Quantum Information Systems: Using a Two-Spin System and Nuclear Magnetic Resonance
نویسندگان
چکیده
Information systems are an essential part of everyday life. Standard computers rely on the detection of charge to process information; quantum computers use quantum states to represent information[15]. There are a few different techniques that can be used to complete quantum computations, including iontrap[3], quantum dots[1], and nuclear magnetic resonance (NMR) experiments. In the case of our work, we employed a commercially available Nuclear Magnetic Resonance device and a chemical system of isotopicially enriched Carbon-13 chloroform.

Experimental Simulation of Spin Squeezing by Nuclear Magnetic Resonance
We report on the experimental simulation of spin squeezing using a liquid-state nuclear magnetic resonance (NMR) quantum information processor. This was done by identifying the energy levels within the symmetric subspace of a system of n spin-1/2 nuclei with the energy levels of the simulated spin-(n/2) system. The results obtained for our simulations of spin-1 and spin-3/2 systems are consiste...
متن کاملConfluence of resonant laser excitation and bidirectional quantum-dot nuclear-spin polarization
Resonant laser scattering along with photon correlation measurements established the atom-like character of quantum dots. Here, we show that for a wide range of experimental parameters it is impossible to isolate elementary quantum-dot excitations from a strong influence of nuclear spins; the absorption lineshapes at magnetic fields exceeding 1 T indicate that the nuclear spins get polarized by...
متن کاملQuantum information processing by nuclear magnetic resonance on quadrupolar nuclei.
Nuclear magnetic resonance is viewed as an important technique for the implementation of many quantum information algorithms and protocols. Although the most straightforward approach is to use the two-level system composed of spin 1/2 nuclei as qubits, quadrupolar nuclei, which possess a spin greater than 1/2, are being used as an alternative. In this study, we show some unique features of quad...
متن کاملNMR Implementation of a Building Block for Scalable Quantum Computation
We report the implementation of the central building block of the Schulman-Vazirani procedure for fully polarizing a subset of two-level quantum systems which are initially only partially polarized. This procedure consists of a sequence of unitary operations and incurs only a quasi-linear overhead in the number of quantum systems and operations required. The key building block involves three qu...
