supercomputers on every desktop. I mentioned earlier t today’s computers and consoles use processors t squeeze many tiny transistors into a small area. t five ransistors, eaciny tens of t on talking about t th.
No’s small, Quantum computing goes even smaller and uses tter, subatomic particles sucrons, ions and pons as transistors. In tum ors are knoum bits or qubits. icles as transistors? ticles possess certain be can not only be used to represent ter speak but to also to perform complex calculations orders of magnitude faster today’s computers. Again, let me briefly outline t alloing.
Atomic particles inct and opposite spin orientations t can eac ticle to effectively beransistor. Once a particle is isolated from its environment, it enters trange quantum state o as superposition, ations at once and can represent a mix of 1s and 0s. tring of particles in tate of superposition to simultaneously represent every possible combination of 1s and 0s. A quantum computer can t represent possible solutions to a problem in a single operation. today’s computers ion one after ther.
ticles in superposition can become entangled act. Entanglement means t one or more of ties become linked even ed. If one of ticles is knocked out of superposition into a definite state (a 1 or 0 as described earlier), ticle, no matter could be on tion at t in time and assumes tate. Since entanglement alloant particles to sate it effectively alloeleportation of states, or in teleportation o
