Seminar

Robert F. McDermott, University of Wisconsin, Madison

One of the remarkable recent discoveries in information science is that quantum mechanics can lead to efficient solutions for problems that are intractable on conventional classical computers.

Applications of the trilinear Hamiltonian with three trapped ions

Roland Esteban Hablützel Marrero, Centre for Quantum Technologies, National University of Singapore

Three coupled harmonic oscillators with an interaction given by the trilinear Hamiltonian $a^{\dagger} b c + a b^{\dagger} c^{\dagger}$ can describe a wide range of physical processes. In this talk I will show how we implement the trilinear Hamiltonian utilizing a chain of three $^{171}$Yb$^+$ ions in a linear Paul trap.

Shining Light on Perovskite Chalcogenides

Colloquium: Jayakanth Ravichandran - University of Southern California

Perovskite Chalcogenides are a new class of semiconductors, which have tunable band gap in the visible to infrared part of the electromagnetic spectrum. Besides this band gap tunability, they offer a unique opportunity to realize large density of states semiconductors with high carrier mobility. In this talk, I will discuss some of the advances made both in my research group and in the research community in theory, synthesis of these materials and understanding their optoelectronic properties.

The NV center in diamond: a versatile quantum technology

Colloquium: Ania Jayich, University of California, Santa Barbara

The nitrogen vacancy (NV) center in diamond is an atomic-­scale defect that exhibits remarkably coherent quantum properties in a uniquely accessible way: at room temperature, in ambient conditions, and even immersed in biological environments. NV centers are being explored for a variety of quantum technologies, including quantum sensing and quantum information processing.

Quantum clocks and information driven heat engines

Seminar: Bhaskaran Muralidharan

We describe two distinct applications of quantum dots [1-3] from a quantum transport perspective. In the first part, we bring in a Bayesian viewpoint to the analysis of clocks, specifically taking the Salecker Wigner clock formulation [4] and explore a novel set up to estimate the tunneling time [1] between electrons in a contact and a quantum dot weakly coupled to it. Using the exponential tunneling distribution as priors for clocks, we analyze the case of a single precessing spin in a quantum dot.

CryptoWorks21 - Intellectual Property: What is it and Why Should I Care?

Back by popular demand, CryptoWorks21 will once again launch the Intellectual Property (IP) Management Lunch and Learn Lecture Series! Our knowledgeable speakers will provide more in-depth presentation built from the previous sessions.

The lectures are designed for researchers working in areas related to information technology, including cryptography and quantum technology.

Toward the first quantum simulation with quantum speedup

Neil Julien Ross, Dalhousie University

As we approach the development of a quantum computer with tens of
well-controlled qubits, it is natural to ask what can be done with
such a device. Specifically, we would like to construct an example of
a practical problem that is beyond the reach of classical computers,
but that requires the fewest possible resources to solve on a quantum
computer. We address this problem by considering quantum simulation of
spin systems, a task that could be applied to understand phenomena in
