HECK NO! An optics computer is a computer running on light, but a quantum computer is a computer where most components are at a quantum-Hall state of matter (hey did you know that there are more than 15 states of matter). In other words, optic computer=light, quantum computer=weird.

IBM was known as Quantum Computer Services, Inc.

A quantum computer uses quantum-mechanical phenomena to manipulate data. Still in its infancy, quantum computing is the subject of much research activity funded by both military and civilian organizations.

The Quantum computer is used for Quantum mechanics. A regular computer or laptop has restrictions due to physics but a Quantum computer performs faster with being able to be in more states at once.

The most important gate is probably the CNOT gate, because combined with qubit superpositions and measurements, it forms the basis of a universal quantum computer. A quantum computer uses CNOT gates instead of conventional logic gates (such as NAND) because quantum mechanics requires that quantum computations be reversible.
