Superconducting Quantum Computing

Speaker:

Matthew Beck, IBM research staff member

 

Description:

Superconducting quantum bits ("qubits") are the leading candidate towards creating a fault-tolerant quantum processor. In this talk, I will review the physics that makes such devices possible. Starting with a brief review of BCS theory and Josephson physics, I will show how one can effectively and correctly quantize superconducting circuits into individual degrees of freedom and ultimately computational basis states. From here, I will discuss the engineering of the most successful superconducting qubit to date, the transmon. I will then describe the control and readout of transmon qubits at the individual and two-qubit gate level. Finally, I will provide a few brief thoughts on what is required to build 1000+ qubit fault tolerant processors.
