Bayesian Model of Dynamic Image Stabilization in the Visual System
(Proceedings of the National Academy of Sciences, 2010)Humans can resolve the fine details of visual stimuli although the image projected on the retina is constantly drifting relative to the photoreceptor array. Here we demonstrate that the brain must take this drift into ... -
Coherent Spin Manipulation in an Exchange-Only Qubit
(American Physical Society, 2010)Initialization, two-spin coherent manipulation, and readout of a three-spin qubit are demonstrated using a few-electron triple quantum dot. The three-spin qubit is designed to allow all operations for full qubit control ... -
Faster Quantum Chemistry Simulation on Fault-Tolerant Quantum Computers
(Institute of Physics, 2012)Quantum computers can in principle simulate quantum physics exponentially faster than their classical counterparts, but some technical hurdles remain. We propose methods which substantially improve the performance of a ... -
Finding long chains in kidney exchange using the traveling salesman problem
(Proceedings of the National Academy of Sciences, 2015)There are currently more than 100,000 patients on the waiting list in the United States for a kidney transplant from a deceased donor. To address this shortage, kidney exchange programs allow patients with living incompatible ... -
The mystery of language evolution
(Frontiers Media S.A., 2014)Understanding the evolution of language requires evidence regarding origins and processes that led to change. In the last 40 years, there has been an explosion of research on this problem as well as a sense that considerable ... -
Photonic Quantum Simulators
(Nature Publishing Group, 2012)Quantum simulators are controllable quantum systems that can be used to mimic other quantum systems. They have the potential to enable the tackling of problems that are intractable on conventional computers. The photonic ... -
Quantum Simulator of an Open Quantum System Using Superconducting Qubits: Exciton Transport in Photosynthetic Complexes
(Institute of Physics, 2012)Open quantum system approaches are widely used in the description of physical, chemical and biological systems. A famous example is electronic excitation transfer in the initial stage of photosynthesis, where harvested ... -
Scalable Architecture for a Room Temperature Solid-State Quantum Information Processor
(Nature Publishing Group, 2012)The realization of a scalable quantum information processor has emerged over the past decade as one of the central challenges at the interface of fundamental science and engineering. Here we propose and analyse an ...
