On Superconducting Quantum computer

In 2008 Dr. Kim invented Cooper Pair wavefunction approach to the Josephson effect and discovered Threshold resistance, which was discovered experimentally already, but hidden in the literature, because people couldn’t understand the phenomenon. He also found more accurate formula for temperature dependence of the Josephson supercurrent. Prof. Van Duzer, a Pioneer in Superconducting Digital Electronics, and other physicists provided positive comments on his discoveries.

He hasn’t finished the theory for the AC Josephson effect in the presence of the external voltage through the Josephson junction. Note that Likharev claimed that AC Josephson effect has more problems than answers in his review paper.

Superconducting qubits are based on the Josephson effect, and the AC Josephson effect is crucial for controlling qubit states. When there is no reliable theory for the AC Josephson effect, what is the point of making larger number of qubits and producing superconducting quantum computer? It will be impossible to distinguish the origin of errors, whether they are due to qubit errors or due to theoretical errors?

In this context, it can be understood why Google shut down their superconducting 105-qubit chip, Willow.

We introduce an approach to the Josephson effect in the superconductor-insulator-superconductor (SIS) tunnel junctions. The Josephson coupling energy is calcula

Why Dr. Kim started Cutting Edge Superconductors?

=> essay recommended by Liberty Ventures and posted on LinkedIn.

Why did I start my company, Cutting Edge Superconductors? I discovered many new phenomena in Mathematical Physics and Material Science, especially in Superconductivity. But the problem is, I and Prof. A. W. Overhauser found that people made mistakes in superconductivity theory, including Nobel Laure...
