An elementary quantum network of entangled optical atomic clocks
Demonstration of entanglement-enhanced frequency comparison of two optical atomic clocks based on the 674nm quadrupole transition of 88Sr+ ions, which are linked by a quantum-optical fibre link (≈2 m long). We show that the use of an entangled state reduces the measurement uncertainty by nearly √2 ,...
