## What is/are Ultrafast Quantum?

Ultrafast Quantum - Direct imaging of the ultrafast quantum motion of valence electrons in molecules is essential for understanding many elementary chemical and physical processes.^{[1]}Among them, surface plasmon (SP) sources based on inelastic electron tunneling (IET) have been demonstrated as an appealing candidate owing to the ultrafast quantum-mechanical tunneling response and great tunability.

^{[2]}This technique will lead to ultrafast quantum computation.

^{[3]}Plexcitonic strong coupling between a plasmon-polariton and a quantum emitter empowers ultrafast quantum manipulations in the nanoscale under ambient conditions.

^{[4]}A promising scheme based on the regime of stimulated Raman Λ-type transitions between qubit states via upper-lying levels is suggested in order to provide ultrafast quantum operations on the picosecond time scale.

^{[5]}This robust and general finding enables the simulation of electrical transport from light-induced Floquet-Bloch bands in an experimentally relevant parameter regime and creates a pathway to designing ultrafast quantum devices with Floquet-engineered transport properties.

^{[6]}Coherent two-dimensional spectroscopy is a powerful tool for probing ultrafast quantum dynamics in complex systems.

^{[7]}This is the foundation of many quantum optical applications ranging from secure communication to ultrafast quantum computing [2].

^{[8]}We show that the DCE is a fundamental limitation for standard quantum protocols based on quantum Rabi oscillations, implying that new schemes are required to implement high-fidelity ultrafast quantum gates.

^{[9]}The coupling also exceeds the mechanical thermal decoherence rate, enabling new applications in ultrafast quantum state transfer and entanglement generation.

^{[10]}This, however, poses the challenge of designing specific optimal molecular structure for which the processes of ultrafast quantum coherence and electron transport are not so well understood.

^{[11]}These transitions are of interest for ultrafast quantum control as the bandwidth of the control pulses needs to be less than the transition frequency.

^{[12]}Simulating ultrafast quantum dissipation in molecular excited states is a strongly demanding computational task.

^{[13]}This work provides a robust approach to measure and analyse ultrafast quantum dynamics in complex nanosystems.

^{[14]}Verdozzi, and many others entering the field, has allowed for an unexpected burst of activity in computational studies of ultrafast quantum dynamics.

^{[15]}Advances in the development of robotics, artificial intelligence (AI), and high capacity ultrafast quantum computers (QC) greatly enhance the sophisticated control and logical development of extra-solar system studies.

^{[16]}High-quality results on subpicosecond intraband relaxation dynamics after single-electron excitation motivate a broad variety of future experiments in ultrafast quantum optics and few-fermion quantum dynamics.

^{[17]}This vital step towards strong-field ultrafast quantum electrodynamics unravels information inaccessible by conventional approaches and leads to the development of a new class of nonclassical light sources.

^{[18]}As conventional electronic is approaching its ultimate limits, tremendous efforts have been taken to explore novel concepts of ultrafast quantum control.

^{[19]}Introduction of plasmonics to ultrafast quantum control may resolve these issues and open a new avenue toward "controlled ground-state chemistry".
