We develop a theory for the interaction of multilevel atoms with multimode cavities yielding cavity-enhanced multiphoton resonances. The locations of the resonances are predicted from the use of effective two- and three-level Hamiltonians. As an application we show that quantum gates can be realized when photonic qubits are encoded on the cavity modes in arrangements where ancilla atoms transit the cavity. The fidelity of operations is increased by conditional measurements on the atom and by… Expand

Quantum phase gate based on multiphoton process in multimode cavity QED
TLDR
A scheme for implementing a two-qubit quantum phase gate in which the photonic qubits encoded on the cavity modes and a three-level V-type atom passes through the cavity, predicted from the use of the theory of multiphoton resonance is proposed. Expand
Multiphoton process in cavity QED photons for implementing a three-qubit quantum gate operation
TLDR
Based on cavity QED of free atoms, the implementation of a three-qubit quantum phase gate in which the three qubits are represented by the photons in modes of the cavity is theoretically investigated and the effects of deviation in detunings and coupling coefficients are addressed. Expand
Realization of the quantum CNOT gate based on multiphoton process in multimode Cavity QED
We propose a scheme for implementing the CNOT gate in which the photonic qubits encoded on the cavity modes and a four-level atom passes through the cavity. The location of the resonance is predictedExpand
Implementation of universal two- and three-qubit quantum gates in a cavity QED
We propose two schemes to directly implement the iSWAP and Fredkin gates by passing an atom across a multi-mode cavity QED. We have combined three types of qubits: the flying photonic qubits, theExpand

TLDR
I am writing with a simple plea to balance the voluminous articles about treatment in your journal with a modicum of information about nature and caring effects to rekindle the perception of physicians as healers, not only treaters, who relish the gifts of nature, and foster the humanistic aspect of medicine that has thrived for millennia.
