Distributed quantum metrology can enhance the sensitivity for sensing spatially distributed parameters beyond the classical limits. Here we demonstrate distributed quantum phase estimation with discrete variables to achieve Heisenberg limit phase measurements. Based on parallel entanglement in modes and particles...
Phase estimationDistributed quantum computingEntanglement fidelityQuantum Fourier transformIn the near-term, the number of qubits in quantum computers will be limited to a few hundreds. Therefore, problems are often too large and complex to be run on quantum devices. By distributing quantum algorithms ...

Quantum networks will provide unconditional security for communication, computation and distributed sensing tasks. We report on an experimental demonstration of private parameter estimation, which allows a global phase to be evaluated without revealing the constituent local phase values. This is achieved by...

In the framework of Russell’s circumplex model of emotions, we characterize NIAs emotional states with the help of arousal and valence variables which represent discrete quantum variables in our case. In24, we have shown that equilibrium phase transitions occurring in the social network system can...
