| Found in | Work cat: Xiong, F. A generalized noisy communication channel approach for quantum computing, 2013. Physical review. A, Feb. 2014: p. 022306-1 (Tractable simulation of error correction with honest approximations to realistic fault models. ... Quantum computing is the theory and practice of using systems which exhibit the properties of quantum mechanics to store and process information, allowing certain computational problems to be solved with greater speed than any known classical algorithm) Journal of computational and applied mathematics, Dec. 1, 2013: p. 15 (Quantum Computing (QC) is a new research field that has induced intense researches in the last decade, and that covers investigations on quantum computers and quantum algorithms. QC relies on the principles of quantum mechanics like qubit representation and superposition of states. QC is able to process huge numbers of quantum states simultaneously in parallel. QC brings new philosophy to optimization due to its underlying concepts) Webopedia, Jan. 28, 2015 (First proposed in the 1970s, quantum computing relies on quantum physics by taking advantage of certain quantum physics properties of atoms or nuclei that allow them to work together as quantum bits, or qubits, to be the computer's processor and memory. By interacting with each other while being isolated from the external environment, qubits can perform certain calculations exponentially faster than conventional computers) Metodi, T.S. Quantum computing for computer architects, 2006: p. iv (Quantum computation may seem to be a topic for science fiction, but small quantum computers have existed for several years and larger machines are on the drawing table. These efforts have been fueled by a tantalizing property: while conventional computers employ a binary representation that allows computational power to scale linearly with resources at best, quantum computations employ quantum phenomena that can interact to allow computational power that is exponential in the number of "quantum bits" in the system. Quantum devices rely on the ability to control and manipulate binary data stored in the phase information of quantum wave functions that describe the electronic states of individual atoms or the polarization states of photons) Quantum Artificial Intelligence Laboratory WWW home page, Jan. 28, 2015 (Quantum computing is based on quantum bits or qubits. Unlike traditional computers, in which bits must have a value of either zero or one, a qubit can represent a zero, a one, or both values simultaneously. Representing information in qubits allows the information to be processed in ways that have no equivalent in classical computing, taking advantage of phenomena such as quantum tunneling and quantum entanglement. As such, quantum computers may theoretically be able to solve certain problems in a few days that would take millions of years on a classical computer) Emerging trends in quantum computing, via WWW, Jan. 28, 2015 (Quantum computing (or quantum information processesing [sic]) uses qubits as its basic information unit) |
