Energy-constrained LOCC-assisted quantum capacity of bosonic dephasing channel
Amir Arqand, Laleh Memarzadeh, Stefano Mancini
We study the LOCC-assisted quantum capacity of bosonic dephasing channel with energy constraint on input states. We start our analysis by focusing on the energy-constrained squashe…
Correlation-Enabled Energy Exchange in Quantum Systems without External Driving
T. Pyhäranta, S. Alipour, A. T. Rezakhani +1
We study the role of correlation in mechanisms of energy exchange between an interacting bipartite quantum system and its environment by decomposing the energy of the system to loc…
Estimating energy levels of a three-level atom in single and multi-parameter metrological schemes
Hossein Rangani Jahromi, Roya Radgohar, Seyed Mohammad Hosseiny +1
Determining the energy levels of a quantum system is a significant task, for instance, to analyze reaction rates in drug discovery and catalysis or characterize the compatibility o…
Geometric Bloch Vector Solution to Minimum Error Discriminations of Mixed Qubit States
Mahdi Rouhbakhsh N., Seyed Arash Ghoreishi
We investigate minimum-error (ME) discrimination for mixed qubit states using a geometric approach. By analyzing positive operator-valued measure (POVM) solutions and introducing L…
Quantum noise can enhance algorithmic cooling
Zahra Farahmand, Reyhaneh Aghaei Saem, Sadegh Raeisi
Heat-Bath Algorithmic Cooling techniques (HBAC) are techniques that are used to purify a target element in a quantum system. These methods compress and transfer entropy away from t…
Quantum CDMA Communication Systems
Mohammad Rezai, Jawad A. Salehi
Barcoding photons can provide a host of functionalities that could benefit future quantum communication systems and networks beyond today's imagination. As a significant applicatio…
