Advances and Challenges in Quantum Error Correction

Prof. Misha Lukin (Harvard), Dolev Bluvstein (Harvard), and Harry Zhou (Harvard and QuEra), co-authors of a recent Harvard-led work in quantum error correction, published in Nature, are interviewed by Yuval Boger. The authors highlight the evolution from physical to logical qubits and the realization of up to 48 logical qubits and emphasize the significance of error correction in maintaining quantum states in large systems. They discuss using neutral atoms and optical tweezers in their experiments, the scalability of their methods, and the potential for practical applications. The conversation touches on future directions and much more.
