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.

“Quantum physics” has taken its position with “rocket science” in pop culture as a shorthand for frighteningly complicated science. Quantum physics has also taken on a sort of magical connotation in fiction, with features like entanglement, superposition, and tunneling, spurring imagination. But where does the science draw the line? How much is joyful speculation, and how much is disregard for reality? And if it’s always seen as either magical or scary, how does that affect the perception of quantum science?

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.
