\u003ELight has always been seen as ideal for quantum computing,\u0026nbsp;but it presents challenges. Photons don\u2019t interact with each other. \u201cIf I have two or more photons, it\u0027s extremely difficult to make them interact; they fly right by each other,\u201d said postdoctoral researcher Aniruddha Bhattacharya. \u201cThe key discovery here is we can entangle photons in a useful, controllable, and deterministic way.\u201d\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EThe researchers devised a protocol to create entanglement consistently. Their protocol makes use of a mathematical geometric structure known as non-Abelian quantum holonomy, which can entangle photons without requiring quantum measurements. Holonomy can be implemented with on-chip photonic devices, suggesting this protocol could be used to create scalable and integrable photonic quantum computers.\u003C\/p\u003E\u003Cp\u003EThe research\u2019s implications are staggering for the future of quantum computing. Photonic quantum computers work well at room temperature, are portable, and are more easily integrated with existent quantum communication systems and links. Quantum computing is the future of not just computing but innovation, and photons could unlock new frontiers.
