Maximal success probabilities of linear-optical quantum gates
Numerical optimization is used to design linear-optical devices that implement a desired quantum gate with perfect fidelity, while maximizing the success rate. For the two-qubit controlled-sign or controlled NOT CNOT gate, we provide numerical evidence that the maximum success rate is S=2 /27 using two unentangled ancilla resources; interestingly, additional ancilla resources do not increase th...
متن کاملProposed Experiment in Two-qubit Linear Optical Photonic Gates for Maximal Success Rates
Here we propose an experiment in linear optical quantum computing (LOQC) using the framework first developed by Knill, Laflamme and Milburn. This experiment will test the ideas of the authors’ previous work on imperfect LOQC gates using number-resolving photon detectors. We suggest a relatively simple physical apparatus capable of producing CZ gates with controllable fidelity less than 1 and su...
متن کاملQuantum Logic Gates in Optical Lattices
We propose a new system for implementing quantum logic gates: neutral atoms trapped in a very far-off-resonance optical lattice. Pairs of atoms are made to occupy the same well by varying the polarization of the trapping lasers, and then a near-resonant electric dipole is induced by an auxiliary laser. A controlled-NOT can be implemented by conditioning the target atomic resonance on a resolvab...
متن کاملImplementing quantum gates on oriented optical isomers.
Optical enantiomers are proposed to encode molecular two-qubit information processing. Using sequences of pairs of nonresonant optimally polarized pulses, different schemes to implement quantum gates, and to prepare entangled states, are described. We discuss the role of the entanglement phase and the robustness of the pulse sequences which depend on the area theorem. Finally, possible scenario...
متن کاملQuantum matchgate computations and linear threshold gates
The theory of matchgates is of interest in various areas in physics and computer science. Matchgates occur, for example, in the study of fermions and spin chains, in the theory of holographic algorithms and in several recent works in quantum computation. In this paper, we completely characterize the class of Boolean functions computable by unitary two-qubit matchgate circuits with some probabil...
