Ensemble quantum computing by NMR spectroscopy.
A quantum computer (QC) can operate in parallel on all its possible inputs at once, but the amount of information that can be extracted from the result is limited by the phenomenon of wave function collapse. We present a new computational model, which differs from a QC only in that the result of a measurement is the expectation value of the observable, rather than a random eigenvalue thereof. S...
متن کاملEnsemble Quantum Computing by Nuclear Magnetic Resonance Spectroscopy
A quantum computer is a machine which can operate in parallel on all its possible inputs at once, and can be programmed much like a conventional digital computer. It is based on the fact that the number of degrees of freedom in a collection of coupled two-state quantum systems grows exponentially with the number of systems. A major problem with quantum computers is that the amount of informatio...
متن کاملNMR Quantum Computing
The goal of this project is to do ‘proof of concept’ quantum information processing. The basic elements needed for this are a quantum system and a way to control and measure its state. Our quantum system is a solution of C-13 Chloroform, and we interacted with system’s state using Cornell College’s Nuclear Magnetic Resonance (NMR) spectrometer. By mapping certain aspects of the quantum state to...
متن کاملNMR Quantum Computing
Quantum computing is at the forefront of the scientific and technological research and development of the 21 century. NMR quantum computing is one the most mature technologies for implementing quantum computation. It utilizes the motion of spins of nuclei in custom-designed molecules manipulated by RF pulses. The motion is on a nanoor microscopic scale governed by the Schrödinger equation in qu...
متن کاملUltrafast double-quantum NMR spectroscopy.
We demonstrate the acquisition of double-quantum NMR spectra in less than three seconds and illustrate the synergies between double-quantum and ultrafast NMR spectroscopy for the analysis of complex mixtures.
