The Singapore University of Technology and Design is Singapore's fourth autonomous university, developed in collaboration with Massachusetts Institute of Technology. SUTD's mission is to advance knowledge and nurture technically grounded leaders and innovators to serve societal needs. At SUTD, design as a discipline cuts across the curriculum and provides a novel framework for the research and educational programmes.The University, also in collaboration with Zhejiang University is distinguished by its unique East and West academic programme which incorporates elements of technology, entrepreneurship, management and design thinking. MIT faculty has played a significant role in developing a blueprint for the curriculum, including its structure and the degrees to be offered. SUTD undergraduate students are granted either a Bachelor of Engineering or a Bachelor of Science degrees with a major in either Architecture and Sustainable Design , Engineering Product Development , Engineering Systems Design or Informations Systems and Technology Design . It also offers an MIT-SUTD Dual Masters' Degree Programme; a full-time programme leading to a degree from both MIT and SUTD. SUTD also offers Ph.D in each of its four areas of focus .Unlike traditional schools where students focus on very specialized disciplines, SUTD students are taught to think in a broader scope combining multiple domains. It teaches its students to be creative, not just in the technology and design part, but also to be creative in bringing ideas out of the academic environment into the real world, into the business arena, into the economy and make a difference to the world. SUTD is the only other institution in Singapore apart from Yale-NUS College to follow a holistic admissions process. Wikipedia.

Quantum computers are expected to offer substantial speed-ups over their classical counterparts and to solve problems intractable for classical computers. Beyond such practical significance, the concept of quantum computation opens up fundamental questions, among them the issue of whether quantum computations can be certified by entities that are inherently unable to compute the results themselves. Here we present the first experimental verification of quantum computation. We show, in theory and experiment, how a verifier with minimal quantum resources can test a significantly more powerful quantum computer. The new verification protocol introduced here uses the framework of blind quantum computing and is independent of the experimental quantum-computation platform used. In our scheme, the verifier is required only to generate single qubits and transmit them to the quantum computer. We experimentally demonstrate this protocol using four photonic qubits and show how the verifier can test the computer's ability to perform quantum computation. © 2013 Macmillan Publishers Limited.

Inhomogeneity, in its many forms, appears frequently in practical physical systems. Readily apparent in quantum systems, inhomogeneity is caused by hardware imperfections, measurement inaccuracies, and environmental variations, and subsequently limits the performance and efficiency achievable in current experiments. In this paper, we provide a systematic methodology to mathematically characterize and optimally manipulate inhomogeneous ensembles with concepts taken from ensemble control. In particular, we develop a computational method to solve practical quantum pulse design problems cast as optimal ensemble control problems, based on multidimensional pseudospectral approximations. We motivate the utility of this method by designing pulses for both standard and novel applications. We also show the convergence of the pseudospectral method for optimal ensemble control. The concepts developed here are applicable beyond quantum control, such as to neuron systems, and furthermore to systems with by parameter uncertainty, which pervade all areas of science and engineering. © 2012 IEEE.

In this work, we introduce the concept of Dynamic Switch-based Forwarding (DSF) that optimizes the 1) expected data delivery ratio, 2) expected communication delay, or 3) expected energy consumption for low-duty-cycle wireless sensor networks under unreliable communication links. DSF is designed for networks with possibly unreliable communication links and predetermined node communication schedules. To our knowledge, these are the most encouraging results to date in this new research direction. In this paper, DSF is evaluated with a theoretical analysis, extensive simulation, and physical testbed consisting of 20 MicaZ motes. Results reveal the remarkable advantage of DSF in extremely low-duty-cycle sensor networks in comparison to three well-known solutions (ETX [CHECK END OF SENTENCE], {\rm PRR}\times{\rm D} [CHECK END OF SENTENCE], and DESS [CHECK END OF SENTENCE]). We also demonstrate our solution defaults into ETX in always-awake networks and DESS in perfect-link networks. © 2006 IEEE. Source

Mono-layer graphene integrated with optical waveguides is studied for the purpose of maximizing E-field interaction with the graphene layer, for the generation of ultra-large nonlinear parameters. It is shown that the common approach used to minimize the waveguide effective modal area does not accurately predict the configuration with the maximum nonlinear parameter. Both photonic and plasmonic waveguide configurations and graphene integration techniques realizable with today's fabrication tools are studied. Importantly, nonlinear parameters exceeding 104W-1/m, two orders of magnitude larger than that in silicon on insulator waveguides without graphene, are obtained for the quasi-TE mode in silicon waveguides incorporating mono-layer graphene in the evanescent part of the optical field. Dielectric loaded surface plasmon polariton waveguides incorporating mono-layer graphene are observed to generate nonlinear parameters as large as 105W-1/m, three orders of magnitude larger than that in silicon on insulator waveguides without graphene. The ultra-large nonlinear parameters make such waveguides promising platforms for nonlinear integrated optics at ultra-low powers, and for previously unobserved nonlinear optical effects to be studied in a waveguide platform. ©2014 Optical Society of America.

The effect of group velocity dispersion and free carrier lifetime on pulse quality and nonlinear phase acquisition is studied in a two-stage pulse compressor on a silicon chip. Appropriately, designing the dispersion in the nonlinear medium enables compressed pulses with more than 90 of the pulse energy confined in the main lobe to be generated. Free carrier lifetime is observed to impact nonlinear phase acquisition in the single pulse regime. The pulse compression factor decreases monotonically as the pulse repetition rate increases. Conditions for efficient compression at high repetition rates in the absence of free carrier quenching techniques are discussed. © 2012 American Institute of Physics. Source
