Characterization of Arbitrary-Order Correlations in Quantum Baths by Weak Measurement
Characterization of Arbitrary-Order Correlations in Quantum Baths by Weak Measurement
Correlations of fluctuations are the driving forces behind the dynamics and thermodynamics in quantum many-body systems. For qubits embedded in a quantum bath, the correlations in the bath are the key to understanding and combating decoherence -a critical issue in quantum information technology. However, there is no systematic method for …
