Paramagnetic Materials and Practical Algorithmic Cooling for Nmr Quantum Computing *
Algorithmic Cooling is a method that uses novel data compression techniques and simple quantum computing devices to improve NMR spectroscopy, and to offer scalable NMR quantum computers. The algorithm recursively employs two steps. A reversible entropy compression of the computation quantum-bits (qubits) of the system and an irreversible heat transfer from the system to the environment through ...
متن کاملAlgorithmic cooling and scalable NMR quantum computers.
We present here algorithmic cooling (via polarization heat bath)-a powerful method for obtaining a large number of highly polarized spins in liquid nuclear-spin systems at finite temperature. Given that spin-half states represent (quantum) bits, algorithmic cooling cleans dirty bits beyond the Shannon's bound on data compression, by using a set of rapidly thermal-relaxing bits. Such auxiliary b...

متن کاملAlgorithmic Cooling in Liquid State NMR
Algorithmic cooling is a method that employs thermalization to increase qubit purification level, namely it reduces the qubit-system’s entropy. We utilized gradient ascent pulse engineering (GRAPE), an optimal control algorithm, to implement algorithmic cooling in liquid state nuclear magnetic resonance. Various cooling algorithms were applied onto the three qubits of C2trichloroethylene, cooli...
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...
