>A topological quantum computer is a type of quantum computer proposed by Russian-American physicist Alexei Kitaev in 1997.[2] It utilizes quasiparticles, known as anyons, in two-dimensional systems. These anyons' world lines intertwine to form braids in a three-dimensional spacetime (one temporal and two spatial dimensions). These braids act as the logic gates of the computer. The primary advantage of using quantum braids over trapped quantum particles is enhanced stability. While small but cumulative perturbations can cause quantum states to decohere and introduce errors in traditional quantum computations, such perturbations do not alter the topological properties of the braids. This stability is akin to the difference between cutting and reattaching a string to form a different braid versus a ball (representing an ordinary quantum particle in four-dimensional spacetime) colliding with a wall.

i thought quantum computing was a scam, is it real now? have they been able to factorize anything above 12…
