Molecular processes as quantum information resources

Area of Science:

• Quantum Information Science
• Molecular Quantum Dynamics
• Quantum Thermodynamics

Background:

• Theoretical research highlights molecular processes as potential quantum information resources.
• Homonuclear dimer (diatom) dissociation and atom-pair collisions are key processes.
• Quantum entanglement, specifically translational (EPR-like) entanglement, is central.

Purpose of the Study:

• To present a perspective on theoretical research concerning molecular processes as quantum information resources.
• To demonstrate how specific molecular processes can reveal and utilize quantum entanglement.
• To explore the quantum thermodynamic implications of these entangling molecular processes.

Main Methods:

• Theoretical analysis of homonuclear dimer dissociation (half-collision) and atom-pair collisions.
• Investigating the role of electronic-state excitation in diatomic systems.
• Examining the interaction of dissociated entangled diatoms with a cavity field.

Main Results:

• Controlled diatom dissociation and atom-pair collisions reveal translational (EPR-like) entanglement.
• This entanglement enables molecular wave packet teleportation.
• Fluorescence from excited diatom dissociation acts as an entanglement witness.
• Entangling processes exhibit anomalous quantum thermodynamics, including cavity field temperature enhancement.

Conclusions:

• Molecular processes offer a viable platform for quantum information processing.
• Entanglement revealed in molecular collisions has practical applications in quantum teleportation.
• Quantum entanglement in molecular systems leads to unique thermodynamic phenomena.
