Quantum Mechanics Explained

The Quantum Computer

I’ve tried to grasp the concept and bring the “quantum computer” down to laymen’ terms. It always amazes me, how like terms are used to provide the definition of a process or the device being described. If you don’t know what the quantum mechanical phenomena are, and you have no idea to begin with, of what superposition and entanglement are as it relates to quantum mechanical phenomena, and similar terms are used to describe the process, then you are in a round robin feedback loop world of explanations.


A quantum computer is a device for computation that makes direct use of quantum mechanical phenomena, such as superposition and entanglement, to perform operations on data. The basic principle behind quantum computation is that quantum properties can be used to represent data and perform operations on these data.

And for example:


Quantum Superposition:
Quantum superposition is the fundamental law of quantum mechanics. It defines the allowed state space of a quantum mechanical system.



Quantum entanglement is a possible property of a quantum mechanical state of a system of two or more objects in which the quantum states of the constituting objects are linked together so that one object can no longer be adequately described without full mention of its counterpart — even though the individual objects may be spatially separated. This interconnection leads to non-classical correlations between observable physical properties of remote systems, often referred to as nonlocal correlations.

There has got to be something written that doesn’t require a phd (pardon the PHDs out there) to understand; if you know what I mean.
