[Aspuru-Guzik Group List] February 13 - HQI Special Seminar - Maryam Salehi

by Ploucha, Clare

Harvard Quantum Initiative Special Seminar Wednesday, February 13 3:00 PM Jefferson 250 Maryam Salehi, Rutgers The art of defect engineering in epitaxially-grown topological insulators and topological quantum effects Topological insulators (TIs) are a class of electronic materials which are predicted to be insulating in the bulk and conducting on the boundary surfaces. Since their discovery, material defects have remained as the major obstacle to achieving bulk-insulating TIs. Particularly, efforts to obtain TI thin films with suppressed bulk defects and dominant surface transport have always led to introduction of additional surface defects, thereby shifting the Fermi level away from the Dirac point and deep into the conduction (valence) band. The high defect densities obscure the topological surface states (TSS) and make it impossible to access the Dirac point which is crucial for probing the physics of TSS and the zeroth Landau level as well as fabricating TI-based devices. In this talk, I will discuss how defects have been affecting the properties of TIs and show how suppressing defects in V-VI TIs through a proper interface engineering led to achieving unprecedented low carrier density TI films which revealed the heretofore inaccessible topological quantum aspects of TIs, such as TSS-originated quantum Hall effect, quantized Faraday and Kerr rotation, finite-size topological phase transition, etc.

[Aspuru-Guzik Group List] [qip] QIT Seminar by Nicole Halpern

by Peter Shor

Nicole Yunger Halpern (Harvard) will be giving a quantum information theory seminar this Friday. Friday, Feb. 8, 2-3 pm in the Cosman Room (6C-442) Title: Quantum information in quantum cognition Matthew Fisher recently postulated a mechanism by which quantum phenomena could influence cognition: Phosphorous nuclear spins may resist decoherence for long times. The spins would serve as biological qubits. The qubits may resist decoherence longer when in Posner molecules. We imagine that Fisher postulates correctly. How adroitly could biological systems process quantum information (QI)? We establish a framework for answering. Additionally, we construct applications of biological qubits to quantum error correction, quantum communication, an quantum computation.

[Aspuru-Guzik Group List] ITAMP lunch seminar - Aditya Venkatramani, Harvard (February 7th)

by Zhu, Bihui

*Speaker: *Aditya Venkatramani (Harvard) *Date:* Thursday, February 7th *Time:* 12:00-1:00 pm Includes Pizza. *Title: *Repulsive photons via interaction engineering in a quantum nonlinear medium *Abstract: *Photons do not typically interact with each other, however, special optical media can be engineered to achieve large non-linearities at the single photon level. One way to achieve this is to couple photons to atomic states to from a light-matter hybrid called polariton. We choose one of the atomic states to be a Rydberg state, whose strong interactions manifest in the photons because they are both part of the polariton. Using this technique, we have previously shown attraction between single photons. In this talk I will describe how we control interactions to make it single photons repel each other. I will also show results of measured two- and three-photon correlation functions which characterize these interactions. The repulsion between three photons is stronger than between two photons and shows signatures of interference and spatial ordering. These observations of repulsion between single photons and the ability to control the nature of interactions open a route to creating quantum matter composed of light such as a crystal of photons. *Location: *B-106 @ Center for Astrophysics (60 Garden Street <https://maps.google.com/?q=60+Garden+Street&entry=gmail&source=g>) *Directions: *After entering the lobby of the CfA, turn right to enter the hallway of the B building. In the hallway, turn right again, B-106 will be at the end of the hallway on the left side.
