摘要

Abstract

Advancements in quantum optics and squeezed light generation have revolutionized various fields of quantum science over the past three decades

with notable applications such as gravitational wave detection. Here

we extend the use of squeezed light to the realm of ultrafast quantum science. We demonstrate the generation of the shortest ultrafast synthesized quantum light pulses spanning 0.33 to 0.73 PHz by a degenerate four-wave mixing nonlinear process. Experimental metrology results confirm that these pulses exhibit amplitude squeezing

which is consistent with theoretical predictions. Moreover

we observe the temporal dynamics of amplitude uncertainty of the squeezed light

demonstrating that quantum uncertainty of light is controllable and tunable in real time. Additionally

we demonstrate control over the quantum state of light by switching between amplitude and phase squeezing. Our ability to generate and manipulate ultrafast

squeezed

synthesized light waveforms with attosecond resolution unlocks exciting possibilities for quantum technologies

including petahertz-scale secure quantum communication

quantum computing

and ultrafast spectroscopy. As an example

we introduce an attosecond quantum encryption protocol leveraging squeezed synthesized light for secure digital communication at unprecedented speeds. This work paves the way for exploring quantum uncertainty dynamics and establishes the foundation for the emerging ultrafast and attosecond quantum science fields.
