Effects of noise on quantum error correction algorithms
Adriano Barenco, Todd A. Brun, Ruediger Schack +1
It has recently been shown that there are efficient algorithms for quantum computers to solve certain problems, such as prime factorization, which are intractable to date on classi…
Quantum Physics and Computers
Adriano Barenco
Recent theoretical results confirm that quantum theory provides the possibility of new ways of performing efficient calculations. The most striking example is the factoring problem…
Stabilisation of Quantum Computations by Symmetrisation
Adriano Barenco, Andre` Berthiaume, David Deutsch +3
We propose a method for the stabilisation of quantum computations (including quantum state storage). The method is based on the operation of projection into , the symmetr…
Approximate Quantum Fourier Transform and Decoherence
Adriano Barenco, Artur Ekert, Kalle-Antti Suominen +1
We discuss the advantages of using the approximate quantum Fourier transform (AQFT) in algorithms which involve periodicity estimations. We analyse quantum networks performing AQFT…
Quantum Networks for Elementary Arithmetic Operations
V. Vedral, A. Barenco, A. Ekert
Quantum computers require quantum arithmetic. We provide an explicit construction of quantum networks effecting basic arithmetic operations: from addition to modular exponentiation…
Universality in Quantum Computation
D. Deutsch, A. Barenco, A. Ekert
We show that in quantum computation almost every gate that operates on two or more bits is a universal gate. We discuss various physical considerations bearing on the proper defini…
