Autonomous Quantum Error Correction and Application to Quantum Sensing with Trapped Ions

Understand

Quantum-enhanced measurements hold the promise to improve high-precision sensing ranging from the definition of time standards to the determination of fundamental constants of nature.

• However, quantum sensors lose their sensitivity in the presence of noise.
• To protect them, the use of quantum error correcting codes has been proposed.
• Trapped ions are an excellent technological platform for both quantum sensing and quantum error correction.
