Rigorous RG algorithms and area laws for low energy eigenstates in 1D

Thomas Vidick, California Institute of Technology

One of the central challenges in the study of quantum many-body systems is the complexity of simulating them on a classical computer. We give a new algorithm for finding low energy states for 1D systems, based on a rigorously justified RG type transformation.

This is the fourth of the Intellectual Property (IP) Management Lunch and Learn Lecture Series. We are bringing in thought leaders in the protection and management of intellectual property, including many years of experience in relevant areas of information technology.

This session will be led by Jeffrey Wong.

Superconductivity in single-layer NbSe2

Kin Fai Mak, Pennsylvania State University

The discovery of graphene has stimulated not only the field of carbon nanoelectronics, but also studies of novel electronic phenomena in a wide range of atomically thin van der Waals’ materials. In this talk, I will discuss our recent effort in the isolation of a single layer of niobium diselenide (NbSe2), a new non-centrosymmetric superconductor.

The puzzle of genuine multiparticle interference

Sascha Agne, IQC

Two recent experiments demonstrate access to a new realm of quantum phenomena called genuine multiparticle interference. For three photons this means that interference between all three photons is observed while, simultaneously, neither pairs nor single photons display interference.

Quantum Gravity, Tensor Network, and Holographic Entanglement Entropy

Muxin Han, Florida Atlantic University

The relation between nonperturbative Quantum Gravity and tensor network is explored from the perspectives of bulk-boundary duality and holographic entanglement entropy. We find that the quantum gravity states in a space Σ with boundary ∂Σ is an exact holographic mapping. The tensor network, understood as the boundary quantum state, is the output of the exact holographic mapping emerging from a coarse graining procedure of quantum gravity state.

This is the fifth of the Intellectual Property (IP) Management Lunch and Learn Lecture Series. We are bringing in thought leaders in the protection and management of intellectual property, including many years of experience in relevant areas of information technology.

This session will be led by Neil Henderson.

Scalable surface ion traps for high-fidelity quantum operations

Peter Maunz, Sandia National Laboratories

Trapped ion systems can be used to implement quantum computation as well as quantum simulation. To scale these systems to the number of qubits required to solve interesting problems in quantum chemistry or solid state physics, the use of large multi-zone ion traps has been proposed [1]. Microfabrication enables the realization of surface electrode ion traps with complex electrode structures.

Quantum Technology: Theory Research at Strathclyde

John Jeffers, University of Strathclyde

I will provide a short overview of the UK national Quantum Technology Hubs and the theoretical involvement at Strathclyde in two Hubs: the Quantum Communications Hub and the Quantum Imaging Hub.
    

Operational characterization of quantum properties

Marco Piani, University of Strathclyde

 Quantum features like quantum superposition and quantum correlations — the latter comprising, but not limited to entanglement — are both of foundational and applicative interest. We develop tools to characterize such features operationally, looking for ways to detect, quantify, and utilize them. Some recent results I will report on regard the use of such features in the discrimination of physical processes, a task within the area of quantum metrology.

Quantum simulation with laser-cooled trapped ions

Rajibul Islam, Institute for Quantum Computing

Laser-cooled trapped ions are among the most versatile experimental platforms for the simulation of non-trivial quantum Hamiltonians. What distinguishes this platform from others is the extent to which it is experimentally possible to control this system at the level of individual particles and interactions between them.
