Magnetic Computer 

  Quantum Computer -  As mentioned earlier the quantum computers work on the basis of quantum movements and it works on the basis of qubits whereas classic computers work on the basis of Bits and Bytes. That's not all quantum computers can have 1s and 0s both at the same time due to the quantum nature. Due to this superposition, quantum computer processing is double that of the classic computer. There is a lot of changes in processing the quantum computer as compared to the normal computer, the very first thing is the programming language, IDE, and SDK (like Qiskit) used to program all the processes in the device, the hardware requirements ( As the quantum computer isn't that developed so it is too much expensive and large that a single individual can't handle in a single room. ). Now as said above does this means that the quantum computer is eligible to be the future of technology or is there any other contender for it. 

Magnetic Computer -  Talking about the magnetic computer is just like the Tesla car of the computer world, What does this mean? Just like tesla manufactures electric cars with the technology of using electric batteries, in the same way, magnetic computers too work but with some different concept. In magnetic computers, the electrons are made to spin on the solid-state due to which we can say that the magnetic computers work on the concept of spintronics. As a result, spintronics results in a reduction or in some cases there is no use of electricity for the computer to work ( as the spin creates the massive amount of energy of electromagnetic waves which results in a reduction in the use of normal electric power just like classic computers ). As in this concept, we can see that the magnetic computers almost work the same as quantum then what's the difference? Spintronics contributed to the creation of the giant-magneto resistive (GMR) sandwich structure, which is used in industry as a read head and memory-storage cell and is made up of alternating ferromagnetic and non-magnetic metal layers. The device resistance changes based on the relative orientation of the magnetizations in the magnetic layers, ranging from low to high (parallel magnetizations) (antiparallel magnetizations). Changes in resistance (also known as magnetoresistance) are used to detect changes in the magnetic field. Electron spin is a magnetic field that can travel in either an up or down direction. This adds two extra binary states to the traditional high and low logic values represented by simple currents. A bit can have four states when the spin state is included: up-high, up-low, down-high, and down-low. These four states are analogous to quantum bits, or qubits. That's not all the magnetic waves or the ripples which have the very less amount of wavelength when collectively spin are called magnons. This means there are tons of electrons in a solid-state in spintronics so this forms a large number of magnons that create energy. With this said there was a team of MIT scientists who experimented with the spintronics (which we will be going through in the next post. ) So for now what do you think which computer has the upper hand for the future run?
