Quantum Physics. Quantum computing. First Commercial Quantum Computer Is Sold. Quantum computer. Study of a model of computation Quantum computing is the use of quantum phenomena such as superposition and entanglement to perform computation.
Computers that perform quantum computations are known as quantum computers.[1]:I-5 Quantum computers are believed to be able to solve certain computational problems, such as integer factorization (which underlies RSA encryption), substantially faster than classical computers. The study of quantum computing is a subfield of quantum information science. The universe is a quantum computer. Seth Lloyd WHAT is the universe made of?
Matter or energy? Particles or strings? According to physicist Vlatko Vedral's appealing new book, it is made, at bottom, of information. In other words, if you break the universe into smaller and smaller pieces, the smallest pieces are, in fact, bits.
