Seminar

This presentation will delve into a practical example of a patent procedure associated to a specific quantum technology: quantum random number generator. We will explore the specifics of the technology and its applications, review previously existing approaches and define the inventive step, explore the phrasing of the claims, and revisit the prior patents from the freedom-to-operate point of view.

Quantum coherence control in an inhomogeneously broadened lambda-type solid state ensemble has been studied for quantum memories over decades. Unlike akali atoms, the optically excited spin coherence in a rare-earth doped solid is sufferred from a serious spin dephasing problem due to spin inhomogeneity. Thus, solid state quantum memory protocols such as AFC and gradient echo have been effctively demonstrated only for optical transitions, whose coherence time is far shorter than ms.

In this presentation, physical properties and possible applications of carbon based nano electro-mechanical devices (NEMS) will be introduced. Our research started from carbon nanotube based nano electro-mechanical relay structure and expanded to graphene based xylophone and drum like devices. Micro contact transfer method is applied to realize the suspended nano structures with various electrodes under the nano materials.

Duality Quantum Computing: Computing with Linear Combinations of Unitaries

Gui-Lu Long, APS and IoP Fellow

Usually, a quantum algorithm uses products of unitaries to complete a task. Lack of technique and intuition in algorithm design has hindered the development of quantum algorithm.

A long-standing puzzle in quantum complexity theory is to understand the power of the class MIP* of multiprover interactive proofs with shared entanglement. This question is closely related to the study of entanglement through non-local games, which dates back to the pioneering work of Bell.

In 2011 Harry Buhrman, Serge Fehr, Christian Schaffner and Florian Speelman proposed a new measure of complexity for finite Boolean functions, called "The Garden-hose complexity". This measure can be viewed as a type of distributed space complexity where two players with private inputs compute a Boolean function co-operatively. While its motivation mainly came from the applications to position based quantum cryptography, the playful definition of the model is quite appealing in itself.

Recently, Silas Beane, David Kaplan, Natalie Klco and I considered the entanglement power of the S-­‐matrix describing low-­‐energy hadronic interactions, and the implications of particular limits. We found that vanishing entanglement power occurs at points of emergent global symmetries, which are seen to be consistent with nature and also recent lattice quantum chromodynamics (QCD) calculations. I will discuss aspects of these results.
