Robot Programming Based on a Single Demon - Stration and User

This paper presents a method that allows to create programs by following the Programming by Demonstration paradigm. Plans for the execution of production processes such as assembly or stacking operation sequences are constructed not only from examples provided by the user through demonstrations. Additionally, the intention the user had in mind when demonstrating a speciic example is acquired th...

Oblivious transfer based on single-qubit rotations

We present a bit-string quantum oblivious transfer protocol based on single-qubit rotations. The proposed protocol does not violate the Lo’s nogo theorem that prevents the unconditional security of 1-out-of-2 oblivious transfer. Our protocol is based on a previously proposed quantum public key protocol and its security relies on the laws of Quantum Mechanics. We also present a single-bit oblivi...

Precision of single-qubit gates based on Raman transitions

We analyze the achievable precision for single-qubit gates that are based on Raman transitions between two near-degenerate ground states via a virtually excited state. In particular, we study the errors due to non-perfect adiabaticity and due to spontaneous emission from the excited state. For the case of non-adabaticity, we calculate the error as a function of the dimensionless parameter χ = ∆...

Isolating a Single Qubit in a Multi Qubit System

Quantum computing, a whole new paradigm to computing, is based on using Quantum Mechanics for computation. The basic element in a quantum computer is a “qubit” which is a two-state physical system. Unlike a classical bit which can exist in one of two states, 0 or 1, a qubit can not only exist in its two basis states, but also in any linear combination of these states. A quantum computer compris...

Controlling qubit arrays with anisotropic XXZ Heisenberg interaction by acting on a single qubit

We investigate anisotropic XXZ Heisenberg spin-1/2 chains with control fields acting on one of the end spins, with the aim of exploring local quantum control in arrays of interacting qubits. In this work, which uses a recent Lie-algebraic result on the local controllability of spin chains with “alwayson” interactions, we determine piecewise-constant control pulses corresponding to optimal fidel...
