Objective
Superconducting quantum computers have the potential to solve certain complex problems exponentially faster than classical computers, enabling potential breakthroughs in basic science, applied chemistry, and material science. However, they require precise control over fragile quantum systems that are highly sensitive to environmental disturbances. These disturbances are causing errors that need to be detected and corrected. With current technology, this task comes with significant hardware overhead, typically requiring millions of physical qubits to perform useful calculations. This presents an unreasonable economic and environmental challenge for the development of quantum computers.
In TURQUOISE, I will adopt a novel approach by using noise-biased qubits to implement quantum error correction, instead of standard qubits with symmetric error rates. In noise-biased qubits, bit flips are a lot less frequent than phase flips, which allows for more hardware-efficient quantum error correction. 1) I will leverage the unique properties of fluxonium — a superconducting qubit with one of the highest coherence and control fidelity reported to date — to create a new qubit with a very large noise bias. This will be achieved by reaching a novel parameter regime with noise-resilient circuit designs. 2) I will explore entirely new control strategies that utilize the noise bias to perform multi-qubit operations. 3) I will then implement a logical qubit and evaluate its performance to demonstrate the potential of noise-biased architecture in shifting the paradigm of quantum computation.
The TURQUOISE project aims to deepen our understanding of quantum electrical circuits, qubit control, and quantum error correction, ultimately opening new horizons for practical quantum computing.
