The optimality of projections for quantum state exclusion
Abel Molina, IQC
We will first motivate the problem of quantum state exclusion of pure states, through its connections with the PBR game and with compatibility conditions for quantum state assignments. Then, we will discuss our recent result regarding the optimality of projections for perfect state exclusion of 3 pure states in 3 dimensions (arXiv:1702.06449).
This is the sixth 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 Viona Duncan.
Dephasing with strings attached
Leonid Pryadko, University of California, Riverside
Is there a difference between the quantum dynamics of a "real" particle and a collective excitation, like that in a spin ice, which creates a measurable gauge field? I will argue that in the presence of weak dephasing, the answer depends on the quantity measured.
Quantum Information Enabled Neutron Interferometry
Joachim Nsofini, IQC
In the quest to explore big quantum systems, there have been opportunities to explore smaller quantum system like the neutron interferometer. A neutron interferometer (NI) has proven to be a useful tool in the study of quantum effects ranging from experiments with single particle interference to measuring quantities of significant importance in condensed-matter and Standard Model physics.

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 . Microfabrication enables the realization of surface electrode ion traps with complex electrode structures.

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.
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.
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.
