“…Specifically, this option swaps amplitudes of |01⟩ and |11⟩ in the input vector [32], where the relation between both versions of Figure 1 is CX b) = (H ⨂ (h) CX a) (H ⨂ (h), being "⨂" is the Kronecker product [27,30,31]. Then, incorporating the option selected above, if we multiply F 2 2 by itself, and we do the same with F 2−1 2 2 , Equation (7) shows that both multiplications result identical and also equal to the CNOT gate of Figure 1b [27],…”

“…In the last two decades, QFT has participated in the most diverse studies, such as the analysis of spectral effects in quantum teleportation [4], its experimental implementation using the local classical entanglement state between the polarization and orbital angular momentum [5], the relation between spectral theory and quantum mechanics [6], the teleportation of multiple qubits based on QFT [7,8] where this tool is used to find orthogonal bases on which the sender projects the states to be teleported, the explanation about the surprising result that the Groverian entanglement of the periodic states built up during the preprocessing stage is only slightly affected by the QFT [9], its implementation in an entangled system of multilevel atoms [10], the realization of the two-qubit QFT and entangled protected using a Hamiltonian, which constitutes a matrix with circulant symmetry [11], its use in multiparty quantum telecommunication [12], its use as a tool to investigate phenomena such as quantum symmetry [13], and in an interesting study that showed herein that under the constraints imposed by quantum decoherence [14], only a parallel approach of QFT can guarantee a reliable solution or, alternatively, improve scalability [15] of this important tool.…”

This study establishes, for the first time in literature, that quantum entanglement, as well as the most important protocol derived from it, that is, quantum teleportation, completely rest on the Quantum Fourier Transform. This highlights the spectral nature of both protocols with important consequences on quantum computing, quantum communications, and quantum cryptography, with a particular emphasis on quantum Internet.

“…Quantum communication, an indispensable branch of quantum information, mainly involves quantum teleportation [1][2][3][4][5], quantum dense coding [6][7][8], quantum secret sharing [9][10][11] and quantum key distribution [12][13][14]. Quantum communication, leveraging the intrinsic characteristics of quantum mechanics, offers a significantly higher level of security than classical communication [15].…”

Quantum teleportation as the key strategy for quantum communication requires pure maximally shared entangled states among quantum nodes. In practice, quantum decoherence drastically degrades the shared entanglement during entanglement distribution, which is a serious challenge for the development of quantum networks. However, most of the decoherence control strategies proposed thus far are either resource-intensive or time-consuming. To overcome this obstacle, we enable noise-resistant teleportation through noisy channel with a limited number of qubits and without applying time-consuming weak measurements. We apply a quantum gate control unit consisting of a CNOT and a rotation gate after the original teleportation protocol is accomplished. Furthermore, we demonstrate that the teleportation fidelity of unity is attainable when environment-assisted measurement is added to the proposed teleportation protocol via quantum gates. Moreover, we present an entanglement distribution process by employing the designed quantum gate control unit followed by the deterministic standard teleportation protocol to improve the teleportation fidelity from the perspective of establishing improved shared entanglement. Our performance analysis indicates that the proposed teleportation schemes offer a competitive fidelity and success probability compared to the conventional and a recent weak measurement-based teleportation protocol.

Orthogonal frequency-division multiplexing (OFDM) is a crucial modulation method used in contemporary digital communication systems for its significant spectral efficiency, low latency, and robustness in challenging environments. This work examines the novel use of OFDM in quantum communication, an area that offers exceptional security and efficiency in information transfer using quantum mechanics principles. In the rapidly evolving field of quantum computing, understanding, and mitigating quantum bit errors is paramount. This paper presents a rigorous analysis of bit error rates (BER) in quantum circuits, focusing on the impact of the quantum Fourier transform and its inverse, contrasted against quantum circuits employing dynamic gate sequences. Our research methodology encompasses simulations over a diverse set of parameters, including varying qubit counts ranging from 2 to 8 and theta angles (15, 30, 45, and 60°), as well as random theta values, utilizing the advanced capabilities of the Qiskit framework. Our findings indicate that quantum OFDM substantially improves quantum communication, lowering errors and boosting security. The quantum model outperforms the reference model in BER, with further enhancements as qubits increase.
