Erasing memory – Protecting Quantum Coherence and Entanglement
Abstract: In a quantum measurement, an operator projects the system into one of its eigenstates with a specific eigenvalue as the readout. Once the measurement is done, the unknown initial state of t...

Quantum Journal Club: Entanglement of Light-Shift Compensated Atomic SpinWaves with Telecom Light
Abstract: Entanglement of a 795 nm light polarization qubit and an atomic Rb spin-wave qubit for a storage time of 0.1 s is observed by measuring the violation of Bell’s inequality (S ¼ 2:65 0:12)...
