Fault 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.

Quantum Public-Key Cryptosystem Based on Super Dense Coding Technology

In this paper we provide a quantum public-key cryptosystem based on super dense coding technology. A user Alice shares a set of Einstein-Podolsky-Rosen (EPR) pairs with a key management center (KMC) in which the particles hold by Alice are the private key and the particle hold by KMC are the public key. By the help of the key management center any other user can send encrypted message to Alice....

Fault-tolerant adder design in quantum-dot cellular automata

Quantum-dot cellular automata (QCA) are an emerging technology and a possible alternative for faster speed, smaller size, and low power consumption than semiconductor transistor based technologies. Previously, adder designs based on conventional designs were examined for implementation with QCA technology. This paper utilizes the QCA characteristics to design a fault-tolerant adder that is more...

Fault-tolerant quantum computation against biased noise

We formulate a scheme for fault-tolerant quantum computation that works effectively against highly biased noise, where dephasing is far stronger than all other types of noise. In our scheme, the fundamental operations performed by the quantum computer are single-qubit preparations, single-qubit measurements, and conditionalphase CPHASE gates, where the noise in the CPHASE gates is biased. We sh...

Fault-tolerant quantum computation versus Gaussian noise

The theory of fault-tolerant quantum computation shows that properly encoded quantum information can be protected against decoherence and processed reliably with imperfect hardware 1 . Demonstrating that this theory really works in practice is one of the great challenges facing contemporary science. A large-scale fault-tolerant quantum computer would be a scientific milestone, and it should als...
