• Abstract: The distinction between chiral, trivial helical, and topological helical edge modes can be effectively made using quantum noise measurements at finite temperatures. Quantum noise measurements consist of mainly two components. The first is thermal noise, whose provenance is thermal fluctuations, and the second is shot noise, whose origin is the quantum nature of charge particles. Studying these edge modes at finite temperatures is important as it more accurately reflects the conditions in real-world experiments. Additionally, we have verified that our results for finite temperature quantum noise correlations are valid at finite frequencies too.

• Effects of Temperature Fluctuations on Charge Noise in Quantum Dot Qubits [0.0]
  Silicon quantum dot qubits show great promise but suffer from charge noise with a 1/falpha spectrum, where f is frequency and alpha lesssim 1. We find that noise with a $1/falpha$ spectrum with $alpha lesssim 1 down to low frequencies, the duration of temperature fluctuations must be comparable to the inverse of the lowest frequency at which the noise is measured. We conclude that temperature fluctuations in a 2DEG sub-bath would require an unphysically long duration to be consistent with experimental measurements of 1/f-like charge noise in quantum dots

• Ultimate precision of joint parameter estimation under noisy Gaussian environment [0.0]
  In some specifics quantum protocols without environmental noise, the ultimate sensitivity of a multiparameter quantum estimation can beat the standard quantum limit. We focus on a general two-mode mixed squeezed displaced thermal state, after reducing it to various Gaussian probes states. We find that when the entangled states, two-mode pure squeezed vacuum and two-mode mixed squeezed thermal, are employed as probes states, the upper and bottom bound of HCRB beats the standard quantum limit in the presence of a noisy environment.
