Abstract

We experimentally demonstrate an all-optical quantum gate that, with high fidelity, reproduces the entanglement and truth table of a controlled-NOT. We completely characterize it using quantum process tomography, obtaining an average process fidelity of 0.81.

Quantum Process Tomography of a Controlled-NOT Gate

Jeremy L. O’Brien, Geoff J. Pryde, Alexei Gilchrist +4 more

We demonstrate complete characterization of a two-qubit entangling process--a linear optics controlled-NOT gate operating with coincident detection--by quantum process tomography. We use a maximum-likelihood estimation to convert the experimental data into a physical process matrix. The process matrix allows an accurate prediction of the operation of the gate for arbitrary input states and a calculation of gate performance measures such as the average gate fidelity, average purity, and entangling capability of our gate, which are 0.90, 0.83, and 0.73, respectively.

Demonstration of an Optical Quantum Controlled-NOT Gate without Path Interference

Ryo Okamoto, Holger Friedrich Hofmann, Shigeki Takeuchi +1 more

We report the first experimental demonstration of an optical quantum controlled-NOT gate without any path interference, where the two interacting path interferometers of the original proposals have been replaced by three partially polarizing beam splitters with suitable polarization dependent transmittance and reflectance. The performance of the device is evaluated using a recently proposed method, by which the quantum process fidelity and the entanglement capability can be estimated from the 32 measurement results of two classical truth tables, significantly less than the 256 measurement results required for full quantum tomography.

Optical Nondestructive Controlled-NOT Gate without Using Entangled Photons

Xiao‐Hui Bao, Teng‐Yun Chen, Qiang Zhang +4 more

We present and experimentally demonstrate a novel optical nondestructive controlled-NOT gate without using entangled ancilla. With much fewer measurements compared with quantum process tomography, we get a good estimation of the gate fidelity. The result shows a great improvement compared with previous experiments. Moreover, we also show that quantum parallelism is achieved in our gate and the performance of the gate cannot be reproduced by local operations and classical communications.

Experimental Teleportation of a Quantum Controlled-NOT Gate

Yun‐Feng Huang, Xi‐Feng Ren, Yong-Sheng Zhang +2 more

Teleportation of quantum gates is a critical step for the implementation of quantum networking and teleportation-based models of quantum computation. We report an experimental demonstration of teleportation of the prototypical quantum controlled-NOT (CNOT) gate. Assisted with linear optical manipulations, photon entanglement produced from parametric down-conversion, and postselection from the coincidence measurements, we teleport the quantum CNOT gate from acting on local qubits to acting on remote qubits. The quality of the quantum gate teleportation is characterized through the method of quantum process tomography, with an average fidelity of 0.84 demonstrated for the teleported gate.

Demonstration of a Neutral Atom Controlled-NOT Quantum Gate

L. Isenhower, Erik Urban, X. L. Zhang +5 more

We present the first demonstration of a CNOT gate between two individually addressed neutral atoms. Our implementation of the CNOT uses Rydberg blockade interactions between neutral atoms held in optical traps separated by >8 microm. Using two different gate protocols we measure CNOT fidelities of F=0.73 and 0.72 based on truth table probabilities. The gate was used to generate Bell states with fidelity F=0.48+/-0.06. After correcting for atom loss we obtain an a posteriori entanglement fidelity of F=0.58.
