Loss Tolerant Linear Optical Quantum Memory By Measurement Based Quantum Computing

چکیده
We give a scheme for loss tolerantly building a linear optical quantum memory which itself is tolerant to qubit loss. We use the encoding recently introduced in [1] and give a method for efficiently achieving this. The entire approach resides within the “one-way” model for quantum computing [2]. Our results suggest that it is possible to build a loss tolerant quantum memory, such that if the requirement is to keep the data stored over arbitrarily long times then this is possible with only polynomially increasing resources and logarithmically increasing individual photon lifetimes.

Quantum logic gates can be built using linear optics, photon detection and ancillary resources in a scalable manner, as shown by Knill, Laflamme and Milburn (KLM) [1]. A number of experimental efforts are currently focused on testing the building blocks of linear optical quantum computing (LOQC) [2, 3, 4]. However, optimism for large scale quantum computation based on LOQC has been tempered by ...
متن کاملFault-tolerant linear optics quantum computation by error-detecting quantum state transfer
A scheme for linear optical implementation of fault-tolerant quantum computation is proposed, which is based on an error-detecting code. Each computational step is mediated by transfer of quantum information into an ancilla system embedding error-detection capability. Photons are assumed to be subjected to both photon loss and depolarization, and the threshold region of their strengths for scal...
متن کاملFault tolerant quantum key distribution protocol with collective random unitary noise
We propose an easy implementable prepare-and-measure protocol for robust quantum key distribution with photon polarization. The protocol is fault tolerant against collective random unitary channel noise. The protocol does not need any collective quantum measurement or quantum memory. A security proof and a specific linear optical realization using spontaneous parametric down conversion are given.
متن کاملLoss-tolerant optical qubits.
We present a linear optics quantum computation scheme that employs a new encoding approach that incrementally adds qubits and is tolerant to photon loss errors. The scheme employs a circuit model but uses techniques from cluster-state computation and achieves comparable resource usage. To illustrate our techniques we describe a quantum memory which is fault tolerant to photon loss.
متن کاملGain optimization of the optical waveguide based on the quantum box core/shell structure
In order to implement an integrated optical quantum circuit, designing waveguides based on the quantum box is of prime importance. To do this we have investigated optical waveguide both with and without optical pumping. The rate of absorption and emission using an array of AlGaAs/GaAs quantum box core/shell structure in the optical waveguide with various pumping intensities has computed. By con...
