Adiabatic quantum state transfer in non-uniform triple-quantum-dot system
Adiabatic quantum state transfer non-uniform triple-quantum-dot system

2010/11/5
We introduce an adiabatic quantum state transfer scheme in a non-uniform coupled triple-quantum-dot system. By adiabatically varying the external gate voltage applied on the sender and receiver, the e...
Fano type quantum inequalities in terms of $q$-entropies

Generalizations of the quantum Fano inequality are considered. The notion of $q$-entropy exchange is introduced. This quantity is concave in each of its two arguments. For $q\geq0$, the inequality of ...

In this paper, we note that there are two different types of inconsistencies of quantum adiabatic theorem in work of K. P. Marzlin and B. C. Sanders [Phys. Rev. Lett. 93, 160408, 2004], MS inconsisten...
Different Adiabatic Quantum Optimization Algorithms for the NP-Complete Exact Cover and 3SAT Problems
Different Adiabatic Quantum Optimization Algorithms the NP-Complete Exact Cover 3SAT Problems

2010/10/29
One of the most important questions in studying quantum computation is: whether a quantum computer can solve NP-complete problems more efficiently than a classical computer? In 2000, adiabatic quantu...
