CHARLOTTESVILLE, Va., Nov. 3, 2021 — Researchers at the University of Virginia developed a tiny optical frequency comb, or microcomb, that uses two-mode squeezing to create unconditional entanglement between continuous optical fields. The miniature, chip-based device lays the groundwork for mass production of deterministic quantum frequency combs that could see use in quantum computing, quantum metrology, and quantum sensing. The microcomb is designed for quantum information protocols based on continuous-variable entangled states that generate qumodes (entangled states) for entire optical fields rather than single photons....Read full articleRelated content from Photonics MediaARTICLESMiniature Frequency Combs Could Confirm, or Refute, Quantum TheoriesResearchers at Stanford University have observed the quantum properties of soliton frequency combs, opening the door to confirm quantum theories.
