Quantum Computing

Entangling Qubits

When programming with traditional languages, you can safely ignore the underlying digital electronics. But with quantum computing, the quantum mechanical principles are always lurking around. In fact, quantum superposition comes with its own unique by-products that entangle or force qubits to depend on each other. Qubit states are, of course, coordinated by the quantum gates that operate on them. That is, their states are determined by the sequence of gates that act on them, just as in classical computers. But, entanglement ties the qubits in a deeper way that has more to do with quantum mechanics than Boolean logic. If these bindings aren’t properly accounted for in our programs, this oddity can interfere with collapsing the ...
