One-spin quantum logic gates from exchange interactions and a global magnetic field
Lian-Ao Wu, Daniel A. Lidar, Mark Friesen
It has been widely assumed that one-qubit gates in spin-based quantum computers suffer from severe technical difficulties. We show that one-qubit gates can in fact be generated usi…
On the Quantum Computational Complexity of the Ising Spin Glass Partition Function and of Knot Invariants
Daniel A. Lidar
It is shown that the canonical problem of classical statistical thermodynamics, the computation of the partition function, is in the case of +/-J Ising spin glasses a particular in…
Entangling capacities of noisy two-qubit Hamiltonians
Somshubhro Bandyopadhyay, Daniel A. Lidar
We show that intrinsic fluctuations in system control parameters impose limits on the ability of two-qubit (exchange) Hamiltonians to generate entanglement starting from mixed init…
Overcoming Quantum Noise in Optical Fibers
Lian-Ao Wu, Daniel A. Lidar
Noise in optical Telecom fibers is an important limitation on optical quantum data transmission. Unfortunately, the classically successful amplifiers (such as EDFA) cannot be used…
A Magnetic Resonance Realization of Decoherence-Free Quantum Computation
Jason E. Ollerenshaw, Daniel A. Lidar, Lewis E. Kay
We report the realization, using nuclear magnetic resonance techniques, of the first quantum computer that reliably executes an algorithm in the presence of strong decoherence. The…
