Join us for Quantum Today, where we sit down with researchers from the University of Waterloo’s Institute for Quantum Computing (IQC) to talk about their work, its impact and where their research may lead.
Observation and manipulation of a phase separated state in a charge density wave material
Conformal symmetry of fields near the event horizon of the black hole plays a significant role in determining the temperature of the black hole radiation. In this talk, we show how the near-horizon (NH) conformal symmetry provides a microscopic theory for the area-entropy relation for any static or stationary black hole. To do that, we map the NH behavior of the field modes to the scale-invariant Hamiltonian of conformal quantum mechanics (CQM).
In cavity quantum electrodynamics (cavity QED) systems, the realization of strong coupling between light and atoms plays a critical role in the study of quantum optics and entanglement. At the same time, Rydberg atom arrays provide a promising platform for exploring quantum many-body physics. However, with the Rydberg-mediated interactions, atoms mainly interact locally. Coupling Rydberg arrays to a cavity opens up new research directions in quantum many-body physics with long-range interactions, creating a fully connected quantum network.

Optimal Theory Control Techniques for Nitrogen Vacancy Ensembles
Nitrogen Vacancy (NV) Centers in diamond are a very versatile tool. A single Nitrogen Vacancy center is most notably known for sensing magnetic fields, but recently has presented itself as a functional node for a quantum internet, to name just two of its wide ranges of applications.
Quantum Computational Particle Physics
Divide-and-conquer method for approximating output probabilities of constant-depth, geometrically-local quantum circuits

Quantum Information in Relativity: Measurements and Causality
In this talk I will introduce digital quantum algorithms for two quantum simulation tasks: ground state preparation/energy estimation, and real-time dynamical simulation of infinite-dimensional quantum systems. For the former I will introduce a black-box oracle setting that is suitable for quantum chemistry applications.
