A major challenge in performing quantum error correction (QEC) is implementing reliable measurements and conditional feed-forward operations. In quantum computing platforms supporting unconditional qubit resets, or a constant supply of fresh qubits, alternative schemes which do not require measurements are possible. In such schemes, the error correction is realized via crafted coherent quantum feedback.

Popular Summary Accessing the quantum state of electromagnetic fields and its fluctuations on ultrashort timescales is a formidable challenge for experiments. Yet, doing so, in particular for broadband quantum pulses, is key for the further development of quantum optics. Progress in this field requires the theoretical and experimental capabilities to completely characterize pulsed quantum states, a task known as quantum state tomography.
