چکیده

We extend recent results on the quantum Hoeffding bound from the i.i.d. setting to a setting when both the null-hypothesis and the counter-hypothesis can be correlated states of a spin chain. The key property in the extension is a certain factorization property of the states. Typical examples with this property are the global Gibbs states of translationinvariant finite-range interactions.

The Converse Part of The Theorem for Quantum Hoeffding Bound

We prove the converse part of the theorem for quantum Hoeffding bound on the asymptotics of quantum hypothesis testing, essentially based on an argument developed by Nussbaum and Szkola in proving the converse part of the quantum Chernoff bound. Our result complements Hayashi’s proof of the direct (achievability) part of the theorem, so that the quantum Hoeffding bound has now been established.

Thermal negativity in a two qubit XXX and XX spin chain model in an external magnetic field

In this paper we studied the thermal negativity in a two-qubit XX spin ½ chain model and XXX spin1/2 chain model(isotropic Heisenberg model)spin-1/2 chain subjected to an external magnetic field inz direction. We calculate analytical relation for the thermal negativity for two qubit XX and XXX spinchain models in the external magnetic field. Effects of the magnetic field and temperature on then...

Quantum hypothesis testing with group symmetry

The asymptotic discrimination problem of two quantum states is studied in the setting where measurements are required to be invariant under some symmetry group of the system. We consider various asymptotic error exponents in connection with the problems of the Chernoff bound, the Hoeffding bound and Stein’s lemma, and derive bounds on these quantities in terms of their corresponding statistical...

Thermal effect and role of entanglement and coherence on excitation transfer in a spin chain

We analyze the role of bath temperature, coherence and entanglement on excitation transfer in a spin chain induced by the environment. In Markovian regime, we show that coherence and entanglement are very sensitive to bath temperature and vanish in time in contrary to the case of having zero-temperature bath. That is while, finding the last qubit of the chain in excited state increases by incre...

اثرات ناخالصی‌های مغناطیسی بر عبور الکترون از یک نانو حلقه کوانتومی

In this paper we study the Aharonov-Bohm oscillations of transmission coefficient for an electron passing through a quantum nanoring with two identical magnetic impurities using quantum waveguide theory. It is shown that the Aharonov-Bohm oscillations are independent of the coupling constant between the electron and magnetic impurities for the singlet spin state of impurities, while for the o...
