All modern personal computers including desktops, notebooks, smartphones, and tablets, are examples of general-purpose computers. General-purpose computing incorporates ‘Von Neumann’ approach, which states that an instruction fetch and a data operation cannot occur simultaneously. Therefore, being sequential machines, their performance is also limited.   On the other hand, we have …

Quantum computing has the potential to create new machines that can vastly exceed the capabilities of today’s most powerful supercomputers. A quantum computer harnesses quantum mechanics to deliver huge leaps forward in processing power. Instead of the binary bits used by digital computers, quantum computers use qubits – subatomic particles …
