Quantum Computers : Where are the limits of human technology? And can we somehow avoid them? This is where quantum computers become very interesting.
In 1947, American computer engineer Howard Aiken said that just six electronic digital computers would satisfy the computing needs of the United States. Others have made similar errant predictions about the amount of computing power that would support our growing technological needs. Of course, Aiken didn’t count on the large amounts of data generated by scientific research, the proliferation of personal computersor the emergence of the Internet, which have only fueled our need for more, more and more computing power.
A traditional computer uses long strings of “bits,” which encode either a zero or a one. A quantum computer, on the other hand, uses quantum bits, or qubits. What’s the difference? Well a qubit is a quantum system that encodes the zero and the one into two distinguishable quantum states
