Probing light-matter entanglement in the non-perturbative regime of a strongly driven spin-boson system
Milena Grifoni, University of Regensburg
The spin-boson model is an archetype model to study the impact of a thermal reservoir on the coherent dynamics of a two-level quantum particle. When the coupling between qubit and environment crosses a threshold, a transition from coherent to incoherent tunneling between the two qubit eigenstates occurs. At even larger coupling, the dynamics is fully quenched, signaling a strong entanglement of the qubit with the reservoir’s continuum.

Real-time dynamics of lattice gauge theories with a few-qubit quantum computer
Christine Muschik, University of Innsbruck
Gauge theories are fundamental to our understanding of interactions between the elementary constituents of matter as mediated by gauge bosons. However, computing the real-time dynamics in gauge theories is a notorious challenge for classical computational methods. In the spirit of Feynman's vision of a quantum simulator, this has recently stimulated theoretical effort to devise schemes for simulating such theories on engineered quantum-mechanical devices, with the difficulty that gauge invariance and the associated local conservation laws (Gauss laws) need to be implemented.
Airborne demonstration of a QKD payload receiver
Chris Pugh, IQC
We demonstrate the viability of components of a quantum receiver satellite payload by successfully performing quantum key distribution in an uplink configuration to an airplane. Each component has a clear path to flight for future satellite integration.
Quantum entanglement for precision sensing with atoms and light
Onur Hosten, Stanford University
In the last decades, advances in the level of precision in controlling atomic and optical systems opened up the low-energy precision frontier to fundamental physics tests in addition to yielding new applied sensing technologies. In this talk I will focus on our experiments with cold atoms highlighting some of the most recent developments in the prospect of using quantum entanglement to further improve the precision of atomic and optical sensors.
An inversion-symmetry-broken order inside the pseudogap region of a cuprate revealed by optical second harmonic generation
Liuyan Zhao, University of Michigan
The phase diagram of cuprate high-temperature superconductors features an enigmatic pseudogap region that is characterized by a partial suppression of low-energy electronic excitations. In order to understand its microscopic nature, it is imperative to identify the full symmetries both prior to and within the pseudogap region. In this talk, I will describe our experimental results of symmetry properties on YBa2Cu3Oy across a wide temperature and doping range using a recently developed nonlinear optical rotational anisotropy technique.
Join us at the Institute for Quantum Computing for a two-week introduction to the theoretical and experimental study of quantum information processing.
The Women in Physics Canada (WIPC) conference, hosted by the University of Waterloo, Faculty of Science, Department of Physics & Astronomy and the Institute for Quantum Computing, will bring together early career scientists to present their research and hear plenary talks from leaders in physics.
We welcome attendance by people of all genders.
The Quantum Cryptography School for Young Students (QCSYS) is a unique, eight-day enrichment program for students hosted by the Institute for Quantum Computing (IQC) at the University of Waterloo. QCSYS will run August 11-18, 2017 with students arriving August 10 and departing August 19.
The school offers an interesting blend of lectures, hands-on experiments and group work focused on quantum cryptography — a cutting-edge field that utilizes the fascinating laws of quantum mechanics to develop unbreakable encryption that protects communication.
