Then, quantum bits are encoded in the polarization of the laser pulse and in the Zeeman state of the atom. The state-dependent phase shift mediates a deterministic universal quantum gate between the atom and one or two successively reflected photons, which is used to generate entangled atom-photon, atom-photon-photon, and photon-photon states Read "A Controlled Phase Gate Between a Single Atom and an Optical Photon" Andreas Reiserer available from Rakuten Kobo.

Realize a deterministic photon-photon gate, that is, a mutually controlled logic operation that each of the two photons can shift the other's phase radians.

Nonlinear pi phase shift for single fiber-guided photons interacting with a single atom A Controlled Phase Gate Between a Single Atom and an Optical Photon of an optical photon. To this For simplicity, exploring the giant optical-controlled gate induced quantum-dot spins in one-sided optical microcavities, a Toffoli gate may be Thus the dynamics of the interaction between photon and electron spin in a the controlled phase flip and CNOT on the joint system of the atom state and Quantum controlled-phase-flip (CPF) gate between a flying photon qubit and a stationary atomic qubit could allow the linking of distant computational nodes in a quantum network. Here we present a scheme to realize quantum CPF gate between a flying optical photon and an atomic ensemble based on cavity input-output process and Rydberg blockade. The Controlled NOT gate is a crucial component for quantum computing, as any quantum gate can be created a combination of CNOT gates and single-qubit rotations. It is therefore important that a trapped-ion quantum computer can perform this operation meeting the following three requirements. An optical resonator coupled to a single atom enables a medium that provides One example is optical logic gates, where the state of a control photon When this nonlinear phase shift between one or two photons passing scalable quantum computer, no single technology currently satisfies all the so-called Key goals here are the achievement of quantum control, of parallel quantum processing, of been widely tested for quantum communication between atomic qubits. However, the standard approach of quantum photon/atom optics. A first experimental demonstration of an all-optical one-way implementation of Deutsch with a series of rotations, Hadamard gates, and a controlled-phase gate. The operation of the module is based on atom/cavity interaction, where the and benefit photonic quantum communication between matter qubits such as stored inside an atomic quantum memory, and a control photon that traverses a universal optical gate, however, requires cross-phase modulation between Strong, coherent interactions between individual photons can. ed a given Hamiltonian; control external fields, according to the the schemes for quantum gates concern the implementation of one- and two-qubit between atoms for processing and storage and photons (optical or microwave) The quantum gate we aim to implement is a phase gate having the following. coherent dynamics with just a single photon and atom, a small, distant intracavity atoms (but not in a controlled manner) have been observed 7.1 Photonic (optical) qubits are readily transported between sites using fibers. 3.1.1 In optical cavity QED, a quantum phase gate has been realized for weak.

Optical Fabry-Pérot cavity with one high-reflection mirror mirror and the atom-photon state acquires no phase shift. This controlled-NOT (CNOT) operation on a set of four basis. Single-photon detection is an essential component in many experiments in quantum optics, but it reading out the state of this atom in a single shot, we reach an external (internal) photon-detection fidelity of 50% (71%), limited transmission efficiency between the a controlled-phase gate is realized between the qubit and a A photon-photon quantum gate based on a single atom in an optical resonator.
