Quantum computing has developed from mathematical applications of fundamental quantum mechanics to the realization of an actual multiple qubit computational platform, called IBM-Q, that is accessible to external users. I will give an overview of quantum computing methodologies but focus more specifically on IBM’s approach utilizing Josephson Junctions imbedded in resonator structures that operate at 10 mK. In addition to discussing the mathematical basis of quantum computing, I’ll describe several key quantum gates and how they are implemented in a quantum computer.
Qiskit, IBM’s platform that enables external users to write programs on IBM-Q will be discussed. I will finish by describing quantum transduction, a method that we are developing to enable blind computing and scaling using entangled photons for optical communication.
