Scalable Fault-tolerant Quantum Computation with Kerr-Cats

Presenting Author: Shruti Puri , Yale University

With fault-tolerant QEC it is possible to solve a computational problem accurately by transforming a many-body quantum state with a sequence of faulty operations on imperfect quantum hardware. However, the enormous overhead cost of fault-tolerant protocols is the key bottleneck in practical realization of quantum computers. In this talk I will present the superconducting Kerr-cat qubit architecture. This qubit is realized in a parametrically driven non-linear oscillator and has some in-built protection against noise. Finally, I will discuss how this protected cat-qubit can significantly reduce the overheads for fault-tolerant QEC.
