Minimising the heat dissipation of quantum information erasure
M. Hamed Mohammady, Masoud Mohseni, Yasser Omar
Quantum state engineering and quantum computation rely on information erasure procedures that, up to some fidelity, prepare a quantum object in a pure state. Such processes occur w…
Transport of quantum excitations coupled to spatially extended nonlinear many-body systems
Stefano Iubini, Octavi Boada, Yasser Omar +1
The role of noise in the transport properties of quantum excitations is a topic of great importance in many fields, from organic semiconductors for technological applications to li…
Degradation of entanglement between two accelerated parties: Bell states under the Unruh effect
Benedikt Richter, Yasser Omar
We study the entanglement of families of Unruh modes in the Bell states and …
Measurement-Assisted Quantum Communication in Spin Channels with Dephasing
Abolfazl Bayat, Yasser Omar
We propose a protocol for countering the effects of dephasing in quantum state transfer over a noisy spin channel weakly coupled to the sender and receiver qubits. Our protocol, ba…
Systematic Dimensionality Reduction for Quantum Walks: Optimal Spatial Search and Transport on Non-Regular Graphs
Leonardo Novo, Shantanav Chakraborty, Masoud Mohseni +2
Continuous time quantum walks provide an important framework for designing new algorithms and modelling quantum transport and state transfer problems. Often, the graph representing…
Disorder-assisted quantum transport in suboptimal decoherence regimes
Leonardo Novo, Masoud Mohseni, Yasser Omar
We investigate quantum transport in binary tree structures and in hypercubes for the disordered Frenkel-exciton Hamiltonian under pure dephasing noise. We compute the energy transp…
Graphene Enabled Low-Control Quantum Gates between Static and Mobile Spins
G. Cordourier-Maruri, Y. Omar, R. de Coss +1
We show that the feature of Klein tunneling makes graphene a unique interface for implementing low control quantum gates between static and mobile qubits. A ballistic electron spin…
Geometrical effects on energy transfer in disordered open quantum systems
M. Mohseni, A. Shabani, S. Lloyd +2
We explore various design principles for efficient excitation energy transport in complex quantum systems. We investigate energy transfer efficiency in randomly disordered geometri…
Implementing quantum gates through scattering between a static and a flying qubit
G. Cordourier-Maruri, F. Ciccarello, Y. Omar +3
We investigate whether a two-qubit quantum gate can be implemented in a scattering process involving a flying and a static qubit. To this end, we focus on a paradigmatic setup made…
Entanglement Generation by a Three-Dimensional Qubit Scattering: Concurrence vs. Path (In)Distinguishability
Yuichiro Hida, Hiromichi Nakazato, Kazuya Yuasa +1
A scheme for generating an entangled state in a two spin-1/2 system by means of a spin-dependent potential scattering of another qubit is presented and analyzed in three dimensions…
