Hamiltonian tomography by the quantum quench protocol with random noise

چکیده
In this article, we introduce a framework for Hamiltonian tomography of multi-qubit systems with random noise. We adopt the quantum quench protocol to reconstruct many-body by local measurements that are distorted unitary operators and time uncertainty. particular, consider transverse field Ising Hamiltonians describing interactions two spins $1/2$ three-qubit heteronuclear system within radio-frequency field. For sample Hamiltonians, report fidelity reconstruction versus amount noise quantified parameters. Furthermore, discuss correlation between accuracy number pairs states involved in framework. The results provide valuable insight into robustness against

Random Hamiltonian Models and Quantum Prediction Algorithms
This paper describes an algorithm for selecting a consistent set within the consistent histories approach to quantum mechanics and investigates its properties. The algorithm select from among the consistent sets formed by projections defined by the Schmidt decomposition by making projections at the earliest possible time. The algorithm unconditionally predicts the possible events in closed quan...
متن کاملFault tolerant quantum key distribution protocol with collective random unitary noise
We propose an easy implementable prepare-and-measure protocol for robust quantum key distribution with photon polarization. The protocol is fault tolerant against collective random unitary channel noise. The protocol does not need any collective quantum measurement or quantum memory. A security proof and a specific linear optical realization using spontaneous parametric down conversion are given.
متن کاملTesting quantum adiabaticity with quench echo
Adiabaticity of quantum evolution is important in many settings; one example is adiabatic quantum computation (AQC). Nevertheless, to date, there is no effective method available for testing the adiabaticity of the evolution for the case where the eigenenergies of the driven Hamiltonian are not known. We propose a simple method for checking the adiabaticity of a quantum process for an arbitrary...
متن کاملTomography by noise.
We present an efficient and robust method for the reconstruction of photon number distributions by using solely thermal noise as a probe. The method uses a minimal number of precalibrated quantum devices; only one on-off single-photon detector is sufficient. The feasibility of the method is demonstrated by the experimental inference of single-photon, thermal. and two-photon states. The method i...
متن کاملA qutrit Quantum Key Distribution protocol with better noise resistance
The Ekert quantum key distribution protocol [1] uses pairs of entangled qubits and performs checks based on a Bell inequality to detect eavesdropping. The 3DEB protocol [5] uses instead pairs of entangled qutrits to achieve better noise resistance than the Ekert protocol. It performs checks based on a Bell inequality for qutrits named CHSH-3 and found in [10, 13]. In this paper, we present a ne...
