In ensemble (or bulk) quantum computation, all computations are performed on an ensemble of computers rather than on a single computer. Measurements of qubits in an individual computer cannot be performed; instead, only expectation values (over the complete ensemble of computers) can be measured. As a result of this limitation on the model of computation, many algorithms cannot be processed directly on such computers, and must be modified. We provide modification of the fault tolerant quantum computation protocols to enable processing on ensemble quantum computers.

Improvements in computer efficiency are not always due to increasing computation speed. The mouse and GUI approach to OS’s actually slowed down computation, but sped up computing. This paper highlights the concept of Unconventional Virtual Computation (UVC). With the increasing virtualization of computers, and the recognition that this year’s virtual computers are as fast as the hardware computers of 10 years ago, it becomes clear that we are only limited in our modes of computation by our imagination. A form of UVC is presented called Pulsed Melodic Affective Processing, which utilizes melodies to perform affective computations. PMAP makes computation more human-friendly by making it audible – a PMAP data stream sounds like the emotion it represents. A hybrid computation system is presented combining UVC PMAP with a Photonic Quantum Computer, in which the PMAP musico-logic circuit keeps the QC in a state of entanglement.

Since last years, computers reduce the human efforts and give improvement in its performance day by day.Quantum computers are those computers who perform computing which is based on the phenomenon called Quantum Mechanics.It is a fusion of classical computing which we were using now days, physics and mathematics.And the computing they performed by integrating these fields is termed as Quantum Computing.Quantum computers perform their computing on the basis of the microscopic particles like ions, photons, electrons, protons, neutrons etc which ultimately give exponentially high computation power and other advantages too like less consumption of electricity which we will discuss in the same paper in brief over the classical computers, which we were using till day.In this paper we will briefly explain the quantum computers, its history, its properties in which its computing is based upon, its advantages& disadvantages, its limitation, its real world application, the difference between classical computers and Quantum computers and the challenges it faced and at last we conclude it with its future scope.
