Spin systems such as silicon and nitrogen-vacancy centers in diamond, quantum dots, and
quantum dot molecules coupled to optical cavities appear to be key elements for creating …

Preparing large-scale multi-partite entangled states of quantum bits in each physical form
such as photons, atoms or electrons for each specific application area is a fundamental …

We identify a novel qudit gate which we refer to as the gate. This is an alternate
generalization of the qutrit T gate to any odd prime dimension d, in the dth level of the …

We investigate two quantum communication protocols of dense coding and teleportation
based on two coupled quantum dot molecules under intrinsic decoherence, tunneling rates …

In large quantum systems, multipartite entanglement can be found in many inequivalent
classes. Preparing states of arbitrary size in different classes is important for performing a …

A novel quantum teleportation protocol for certain class of eight-qubit state is proposed. We
utilize a six-qubit cluster state as quantum channel. In our scheme, the sender performs four …

Fusion technique plays a key role in the preparation of large-scale W states, but the currently
existing fusion schemes are suffering from the qubit loss problem, ie, the number of the …

In this paper, we demonstrate that two Greenberger-Horne-Zeilinger (GHZ) states can be
used to realize the perfect and deterministic controlled remote state preparation of an …

We propose three schemes to generate polarization W-states of size n+ m, n+ m+ t, and n+
m+ t+ z without qubit loss, ie, large-sized W n+ m (W n+ m+ t and W n+ m+ t+ z) is generated …

Having access to ideal quantum mechanical resources, the prisoners' dilemma can be
ceased. Here, we propose a distributed quantum circuit to allow spatially separated …
