Curator's Take
This perspective article highlights an exciting convergence between electron microscopy and quantum control, where researchers are using electron beams as precision tools to both probe and manipulate quantum coherence in semiconductor qubits. The work is particularly significant because it offers a new pathway to understand and control the delicate quantum-environment interactions that often plague semiconductor quantum computing platforms with decoherence issues. By harnessing electron beams to actively manipulate entanglement and correlations, this approach could lead to better strategies for protecting quantum information in solid-state systems. The research represents a compelling fusion of established microscopy techniques with cutting-edge quantum technologies, potentially opening doors to more robust table-top quantum computers based on semiconductor architectures.

Summary
Examining and controlling the interaction between semiconductor quantum qubits and their environment can boost semiconductor quantum technologies, which have many applications in table-top quantum computing hardware. Electron beams in electron microscopes have opened up a new avenue for the quantum-coherent probing of semiconductor excitations and strong-coupling effects. Here, I provide a brief overview of recent advancements in electron-beam probes for investigating quantum coherence in semiconductors and two-dimensional materials, complemented by my perspective on using electron beams to manipulate the entanglement and correlations between quantum systems.
