And last September, Christopher Monroe and his team at the University of Maryland in College Park were able to
entangle two qubits made of single ions.
As the chain segments relax further, G(t) decreases nearly monotonically with time for low molecular weight chains that do not
entangle. But for entangled systems, G(t) falls through a transition period to a zone marked by a relatively flat temporal response where the modulus value remains fixed.
The NIST experiments seek to
entangle atoms in such a way that measuring the energy level of one would reveal the energy level of another, even if they happen to be widely separated.
At the Institute of Quantum Optics and Quantum Information in Innsbruck, the team of physicists has now used laser light to
entangle 20 calcium atoms in an ion trap experiment and observed the dynamic propagation of multi-particle entanglement in this system.
Ref Joe Cortez will warn the British boxer against excessive holding after the Kiwi's camp raised fears Lewis would
entangle their fighter in his powerful arms.
