a device that harnesses physical phenomenon unique to quantum mechanics (especially quantum interference) to realize a fundamentally new mode of information processing
a device that relies on distinctly quantum mechanical resources such as superposition and entanglement
a machine that uses uniquely quantum-mechanical effects, especially interference, to perform wholly new types of computation that would be impossible, even in principle, on any Turing machine and hence on any classical computer
a machine which can operate in parallel on all its possible inputs at once, and can be programmed much like a conventional digital computer
a massively parallel machine that can execute classically exponentially difficult algorithms (e
a material device which uses its quantum properties to compute a given problem
an apparatus in which the states of the qubits can be made to evolve in a deterministic way and thereby carry out a computation by operating on the qubits with quantum logic gates
a new type of computer which can efficiently solve complex problems such as prime factorization
a new type of computer which can solve problems such as factoring and database search very efficiently
a (so far) hypothetical device which exploits the strange behavior of the quantum world to perform interesting computational tasks
a (so far) hypothetical device which would exploit the strange properties of quantum mechanics to perform qualitatively new kinds of computations -- most notably factoring large integers in polynomial time
a very powerful computer based on quantum physics. It will have the capacity to calculate more the one problem at a time.
A proposed computer that would exploit the quantum mechanical nature of particles, such as electrons or atomic nuclei, to manipulate information as quantum bits, or qubits. Whereas an ordinary bit has at any time a value of either 0 or 1, a qubit can also take on both values at once. Because a quantum computer can act on these multiple states simultaneously, it is potentially many times as powerful as a conventional computer.

A quantum computer is any device for computation that makes direct use of distinctively quantum mechanical phenomena, such as superposition and entanglement, to perform operations on data. In a classical (or conventional) computer, the amount of data is measured by bits; in a quantum computer, the data is measured by qubits. The basic principle of quantum computation is that the quantum properties of particles can be used to represent and structure data, and that quantum mechanisms can be devised and built to perform operations with these data."http://www.media.mit.edu/physics/publications/papers/98.06.sciam/0698gershenfeld.html Quantum Computing with Molecules" article in Scientific American by Neil Gershenfeld and Isaac L.
