Experimental Control of Quantum-Mechanical Entanglement in an Attosecond Pump-Probe Experiment

Experimental Control of Quantum-Mechanical Entanglement in an Attosecond Pump-Probe Experiment Entanglement is one of the most intriguing aspects of quantum mechanics and lies at the heart of the ongoing second quantum revolution, where it is a resource that is used in quantum key distribution, quantum computing, and quantum teleportation. We report experiments demonstrating the crucial role that entanglement plays in pump-probe experiments involving ionization, which are a hallmark of the nove...
