Implementation of Reversible Logic Gates with Quantum Gates

Computing and Communication Workshop and Conference, 2021
Quantum is an emerging technology in future computers. Reversibility is the main advantage of quantum computers. In conventional computers, the computation is irreversible i.e.

Implementation of Quantum Gates based Logic Circuits using IBM Qiskit

International Conference on Communication, Computing & Security, 2020
Quantum computing is an emerging field that depends upon the basic properties of quantum physics and principles of classical systems. This leads a way to develop systems to solve complex problems that a classical system cannot do.

QUANTUM DOT COMPUTING GATES

International Journal of Quantum Information, 2006
Semiconductor quantum dots are a promising candidate for future quantum computer devices. Presently, there are three major proposals for designing quantum computing gates based on quantum dot technology: (i) electrons trapped in microcavity; (ii) spintronics; (iii) biexcitons. We survey these designs and show mathematically how, in principle, they will

Quantum gates and degenerations

Journal of Physics A: Mathematical and General, 2004
Summary: A three state Hamiltonian with a degenerate ground state is shown to exhibit the property of generating quantum gates for fixed values of the energy parameters just by using the ability of this quantum system to evolve in time yielding suitable sets of quantum probabilities.

Programmable Quantum Gate Arrays

Fortschritte der Physik, 2001
Summary: We present a probabilistic quantum processor for qubits. The processor itself is represented by a fixed array of gates. The input of the processor is constituted by two registers. In the program register the set of instructions (program) is encoded. This program is applied to the data register.

Realizable Universal Quantum Logic Gates

Physical Review Letters, 1995
We identify a 2-bit quantum gate that is sufficient to build any quantum logic network. The existence of such a 2-bit universal gate considerably simplifies the search for physical realizations of quantum computational networks. We propose an explicit construction of this gate, which is based on cavity QED techniques and may be realizable with current ...

Gate-Controlled Atomic Quantum Switch

Physical Review Letters, 2004
An atomic-scale quantum conductance switch is demonstrated that allows us to open and close an electrical circuit by the controlled and reproducible reconfiguration of silver atoms within an atomic-scale junction. The only movable parts of the switch are the contacting atoms.

Quantum Gates and Quantum Circuits

2022
Abstract Quantum gates, equivalent to logic gates, operate on and modify the state vectors. Alice and Bob explain what quantum gates do and illustrate their action on states describing a single qubit. These gates include the NOT gate, the Pauli gates, and the Hadamard gate.
