Lateral computing
In a quantum computer, the fundamental unit of information (called a quantum bit or qubit), is not binary but rather more quaternary in nature. This qubit property arises as a direct consequence of its adherence to the laws of quantum mechanics, which differ radically from the laws of classical physics. A qubit can exist not only in a state corresponding to the logical state 0 or 1 as in a classical bit, but also in states corresponding to a blend or quantum superposition of these classical states. In other words, a qubit can exist as a zero, a one, or simultaneously as both 0 and 1, with a numerical coefficient representing the probability for each state. A quantum computer manipulates qubits by executing a series of quantum gates, each a unitary transformation acting on a single qubit or pair of qubits. In applying these gates in succession, a quantum computer can perform a complicated unitary transformation to a set of qubits in some initial state.
Cobalt Qube
The Qube 2700 was the first product released by Cobalt Networks in 1998. Mark Orr, one of the Cobalt Networks' CEOs, came up with the cobalt color. The green LED in the front was Bill Scott's idea. The 2700 was not a development version number but came from the atomic number of cobalt, 27. The Qube 2700 used the RM5230 microprocessor.
