ABSTRACT
Quantum computing is a very active field producing many publications and varied perspectives. A quantum computer, as the name suggests, is a computer that can operate at the quantum level thus offering enormous improvements in energy consumption and size reductions. Significant size reductions and the use of photons should also lead to vast improvements in computational speed. The concept of a quantum computer goes beyond physical computers and seeks to offer an alternative universal computer. It does so by utilizing analogs to bits known as qubits. The interferometric computer is a macroscopic apparatus that allows the control of photon propagation via the probabilistic laws of quantum mechanics. The term quantum computer, however, applies to devices at the atomic scale that can be used to control the emission and/or propagation of quantum radiation obeying quantum logic rules.
