Quantum Computers, first proposed by Richard Feynman, part of the Manhattan Project, may be coming closer to creation and use. These high-tech computers can be many times better-performing than regular ones, yet are also hard to make..
Quantum Computers work by using electron spins, with positive or negative values, instead of ones or zeros by classical computers. Another comparison is that classical computers store data in "bits", while quantum computers store it in "qubits". A qubit contains both values, instead of only one, and will only contain one when it is acted on.
Qubits have an advantage over bits, in the property that 1000 bits will store 1000 pieces of data, while 1000 qubits will store up to 2^1000 pieces of data simultaneously. The only problem, is that managing 1000 qubits is infinitely harder than 1000 bits. The qubits can undergo unwanted reactions with their surroundings, causing the system to destabilize.
New research uses manipulation of electrons by electric fields. Electric fields are expected to be precise enough to let the calculations that can be done finish, which their magnetic counterparts, previously used in experiments, could not.
Quantum computers, could, in fact, be used to calculate so fast, that the user could break into any security at ease. Any company with a quantum computer could easily gain an edge on competitors, nations could find other's secrets with ease. It would be an electric spying device without contest.
The technical problems in making quantum computers work are difficult, and the consequences of success would change the world. Also, it is not entirely sure that making these computers is possible, but we plan to find out. By using electric fields, the new models could be the breakthrough that is needed to make quantum computers a feasible tool.
