Abstract

Abstract The possibility of implementing a controlled-NOT gate for frequency-encoded photonic qubits via six-wave mixing in a multilevel atomic system is shown. Starting from the Hamiltonian for six-wave mixing in a cavity, equations of motion for the amplitudes of the photonic states are derived and solved in the framework of input–output formalism. Analysis of these solutions show how to realize two-qubit gates including relevant matching conditions.

A Quantum-Controlled NOT Gate Based on Four-Wave Mixing in a Cavity for Polarization Photonic Qubits

S. N. Andrianov, А. А. Калачев, O. P. Shindyaev +1 more

Abstract The possibility of effectively creating quantum gates based on polarization photon qubits using a Kerr nonlinear medium in a cavity is studied. It is shown how a quantum C-NOT gate can be produced with such qubits through four-wave mixing. A theory of this gate’s operation is constructed using an input–output formalism, and conditions of parametric matching are obtained for effective gate operation.

A Quantum Control NOT Gate Based on Four-Wave Mixing in a Cavity for Photonic Qubits with Orbital Angular Momentum

Abstract Photonic qubits with angular momentum states interacting in a medium with Kerr-type nonlinearity in a cavity are considered. The use of a quantum logic gate (a controlled NOT gate) in the process of four-wave mixing on such qubits is considered. A theory of the functioning of this gate is constructed using the input/output formalism. The conditions for matching the parameters that must be realized for the effective operation of the gate are obtained.

Multi-qubit controlled NOT gates for artificial intelligence natural languages processing

Natural language processing is efficient using quantum neural networks including multiqubit controlled NOT gates with multiple control qubits and a single target qubit. We propose here a photonic miltiqubit controlled NOT gate based on a multi-wave mixing process in a cavity. Theory of such a multiqubit gate is constructed using input-output formalism. Parameters matching condition is found that must be fulfilled for successful gate operation. Recommendations are given for the construction of quantum neural networks that are able to solve various practical problems of natural language processing.

A Two-Qubit Controlled-NOT Gate for Multi-Color Quantum Photonic Systems

Hiva Shahoei, Duncan L. MacFarlane, Mitchell Aaron Thornton

We present a conceptual KLM-style implementation of a two-qubit controlled-NOT (CNOT) gate for frequency-encoded (multi-color) photonic qubits. The CNOT operation is constructed through an$\mathrm{H}-\text{CZ}-\mathrm{H}$decomposition, where programmable frequency-domain Hadamard transformations are implemented using a parallel frequency-mixing architecture. This parallel configuration enables controlled redistribution of probability amplitudes among frequency bins while maintaining scalability and reduced parasitic loss compared to serial architectures. The nonlinearity required for the CZ gate is realized through two-photon interference at a partial beam splitter within an otherwise linear optical system, without requiring auxiliary photons. This approach provides a resource-efficient and scalable framework for frequency-domain quantum logic and multi-color photonic quantum information processing.

A controlled-NOT gate for frequency-bin qubits

Hsuan‐Hao Lu, Joseph M. Lukens, Brian P. Williams +4 more

Abstract The realization of strong photon–photon interactions has presented an enduring challenge across photonics, particularly in quantum computing, where two-photon gates form essential components for scalable quantum information processing (QIP). While linear-optic schemes have enabled probabilistic entangling gates in spatio-polarization encoding, solutions for many other useful degrees of freedom remain missing. In particular, no two-photon gate for the important platform of frequency encoding has been experimentally demonstrated, due in large part to the additional challenges imparted by the mismatched wavelengths of the interacting photons. In this article, we design and implement an entangling gate for frequency-bin qubits, a coincidence-basis controlled-NOT (CNOT), using line-by-line pulse shaping and electro-optic modulation. We extract a quantum unitary fidelity of 0.91 ± 0.01 via a parameter inference approach based on Bayesian machine learning, which enables accurate gate reconstruction from measurements in the two-photon computational basis alone. Our CNOT imparts a single-photon frequency shift controlled by the frequency of another photon—an important capability in itself—and should enable new directions in fiber-compatible QIP.
