This article will give an introduction to quantum computing with superconducting quantum circuits. More specifically, quantum computing with transmon qubits in circuit QED architecture. Nowadays, many Quantum processors use superconducting qubits like IBM Quantum, one of the well known Quantum Giant perfects in superconducting architecture. To understand Superconducting Qubits, let's first understand superconductors and why they play an important role in superconducting qubits.

Topics covered in this article:

1. What are Superconductors?
2. Josephson Junction
3. Superconducting Quantum Circuits: The Transmon qubit
4. Advantages of Superconducting Qubits
5. Disadvantages of Superconducting Qubits
6. Ongoing research in Superconducting Qubits

What are Superconductors?

In our day to day applications, we come across various conductors which are vital for everyday tasks. One common example everyone will be familiar with are copper and aluminium wires, which conducts electricity from the generator to our switchboards. Though these materials are excellent conductors for…
